04 with VSC TRAC and VSC OFF lights - Nothing Else

[bulldog1402]

Not sure what the problem was. It happened on a really cold night when I was cornering and hit a pot hole if that makes any difference.

No lift on my truck and don’t do any off-roading. I guess I will see if it pops up again.

Thanks for your assistance.

UPDATE:

Success with Techstream. What a breeze it was too. Plugged it in and reset all the ZPC memory, then did the utility on there and the lights were off. Took it for a 15 minute drive and they are gone. I knew as soon as I shifted into drive that it worked because previously I was able to get the lights to disappear, but as soon as I shifted into drive or reverse, the two lights would pop.

It seems strange though because I know I did the ZPC correctly with the pins in the OBD. I got all the correct flashing light, etc.

Oh well. The end result is thanks to @Vlad a bunch of clean, verified working ABS/speed sensors which were nasty but confirmed working and a nice new toy in the form of Techstream. I have already changed a few other settings on my rig which have bothered me over the years.

All in, it cost me $28 and a bit of frustration. I’ll chalk that up as a win any day.

Thanks for all the suggestions and help.

A couple of years ago, I also used Techstream to do the ZPC to clear the lights and the code. Was easy. But after that I have a flashing "off" light for the AHC system as I did the rear coil conversion. I just ignore the blinking light. Doesn't bother me. Did you also get the blinking light?

No blinking off button for me and all settings work as they should.

I still have airbags in the rear though.
