VSC TRAC/VSC OFF/Check Engine Lit up!!! (1 Viewer)

[gmed51]

Hi Gang,
This morning when I got to work i made a huge right loop in our parking lot turning the steering wheel to the max. As I straightened out all three indicators lit up. Any ideas what this could be? See pic. Hoping this is a quick fix. Let me know what you guys think. Thanks in advance!!!

Could be one of many things. Get an OBDII scanner (pretty cheap) and read your error codes. Same happened on my LC. I was overseas at the time and didn't have many mechanical resources. Disconnected/reconnected the battery and fortunately no lights or codes after that.

I'm not an expert, but perhaps because of what you did in the car park, it could have something to do with 'Atrac' if you've got it fitted.

Get the DTC for the check engine light and fix that first. The VSC/TRAC lights are automatically triggered with any powertrain fault that trips the CEL.

Thank you I'll purchase the scanner and check it out.

An ATRAC issue would not trigger the CEL, but a DTC that kicks on the CEL will always trigger the ATRAC light. Wonky electronics!

No lift truck is 100% stock.

Will do thx.

Is that not the lights for O2 sensor going bad?

Impossible to tell without reading the DTC. Any powertrain fault will trigger all three of those lights.

Finally got some time to click on link you provided. Soon as I get back to work i'm gonna tighten the gas cap and restart. Crossing my fingers this is the quick fix!!! Thanks!!

No, Atrac was fitted at the factory by Toyota, the options were, diff locks, Atrac, LSD, or nothing, it does not involve aftermarket lifts or aftermarket anything.

And as Atrac works by applying the brakes to a slipping wheel, I just thought as you said you had done a "huge right loop in our parking lot turning the steering wheel to the max" it might have been somthing to do with the 'Atrac' ECU sensensing something different, to the norm.

Just a thought.

I have had very little to do with ATRAC as most of the 100's have rear diff locks in the UK, but thanks for the info.

I would highly recommend spending ~$20 on a Bluetooth OBD2 code reader. In about two minutes, you could know what codes are causing the CEL instead of blindly guessing.

I use this with Torque Pro when not using Techstream: Non-Chinesium product

Without pulling the CEL code you have no clue what tripped it. No point doing a google search on it without the code. The other two lights come on automatically when the CEL does, and once you address why the CEL came on the other two will go out.

Recap:
Followed my mechanics advice as far as using the Cataclean additive as per manufactures instructions and drove the LX North to Monterey. 1 week and 700 miles later there were no issues and indicators never turned back on. Now lets see how long this will lasts.

I think you need a new mechanic, or maybe a mechanic, that's what I think. I read on a previous unrelated thread the code was P0430. Your "mechanic" didn't diagnose, cleared the code, and went straight for the snake oil? I agree with @JunkCrzr89 100%, and not only with his use of cool words. The problem could be 10 other things besides your cat.
