Trac off light

Good morning.

Is the ABS light on as well?

The trac system is part of the ABS system. if you have an ABS light, that system needs to be checked for the failure. once that is repaired the trac system will come back on line.

Nothing wrong with the ABS and there is no ABS warning light that came on.

If I may, the trac light can come on if you have an input shaft speed sensor out on the transmission. can you please read the codes?

Here is a guide:

Please let us know what you find. We are interested to see what it is.

Thanks Ken, I am trying to jump wire the OBD2 connector on the car so I can read the codes correctly, but i am not sure how to use the hair clip method to jump which terminals? is it 4 and 16 or 5 and 16 or 4 and 5? this is what is stopping me.

You cannot jump out the obd 2 connector and get blink codes as you could in the old days with the obd 1 connector. you need a code reader for this operation. you can go to a parts store and have them read it for free.

Roy

Thanks Roy, I will do that.

Get back to us with the code so we can help you continue to a resolution.

Thanks Roy, i believe it is the VSS vehicle speed sensor because the jerky shifting of the transmission happened after a TRAC OFF warning light illuminated on the dash.

If the sensor is bad, it should set a 500 code in the system. better to be sure than guess.

you may be right but I like to be sure when I call a failed part. guesses are expensive and sometimes wrong.

Roy

I absolutely agree with you. i will not start any move without being sure. thanks Roy.

You are welcome.

Keep us updated.

Roy

Will try to do. May our Lord bless you and the family.

Thank you. same to you and yours.

Hi Roy,
i did not have time today to go for code readings at AutoZone. a while ago i started the car and the idle was very hesitating. i checked for any air leaks, could not find a thing. But, the TRAC OFF light went off and the jerky shifting went off too. i went for a drive and the engine was very responsive and the shifting was smooth as for a 2001 car. Hmmm, weird.

Interesting.

when they checked the system, were there any codes stored or in history?

Roy

no one checked my car. i checked it myself. regardless, i will go to AutoZone to look if any code in the system tomorrow. will let you know.

Here is a video that shows the ABS getting scanned:
