ok, i have seen a few z/g's on the dyno before, turn vdc off and usually good to go. brake or abs light maybe come on but usually turns off before they leave the parking lot.

but this time i do my dyno time, and leave, the ABS/BRAKE light on of course... but it has been on for a solid week now... i disconnected the battery for a hour, no change... maybe leave it disconected longer?

ideas?

 

Should go off after the first start without an ABS/TCS fault.

 

thats what i thought/ always have seen... but not in this case...

 

Hook it up to a scanner and see what abs code
