Hello House.

I need to make enquiries from the gurus pls.
My car's 'Check Engine' & ' Airbag' light is always on and has been for a long time.
My car has been scanned many times as well and i was told to get a new brain box (or Toks) for the 'Check Engine' light to be permanently off. The car is doing very well except for the light on, so my questions are :

1) Can the Brain box be repaired ?
2) Is the Light on damaging any component inside the car ??

Thanks for your suggestions and counsels.

The lights you have on has nothing to do with your vehicle's brain-box being faulty. The brain-box is functioning well, that's why its relaying those errors.

The airbag light can be due to a bad airbag sensor, or the vehicle might have been involved in an accident and airbag deployed (probably before you bought the vehicle). There are tools for erasing airbag lights - but I would suggest you have it scanned and if there really is no problems, have it erased.

The check engine light can be due to a lot of factors, ranging from irrelevant fault codes to major engine errors. I will suggest you have your vehicle scanned with a diagnostic tool to know exactly what it is.

The highlighted portion is true. But I have had it scanned by my mechanic (rewirer) and he said he was told its nothing and the car is in good condition. They have corrected the code (which resets whenever the battery & plugs are removed wrongly) twice.

so in that case, i would just have the airbag light erased and i'll forever ignore the 'Check Engine' Light.
Thanks a mil.

Thanks Owan. Other opinions are welcome pls

You are welcome.

Like I said in one of my posts today, some diagnostic/scan tools have limitations and might not detect the main issues with a vehicle (I'm not saying thats the case with yours). I bought one of those and found out that it covers basically ONLY emission related errors and faults/codes.

1. Its always better to find out the limits of a diagnostics tool before buying.
2. Its also better to know IF the scan service you had is exhaustive; at least covering full functionalities and operations of the:
a. body
b. Chassis
c. Powertrain

My scan tool for instance has no business with the air suspension on my car and will pass the vehicle even though I'm staring at an Airmatic Error on the dash.

Its very important for you to know these things.

@@@@@@

brain box u mean? u dare not touch it!!! very big mistake

im aint an expert however i got to say what i know

check engine light isnt limited to bad sensors and it can also be bad grounding. normally like they said the grounding is usually mounted near the em thermostart sitting in the engine

as far as ur car is concern with some bad sensor or some bad grounding that isnt anything to worry about cuz u could drive ur car till . . . .

do not upset ur car!!! ur car is fine

OK Man. I wont upset her.
Thanks all.

I guess there's no cause for Control, everything is under alarm.

^^^^
taking the thermostart off wouldnt that makes the check engine light to come ON on itself

since the grounding is sitted somewhere there

what do u think sultan;kule

@Mishoo,
I wont be so fast to jump to conclusion like u just did, there might be a cause for control. Let's start from here,
Airbag light on- It probably might have been on since you bought it, what some dubious dealers do as i have been a victim is that theý'd replace the steering airbag and just replace the cover for the passenger airbag area instead of the airbag itself. It might be the case in this or your airbag sensor assembly has a crack or it is faulty or your airbag sensor(s) has a bad connection or it is faulty. We also need to know the type of car you are talking about. THE DANGER HERE IS THAT YOUR SELF RESTRAINT SYSTEM (airbags) WILL NOT WORK IN THE EVENT OF A COLLISION. Dont take it lightly. Get it checked well. You shouldn't just entrust this case to a rewire.

The check engine light-
Get your vehicle scanned with a professional scanner not an handheld, it you stay aroung Iju area of agege, during the weekend (sunday) i could scan it for you for free, or if you are around badagry during week days (Mon-Sat) i could also offer the same service for free. IT will definite ly pull out a code. Dont let your rewire tamper with the bulb on the instrument cluster or remove the fuse.

Wishing you the best in correcting this fault.

Can you please help me scan my car too
My mechanic said it's d brain box, having gear issues. And has requested I change it...

My car went off on motion and all efforts restarting it was proved abortive. It will roll but won't start. My rewire later diagnosed it and said it was brain box problem. He confirmed there was no light on d plugs and hv checked all d fuse. Pls I need an advice

my brain box is making abnormal noise once the automatic gear is at drive.

Pls I have the same problem, what's your advice?

you have to scan the car to see first, and check the crack angle sensor, timing bet, coil, then you can request for a brain box and see wether it will start,

Please I need help oooooo!
I happened to be a young guy with a 2002 Nissan PATHFINDER. My mechanic has almost made me sell the car as a scrap, due to their habit of making me a money machine. Now the car is not starting, but shocking, which the rewire said it's the brain box. Please can a brain box be faulty and the car still shocks? Please help me o....

I scanned my toyota corolla 2000 and got error code related to vvt and system too lean bank 1. I used it for a while and can that affect my vehicle brain box? And please can the brain box be repaired if it is bad? The car refuses to start now and only try to start but make a sharp sound from close to the oil sensor. Please help. Thank you

My car jerk on slow speed, my mechanic said is brainbox issue

Am new here, pardon me if dis is not the right place to post this,
Can a free code brain box functions normal in a Volkswagen passat 2006 with immobilizer active issue?my electrician suggest to change the brain box to free code brain box and reprogram the vehicle.

Happened to me. I was told the brain box needed to be flashed due to an interpole error

Please my 2010 Toyota Camry is showing Check Engine light and Traction Control Light on the dash.

Please help.

Good day everyone, please I need assistance and suggestions from the gurus in the house.

I drive a Honda civic 2008, the problem is that if I start the car, it will run normally so at some point the airbag light will come up, the gear light will be blinking while the temperature gauge will off. Once this is happening the ac will stop working or blowing hot..

At times if I start it, it will do like that from the starting, I.e. airbag light on, temperature gauge will not come up and gear light will be blinking but aside from all these car running perfectly.

So I took it to the 3rd rewire now only for him to tell me that I will need to replace the brain box.

Please any suggestion on what to do next because I'm fed up....... The scan shows nothing happening to it. Please I'm fed up.

Pls I am an issue with honda accord 2008, 4 cylinder.

Was driving when suddenly, it stopped on the road , it cranks on each trial , but engine wont start.

An electrician and mechanic were called.

Discovered fuel was getting to the engine meaning the fuel pump was ok.


Checked/Tested the spark plugs with the ignition coil and discovered that there was no sparks at the plug head.
Suspecting it was a current issue.

All other sensors connection that was seen still looked connected.

Scanned diagnosis brought like 66 errors codes ,

We suspected brainbox, we brought another brainbox , called someone to program the brainbox. The car started, tried moving front and back, the car moved . BUT THE DRIVE GEAR KEEPS BLINKING.


The brainbox programmer said its because the last serial digit on the new ECM was not exact.

We rescanned with the new ECM and error codes was reduced to 5 error codes


So pls I want to know-
- if the problem is really the brainbox or should another electrician check for something else?

-Can the old brainbox be fixed?

-How much is cost of Honda Accord 2008 brainbox (pple are telling me 170k, which I think is expensive)?

-Finding the exact brainbox has been difficult in PH, what guarantees do I have on brainbox brought from outside the state (Lagos,Onitsha).

Pls help
