Now, You've Gotten A Hybrid Car. What Next? by TRYGO(m): 2:40pm On Nov 12, 2016
Hi, guys. It's awhile. I want to thank you guys for your comments on the last article I wrote about "How you too could identify a hybrid car. What dealers aren't telling you".
Well, if anyone's ox being gored, I'm terribly sorry. Especially, if you're a dealer, and you somewhat feel this article might hamper on your sales output this season. But I think, its not just YOU, making profit. Its about the BUYER'S hard earned resources at stake here.

OK. let's set in motion, Newton's third law of motion now.
Actions and reactions are equal and opposite.

I'm writing this article today, in potential response to some of the concerns have gotten concerning the last article.
Some folks have asked. " What do we look out for, when we finally have a hybrid car, or already own one?".

Deciding to own a hybrid car, doesn't end there.
You got to know what the likely maintenance related issues are, with your particular kind if hybrid car brand. Suffice to say that almost all hybrid car manufacturers share same symptoms of problems from their cars.

The scope of hybrid brand in this article, would cover Toyota hybrids(HSD).

information provided here can be applied to other hybrid brands, in consonance with the manufacturers vehicle manual.

I take no responsibility for your wrong interpretations of the information therein in this article.

If you aren't comfortable working on a hybrid car, row it to the dealership, or get a competent mechanic with knowledge of electronics to handle that for you.

YOU OWN A HYBRID NOW!? WHAT DO YOU WATCH OUT FOR?

1. ABS BRAKE ACTUATOR SYSTEM.
Its a system that's hydraulically and electronically controlled by the cars separate ECU(for the brake actuator).
The actuator brake system, could easily develop faults, due to:

*not using the recommended brake fluids; dirty already existing brake fluids in the brake system reservoir(its usually black in colour) suggesting worn out rubber seals within the brake master, etc;

*leakages at the actuator system itself. This system is both hydraulically and electronically controlled by a separate ECU. This ecu is usually underneath the steering volume, by the left side knee of the driver.

*improper brake bleeding procedure. The front brakes in a Toyota hybrid car are bled using the normal process as employed in a conventional car, while the rear brakes, are bled using a scan tool. The rear bleeding procedure is highly technical. All air bubbles in the rear, and the abs actuator must be bled properly. If this isn't done, its going to be ages trying to expel all the air from the system

*electrical short circuits within the actuator's circuitry, or ABS solenoids relays are reasons for failures.

*The brakes ECU too is a likely culprit area you've got to check, if troubles pop up.
From my experience troubleshooting stuffs like this, I have discovered that when the ABS actuator system fails, the VSC, check brake, etc lights lit up the dashboard, or the MFD. In such situations, the abs motor solenoid relays keeps shorting the circuits. And no matter's done to rectify the fault, if those motor relays aren't replaced, a replacement abs actuator system would suffer the same fate as its predecessor.

THE FIX: Scan the car, if you've got a brake related trouble code; use OEM recommended brake fluids; rectify any abs related issues immediately.

PS: Check the brake fluid reservoir cover for the specifications of brake fluids to use. Some manufacturers don't recommend sulphur based brake fluids. You could also check your cars manual to be sure.


2. INVERTER/CONVERTER ASSEMBLY.
That's the component that sits at the left hand side of your Prius, Camry, or even the Highlander hybrids, at the bonnet. It houses the electronics that coordinates all the activities going on from the hybrid battery to providing motion for the wheels. The electronic components in the inverter circuitry are immersed in a jelly like substance that acts a an insulator, and a heat dissipate.
The inverter /converter assembly is water cooled, using Toyota's SLL(super long life coolant).

This system works under tremendous loads, and has to be cooled, just like a cars cooling system, in order not to fry the inverter assembly.
If the assembly is dead, your car would never move. Its similar to having the transmission system on a non hybrid car damaged.

THE FIX:
Use approves Toyota inverter coolants in the inverter reservoir; using water, would only make things worst. Water has a good thermal conductivity, but when it gets to a certain temperature, it's ability to maintain that thermally is compromised. That's why Toyota's SLL fluid was designed with patented additives to compensate for where the use of ordinary water has failed.
When you use Toyota's SLL coolant, you're prolonging the lifespan of the inverter system.

PS: SLL- Super long life. This coolant has already being premixed from the factory.
Do not MIX it with water or anything. That would mar it's effectiveness.

KILLERS OF INVERTER ASSEMBLY
****Overheating of the inverter assembly as a result electric pump failure""***
***Low on inverter coolants***

3. INVERTER/CONVERTER ELECTRIC PUMP
The pump, is located underneath the inverter assembly. Its an electrically operated pump, and not a mechanical one.

WHAT CAN DAMAGE THE PUMP
**It is intolerant to debris/grits. They impact heavily on the impellers of the pump, thereby reducing the volume of coolants the pump can pump through the inverter assembly for efficient cooling.

**Air bubbles inside the pump, as a result of leaks, low coolant levels in the reservoir, can cause harm to the system(pump and inverter ).
Incorrect bleeding procedure, after an inverter pump has being replaced.

**if your car is an old car, be prepared for some sort of pump failure someday.
Imagine you bought your Prius 2002 from the USA, as a used car. That car would have being being 14years by now, and maybe has got like say, 200, 000mikes on it. Definitely, the pump, would have already started operating below specifications, vis-à-vis the volume of coolants it could move around the inverter assembly's cooling system.
It would be technically wise to replace the pump, as a preventive maintenance service.

4. AUXILIARY BATTERY.
Its a 12volt battery, that only powers the electronics of the car.
Its located at the eight hand side of the boot.
For instance, its responsible for the powering up the accessories, head lights, horns, etc. Since hybrid cars do not have kick starters, the battery isn't used in stating the car.
Batteries (cells) age with time. Don't expect your batteries to last forever, or even for 5years.
In some cars, we've seen batteries lasting for only 2years.

THE FIX:
If its a wet(lead) celled battery, ensure the specific gravity test is within spec.
Your battery man should be able to determine this for you, using a hydrometer. If the specific gravity doesn't meet up with the standard, the battery should be recharged.
Overcharging a battery, would definitely reduce the lifespan of a battery.

5. ELECTRIC COMPRESSOR.
This are DENSOR made compressor, very delicate, and requires proper attention, when problems sets in.

WHAT KILLS THEM? I'll say those compressors don't just DIE, but you might be responsible for the problem.

**Using not recommended compressor oils would damage the compressor.
Recommended compressor oil for Toyota is ND11, and not ND8. ND8 is used in the normal belt driven compressor on conventional cars.
Check with your car manual for the right specification for your car's brand.

*insufficient refrigerant gas could definitely cause an Ac system failure; and the use of substandard refrigerants.

*clogged condenser, would cause the Ac system to automatically shut down, during operation.
Remember. Your car's condenser is the Ac system's "radiator", for effectively cooling the compressor.

*Using wrong cooling refrigerant gas.

6. HYBRID BATTERY.
This is where many hybrid car owners get discouraged buying, or even contemplate selling their hybrid cars.
This is a DC battery with a combined nominal voltage in the hundreds. Though this varies from hybrid car brands and the vehicle type.
Refer to your car's manual for more info about the nominal voltage if your car.
This is the battery, with the real potential to electrocute, that powers your car's hybrid system(inverter/converter assembly, Ac system compressor, electric motors/generators, etc).
Any slight deviation from the car's standard voltage, would have negative impacts on your car, ranging from the car not starting, etc.
This type of batteries are different from the auxiliary battery, in such that their electrodes, are embedded in a highly conductive electrolyte(potassium hydroxide), in a well sealed battery pack.
They're save, environmentally friendly, and lasts more than the 12volt battery.

THE FIX: Don't park the car for more than a week, without driving it. If you won't be around for a long while, give it to a friend to help with cruising it in your absence **""""""""**********


In the coming week, we'll be discussing the BATTERIES FOR THESE CARS, AND HOW YOU COULD BE BETTER OF USING THEM

IF YOU'VE GOT ??s, DROP US YOUR COMMENT(S) ON THE COMMENT BAR.

PLS IF YOU OWN A TOYOTA HYBRID, COULD YOU SHARE YOUR EXPERIENCE(S) WITH US ON THIS FORUM?
I SURE BET YOU, IT WOULD HELP SOMEONE HERE.

I confirm gazzuzz's above assertion. My RX400h was the one he worked on which threw up a code on account of use of wrong engine oil. He sold me a Mobil 1 5W-30 Full Synthetic Motor Oil, 5 qt. to cure the ailment. Ever since I changed the oil the car has been super performing. Its sound has even changed.

Disclosure - gazzuz only pulled out the code and recommended the oil which I bought from him. He refused to do ordinary oil change pleading Company Policy not to touch hybrids. He however surprised me as he allowed a complete stranger walk away with his oil after having effected a bank transfer but without him having received a confirmatory alert.

Oga Trygo, oya begin backtrack.

Aside usual tight tolerance issues, use of oil pressure to control timing, one important issue with the hybrid is; it is a high compression engine. 20w50 oil will easily degrade in it and will not also transfer the heat properly to cool the engine.

THE FIX: Scan the car, if you've got a brake related trouble code; use OEM recommended brake fluids; rectify any abs related issues immediately.

PS: Check the brake fluid reservoir cover for the specifications of brake fluids to use. Some manufacturers don't recommend sulphur based brake fluids. You could also check your cars manual to be sure.


2. INVERTER/CONVERTER ASSEMBLY.
That's the component that sits at the left hand side of your Prius, Camry, or even the Highlander hybrids, at the bonnet. It houses the electronics that coordinates all the activities going on from the hybrid battery to providing motion for the wheels. The electronic components in the inverter circuitry are immersed in a jelly like substance that acts a an insulator, and a heat dissipate.
The inverter /converter assembly is water cooled, using Toyota's SLL(super long life coolant).

This system works under tremendous loads, and has to be cooled, just like a cars cooling system, in order not to fry the inverter assembly.
If the assembly is dead, your car would never move. Its similar to having the transmission system on a non hybrid car damaged.

THE FIX:
Use approves Toyota inverter coolants in the inverter reservoir; using water, would only make things worst. Water has a good thermal conductivity, but when it gets to a certain temperature, it's ability to maintain that thermally is compromised. That's why Toyota's SLL fluid was designed with patented additives to compensate for where the use of ordinary water has failed.
When you use Toyota's SLL coolant, you're prolonging the lifespan of the inverter system.

PS: SLL- Super long life. This coolant has already being premixed from the factory.
Do not MIX it with water or anything. That would mar it's effectiveness.

KILLERS OF INVERTER ASSEMBLY
****Overheating of the inverter assembly as a result electric pump failure""***
***Low on inverter coolants***

3. INVERTER/CONVERTER ELECTRIC PUMP
The pump, is located underneath the inverter assembly. Its an electrically operated pump, and not a mechanical one.

WHAT CAN DAMAGE THE PUMP
**It is intolerant to debris/grits. They impact heavily on the impellers of the pump, thereby reducing the volume of coolants the pump can pump through the inverter assembly for efficient cooling.

**Air bubbles inside the pump, as a result of leaks, low coolant levels in the reservoir, can cause harm to the system(pump and inverter ).
Incorrect bleeding procedure, after an inverter pump has being replaced.

**if your car is an old car, be prepared for some sort of pump failure someday.
Imagine you bought your Prius 2002 from the USA, as a used car. That car would have being being 14years by now, and maybe has got like say, 200, 000mikes on it. Definitely, the pump, would have already started operating below specifications, vis-à-vis the volume of coolants it could move around the inverter assembly's cooling system.
It would be technically wise to replace the pump, as a preventive maintenance service.

4. AUXILIARY BATTERY.
Its a 12volt battery, that only powers the electronics of the car.
Its located at the eight hand side of the boot.
For instance, its responsible for the powering up the accessories, head lights, horns, etc. Since hybrid cars do not have kick starters, the battery isn't used in stating the car.
Batteries (cells) age with time. Don't expect your batteries to last forever, or even for 5years.
In some cars, we've seen batteries lasting for only 2years.

THE FIX:
If its a wet(lead) celled battery, ensure the specific gravity test is within spec.
Your battery man should be able to determine this for you, using a hydrometer. If the specific gravity doesn't meet up with the standard, the battery should be recharged.
Overcharging a battery, would definitely reduce the lifespan of a battery.

5. ELECTRIC COMPRESSOR.
This are DENSOR made compressor, very delicate, and requires proper attention, when problems sets in.

WHAT KILLS THEM? I'll say those compressors don't just DIE, but you might be responsible for the problem.

**Using not recommended compressor oils would damage the compressor.
Recommended compressor oil for Toyota is ND11, and not ND8. ND8 is used in the normal belt driven compressor on conventional cars.
Check with your car manual for the right specification for your car's brand.

*insufficient refrigerant gas could definitely cause an Ac system failure; and the use of substandard refrigerants.

*clogged condenser, would cause the Ac system to automatically shut down, during operation.
Remember. Your car's condenser is the Ac system's "radiator", for effectively cooling the compressor.

*Using wrong cooling refrigerant gas.

6. HYBRID BATTERY.
This is where many hybrid car owners get discouraged buying, or even contemplate selling their hybrid cars.
This is a DC battery with a combined nominal voltage in the hundreds. Though this varies from hybrid car brands and the vehicle type.
Refer to your car's manual for more info about the nominal voltage if your car.
This is the battery, with the real potential to electrocute, that powers your car's hybrid system(inverter/converter assembly, Ac system compressor, electric motors/generators, etc).
Any slight deviation from the car's standard voltage, would have negative impacts on your car, ranging from the car not starting, etc.
This type of batteries are different from the auxiliary battery, in such that their electrodes, are embedded in a highly conductive electrolyte(potassium hydroxide), in a well sealed battery pack.
They're save, environmentally friendly, and lasts more than the 12volt battery.

THE FIX: Don't park the car for more than a week, without driving it. If you won't be around for a long while, give it to a friend to help with cruising it in your absence **""""""""**********

this Toyota highlander 2006 hybrid with error code p0a78 and p0071 , and the car will not move. i eventually found a mecha
TRYGO:
Hi, guys. It's awhile. I want to thank you guys for your comments on the last article I wrote about "How you too could identify a hybrid car. What dealers aren't telling you".
Well, if anyone's ox being gored, I'm terribly sorry. Especially, if you're a dealer, and you somewhat feel this article might hamper on your sales output this season. But I think, its not just YOU, making profit. Its about the BUYER'S hard earned resources at stake here.

OK. let's set in motion, Newton's third law of motion now.
Actions and reactions are equal and opposite.

I'm writing this article today, in potential response to some of the concerns have gotten concerning the last article.
Some folks have asked. " What do we look out for, when we finally have a hybrid car, or already own one?".

Deciding to own a hybrid car, doesn't end there.
You got to know what the likely maintenance related issues are, with your particular kind if hybrid car brand. Suffice to say that almost all hybrid car manufacturers share same symptoms of problems from their cars.

The scope of hybrid brand in this article, would cover Toyota hybrids(HSD).

information provided here can be applied to other hybrid brands, in consonance with the manufacturers vehicle manual.

I take no responsibility for your wrong interpretations of the information therein in this article.

If you aren't comfortable working on a hybrid car, row it to the dealership, or get a competent mechanic with knowledge of electronics to handle that for you.

YOU OWN A HYBRID NOW!? WHAT DO YOU WATCH OUT FOR?

1. ABS BRAKE ACTUATOR SYSTEM.
Its a system that's hydraulically and electronically controlled by the cars separate ECU(for the brake actuator).
The actuator brake system, could easily develop faults, due to:

*not using the recommended brake fluids; dirty already existing brake fluids in the brake system reservoir(its usually black in colour) suggesting worn out rubber seals within the brake master, etc;

*leakages at the actuator system itself. This system is both hydraulically and electronically controlled by a separate ECU. This ecu is usually underneath the steering volume, by the left side knee of the driver.

*improper brake bleeding procedure. The front brakes in a Toyota hybrid car are bled using the normal process as employed in a conventional car, while the rear brakes, are bled using a scan tool. The rear bleeding procedure is highly technical. All air bubbles in the rear, and the abs actuator must be bled properly. If this isn't done, its going to be ages trying to expel all the air from the system

*electrical short circuits within the actuator's circuitry, or ABS solenoids relays are reasons for failures.

*The brakes ECU too is a likely culprit area you've got to check, if troubles pop up.
From my experience troubleshooting stuffs like this, I have discovered that when the ABS actuator system fails, the VSC, check brake, etc lights lit up the dashboard, or the MFD. In such situations, the abs motor solenoid relays keeps shorting the circuits. And no matter's done to rectify the fault, if those motor relays aren't replaced, a replacement abs actuator system would suffer the same fate as its predecessor.

THE FIX: Scan the car, if you've got a brake related trouble code; use OEM recommended brake fluids; rectify any abs related issues immediately.

PS: Check the brake fluid reservoir cover for the specifications of brake fluids to use. Some manufacturers don't recommend sulphur based brake fluids. You could also check your cars manual to be sure.

nic that replaced the inverter and oxyen sensor bank 1 and 2. The car is working now, but with p0031 and p0051 code and temperature gauge does not get to the usual half way line as it use too. I went back to the mechanic and he insisted it's no problem
Re: Now, You've Gotten A Hybrid Car. What Next? by TRYGO(m): 4:06pm On Jan 20, 2017
@ajims. If those codes are still there after replacing the sensors, there are other possibilities I'm thinking of.

* find out if your mechanic erased the codes after replacing those sensors, and enquire if he carried out a drive cycle, in order for the ECU of the car to learn a fix has being done.

########

%%% check if there's a short to ground between the wire harnesses.

%%% check for continuity on the sensors

%%% find out also if the mechanic interchanged the sensors the wrong way

%%% specifically check the fuses on the fuse box at the bonnet area. In some cars, oxygen sensors have got fuse/relays.

%%% check for power supply from battery to the sensors.

%%%trace the wiring harness that goes from the sensors to the ECU.


I hope this helps you.

Joseph
