thebestengineer:
Hello, Please i need help.
I am a graduate in the field of electronics &telecoms with many years of working experience. i currently have a job I am doing but there is no more prospect in my present organization. I desire to follow a passion that will also be lucrative. And out of all am good at, I am deciding for automotive (even though it is not in the same field with what I am currently doing). I have little knowledge on car,repairs and maintenance but i need to have thorough training on this aspect of engineering. I have tried to search on-line for where i can get training on autos but have not seen.
Please does anyone know how to begin with this passion. What training I can go into and where I can get the fundamentals and enhance my understanding.
Besides, i desire to go deep into autos but I don't know where to begins (I HAVE PASSIONS FOR REPAIRS AND MAINTENANCE). How do I realize this passion

Which automotive curriculum would you rather be trained with?

This?

HRtechnique:
Lagos.
I, wife and two kids.
Will keep the car till im blessed.
No make or model in mind. Im open.

Please study my Quora link above...it says everything you should in mind, that I would like you to know, so there is no need for me to reinvent the wheel

Where are you based

pjosh1:
I use a Lexus es 330 and I have changed the battery twice in a week, at first I thought the battery I bought was fake not until I bought the second battery and I still have the same problem. Whenever I park and off the engine the car refuses to start unless I start the engine with another battery then put in back mine. I don't think it's the alternator because sometimes after using another battery to start the car I can still drive it out, park and come back home without giving me problem and sometimes it just won't start​ after I park. I also noticed when I'm driving at night if I put on the headlight my dashboard light will go off, the AC will go off and the DVD system and sometimes even without putting on the headlight​ the AC and DVD goes off.
I'm afraid of calling a rewire to come check it because they sometimes just create extra problems.
I just bought the car not up to a month

tizteezy:
Thank you for the insightful stuff.
However, if I'm being honest I understand very little of what you said there.

I've never owned a car, just started learning to drive. I intend getting a car. I don't have huge budget, just a hustling guy.

So, I need a dependable vehicle, low maintenance, good fuel economy, etc at budget under 2 million naira

Do you advise I run away from Volkswagen 2007 - 2012 edition ( where my budget seems to reach)??

Or do you have better suggestions?

A response will be appreciated

I wasn't ignoring you.

I have been busy.

First of all read this https://www.quora.com/From-a-car-mechanics-point-of-view-which-car-make-and-model-is-more-reliable-and-easier-to-fix-when-it-breaks/answer/Jason-Mays-4?share=864b9798&srid=i2UPB

I will come back to the question is Volkswagen 2007 - 2012 edition a good choice

We have extended coverage to Mercedes Benz.

So if you want someone thorough, painstaking, detailed, educated and even more importantly, someone who places premium on continuing education to remain current (in realization of the fact that today's cars are so different from yesterday's cars)

There is no better source or fountain of knowledge about a car than its manufacturer. ...we do it by the book.

oppre26:
Interested. Sent you an email.

Will respond...just so many responsibilities to juggle.

and by the way


We have changed the scope, it does not matter where you are, so long as you are in Nigeria, you can play a part in this.

Kashif:
Wow!

You need a good electrician who can scope signals. Automatics won't work well without a clean VS signal. The signal is generated, but it either doesn't get to your PCM, or gets there too weak for the PCM to make any meaning out of it.

To all technicians here, don't think of replacing any gear without establishing what the computer is commanding first. If there are no flares, you are most likely down with electrical issue(s).

Oscilloscope?

Am I on the right path to sort out the electricals first?

Did Hyundai discredit anyone?
Hyundai has America's Best Warranty

mayor2013:
@ the bolded. Do you need to discredit your fellow human just to be heard. I just tire for Nigerians

Did I discredit anyone in particular?

First of all

Study Hyundai, when everyone else was offering 5 year, 60,000 mile warranty

Hyundai decided to offer 10 year, 100,000 mile warranty.

I am doing exact same thing.


Whatever I repair, I will back up for the next 6 months and 12,000 miles, if it goes bad I will fix it, diagnose it, and replace the bad part and extend your warranty by the number of days it takes me to get it fixed.

That is my marketing strategy it sets me apart from those who want to take money but refuse to stand by their work.

Shall I share with you the adverts Hyundai put up then?

Secondly, I have studied the relevant documentation and it does not seem to me that his transmission is faulty or was every faulty in the first place.

Do I owe him a duty to tell him?

One more detail, I reached out to him in private but he never responded.

Do I owe him a duty to show why he should do business with me?

I guess I commended you and autologic and even recommended a demigod on this forum who decided to react in a most uncivilized manner.

Tell me again, did I discredit anyone?

When they tell you that anyone can fix a Honda

Tell them that Honda says, not anyone can fix a Honda!

You need to be trained on Honda technologies to fix a Honda appropriately

In Toyota's words, Toyota, and the auto industry, considers ASE to be the "Gold Standard" for "independent" certification of service technician's skills and knowledge

Even Toyota supports the best possible training an automotive technician can have in this world:

How do we move from here?

1. The speed sensor input (wiring between the Skid Control ECU and the Instrument Cluster aka combination meter) needs to be checked, see picture 1

2. The speed sensor output (wiring between the Main Body ECU, the sliding roof ECU, the ECM, and the Instrument Cluster aka combination meter Junction Box, the navigation receiver assembly, the radio receiver, the tire pressure warning ECUs as well as the Stereo Component amplifier) needs to be checked

To my mind, this is where your problem lies and not in a transmission replacement


3. What makes you certain that your vehicle is Canadian? Did you run a VIN check?

Even if you run a VIN check, it may be necessary to run the VIN check against manufacturer databases of vehicles of your make/model with known faults? So please send me your VIN via WhatsApp or Email so I can run a check as I earlier requested, I do not recommend posting VINs online.

I strongly believe that the transmission was not procured pro bono, neither was it installed pro bono. I stand to be corrected though.

How much are you willing to pay so I can give you clear and concise instructions so that you can get this off your back?

While you consider that, remember that to the best of my knowledge and belief, no other Nigerian automotive technician on nairaland has provided the iron-clad guarantee that I offer when you engage my services.

HenriXI:
The speedometer needle works fine - That's obvious in the picture i posted earlier. And it doesn't behave erratic.

Great.

But there's something i noticed today.

I tried viewing the Vehicle Speed live data from the Engine/ECU part of my scan tool, but it registered 0 mph even when the vehicle was in motion... (Picture attached)

N/B: If i view the live data from the ABS/TRAC/VSC part of my scan tool, the vehicle speed registers correctly and exactly as it is on my vehicle speedometer.

With these findings its fair to say that the vehicle isn't getting signals from the transmission mounted VSS at all...

I am leaning towards the conclusion reached by my dear brother autologic who said and I quote:

You have modules communication issues via the instrument cluster ,PCM is unable to retrieve VSS successfully from abs modules and this could be probably due to instrument cluster issue
To confirm this ,use a professional scan tool to scan the PCM module and confirm if you a have corresponding VSS values that is same as abs VSS.
Note that ABS is the source of VSS for other modules and the instrument cluster is the gateway modules for other the vss in that particular model of vehicle.

Italics mine
Were you assisted in anyway by a third party, either by suggestion or direction or nudging that you should compare values between the ECU speed data and the ABS speed data other than perhaps by the above quote?

Let me make it very plain what your issue seems to me to be:

1. You are telling me that what the ECU sees is different from what the ABS/TRAC/VSC sees, which seems to indicate that
2. Put another way, there is no communication between the ECU and the ABS unit?
3. If that is the case, was a new transmission really your problem? Because you have not moved from your last stop despite the time and the expense

N/B: I'm using a new transmission and the VSS that came with it.

The more I look at it, the more, I find it hard to believe that the diagnosis administered for your pains was appropriate.

How do i proceed from here

Let me address this in a separate post.

Should i ask an auto electrician to strip the wire harness all the way to check for frayed wiring

Not yet.

HenriXI:
I'm sorry I've been off for some days now... I've actually been dealing with the money I've lost over the past 3 weeks trying to find solutions to my car issues...

I understand, I work upwards of 18 hours a day chasing the same thing.

I had the car checked by Mike @King.reign and he confirmed it's a transmission issue...

Yes!!! I got a new transmission. It was carefully installed (with two gallons of original Toyota WS oil @17k each - that set my account about 150k backwards)

Transmission issue he said? Did he also procure the transmission for you? Who did the install for you? Did you keep the old transmission? I noticed you have come online since then...you should have reached out to me all along. See my advice in a similar scenario https://www.nairaland.com/4193071/electrical-faults-brain-box-burnt#62665475 which may be summed up in the words: If the problem were a new transmission, then the new transmission should have cleared the problem.

And the result was undesirably the same... It shifts from 1-3 and stays there. Same P0500 code.

This raises the question...was it
1. a Transmission issue?
2. something else?

To respond to your questions, Yes the brake lights come up only when i step on the brakes.

That part of the circuit could be bad and could cause your problem, it is now ruled out

TRYGO:
To the OP, I feel your pain here.

Some questions for you though.
1. How many miles on her now?
2. I can only see pending codes on the results. Is the code that is on display what they did fix?

Here are my humble submissions:
1. If the code on display, was a current code, and not a pending one, replacing the camshaft sensors, as you claimed, won't solve that problem.

In some cases, it does.

Basically, what is happening on that car are as follows:
a) you may have being using wrong viscosity engine oils for your car. For instance, of you use, say, mineral oils, with its limited additives in them, with time, theses additives that are part of mechanism needed for lubrication of internal engine parts, gets oxidized,and degraded, causing sludge buildup that would if not checked, hamper the operations of the car's VVTi system.

b) is either the vvti itself is faulty, and not the camshaft sensors that were replaced.
Inspect the wiring harness on the vvti circuitry, and even the camshaft sensors wires also.
If the wires are chamfered, the signals emanating from the vvti/camshafts would be erratic, and the ECU won't be able to interpret such signals rightly.

c) camshafts vvti gears maybe be off its timing.
Check the gears and realigned, if possible.


So, in summary, your predicament, could be surmised as follows:

¶replace or check the vvti switch, or the wiring harness itself.
Check the wires before opting for a replacement

¶ check the engine oil fill port, for signs of heavy sludge buildup. if present, de sludge the system.

¶ check the camshaft vvti gears for any misalignments. Misaligned gears would trigger up the code.


PS: Never ever replace that catalytic converter or the ECU. It has for nothing to do with this code.


I hope this helps you sort your problem out.

...serving you passionately with a difference.

I have never commented on your posts before, now I will.

Here is what I have to say, never ever stop documenting your work.

That is not the Nigerian way, but it is the way of the world which matters a lot.

Someday someone will ask you for your portfolio, if you have made it a practice to document as I have observed you do, you can easily demonstrate your portfolio without much work.

One more piece of advice...document it online outside of nairaland.

You will be glad you did.

And keep up the work.

Might this offer interest you, or do you know someone who might be interested?

Herd mentality.

In school, we answer questions like
Critically analyze, critically examine, critically evaluate so so and so.

In short, we are exposed to critical thinking.

In life, especially in automotive matters, we drop critical thinking and listen to mechanics whose educational qualifications we cannot quantify.

It is so wrong.....hope it changes

Andy790:
well done sir....

am really interested in automobile electronics...

I wouldn't mind learning under you.

more like an apprentice or intern.

please give me your contact let's talk
thanks

Where are you based? Lagos? Abuja?

This thread refers:

http://nairaland.com/4560475/american-automotive-technician-training-live

We have received lots of inquiries about conducting the same program in Lagos.

If you are in Lagos and are interested, please let us know, by commenting.


We are having a dilemma...should we acquire a venue on the Island or hold it on the Mainland.

If you want it on the Island, Like this post, if you want it on the Mainland, share this post.


This is an informal poll to enable us gauge who needs it more, the Island or the Mainland.

Thank you!

obekediamondfuto:
me, I maintain that if u have used 20w50 more than 3 service change intervals then stick with it. it'll burn oil and leak thru the seals if u switch to factory which translates to shorter service intervals.


autoelect I hail u, I would love to visit and learn more from u.. most of my expertise comes from just the Toyota brand, a Lil hands-on experience with other brands wouldn't hurt.

I would like to address the bolded section in a subsequent post.

Join my e-learning program, you will get access to the same stuff they use to teach automobile technicians in the US of A. It will cost you just N100,000.00 and you will have access for 6 months. more details available here: https://www.nairaland.com/4560475/american-automotive-technician-training-live

Pitokwe:
You mean using the oil specification,despite the mileage or anything?

A LITTLE ABOUT MY BACKGROUND
From the home, I was taught to question any position and be absolutely sure of the sanity of the position before adopting the same.

That was further extended to question an authority on a matter, make him or her defend why you should adopt his or position as yours, and never ever adopt a position on the basis that someone in authority or someone who is highly regarded holds that viewpoint.

So feel free to question even me, and I will defend my position, but have no qualms adopting superior wisdom from anyone else. I will not stop there, I will adopt it and I will tell you why I have left mine for yours.

When I sought higher education, the above position was reinforced, so I adopt the trust but verify mentality.

Even those who taught me automotive technology always said: NEVER FOLLOW AN AUTOMOTIVE TECHNICIANS ADVISE WITHOUT EXPLANATION!

My teachers were foreigners not Nigerians.

It is your car after-all, you need to sure why a decision should go one way instead of the other.

SHOULD I SWITCH OR NOT?

There are two main reasons why 20W50 is advocated:

1. Engine is sick, usually of excessive oil consumption or is noisy, owner is unwilling to repair it, so 20W50 becomes a band-aid

2. Engine is sick, usually of excessive oil consumption or is noisy, owner is unwilling to replace it, so 20W50 becomes a band-aid

Come to think of it, if someone tells you, to treat your engine as condemned, would you just accept it that way without some proof that it is indeed done for?

Since you admit that ignorance is a problem, going forward the more enlightened you are about your vehicle and its operating parameters, the better for you.

My research leads me to a different conclusion from the most of the technicians on Nairaland: My position is that you should switch.

Some professionals will encourage you not to switch.

I will encourage you to switch.

The links below may be of immense help to you.

I delayed responding because of limited access to the internet and an appropriate computing device.


I am going to mix threads that agree with my position and those that don't...an unbiased mind needs to hear both sides of the story before forming his or her conclusions.

http://nairaland.com/4491728/best-20w50-engine-oil#67392165 Especially the comments by VolvoS60 and my responses to those

See the advice I gave on the issue here to someone who wanted to switch http://nairaland.com/3933479/advice-needed-regards-engine-oil

nadis09:
I have a sienna 1999 model xle and I have been unable to drive my since two weeks now due to the engine sensor wire got cut and the car refused to start again and the electrician I called discovered the there's no spark on the high tension plugs and went ahead to the brainbox to cut the story short,the brainbox is damaged now,can a free code brainbox with new key start the engine?
Pls experts here I need your advice
Thank you

There is a reason your vehicle came with an immobilizer.

If you care about meeting your vehicle where you parked it, install an exact fit brainbox.

If it does not matter to go, go the freecode way.

Your car, your choice.

My thoughts though.

Pitokwe:
Hmmmm.

What is the solution?

My mileage is 178k now

Meet with the recommended technician.

Then we will take it from there.

Some people don't recommend switching to the proper weight.

I always do.

That is one thing that must be done.

Pitokwe:
5w50

The car specification is 5w30.

I made an observation to the mechanic,but he said there was no issue.

Likely cause of your problem!

Pitokwe:
Many thanks once more
In fact you guys are too much.

Ignorance played a major role in my predicaments.

For the last service I just I did, not up too 200km now, I used a mobil oil.

Not the brand that matters but the weight.
5w20? 5w30? 20w50?

Check the can again

Pitokwe:
The person he referred me to is called Gazzuzz.

I have spoken to him. He asked me the make of my car and I told him,it a 4 cylinder engine 2003 toyota highlander .

I mention the code the scanner gave.and it he said it may be the timing or excessive sludge .

Though he said I will need to do another diagnosis with him to get his full reports and recommendation.

Will give it a trial. Though he said the diagnosis will cost me 10k.

Hmmmm. I paid 15k for the first diagnosis with the first company.

I will do it anyways.no harm in trials

I agree with the submission.

Sludge or timing or electrical faults.

It is not about the name of the shop you are going to, it is the skill of the technician.

Name maybe a function of the power of advertising and the funds to throw around.

A name may also be a franchise.

If the technician is not solid, not even a name will save him.

What engine oil do you use?

I have written extensively on this sludge of a thing.

Will post the threads for you.

Pitokwe:
Many thanks

I have just spoken to him.his place is quite a distance from me he said.he referred me to another person

Let me know how it goes
