Thread: Midnight crew. ABS and Trac Off light flash on start.

Let's start with story time.
For the duration that I have owned this car, a 98 Grand Prix GT, the ABS and the Trac off light have been on. But lately things are changing.... dunh dunh duuuuuuhhh

(Excuse the theatrics, it's late and I'm a little manic from my bipolar lol)

Anyways. Now the lights, both of them, will sometimes flash anywhere from 10 to 15 times once I fully start the car. After they get done with their flashing, both the lights either stay on, or they both shut off for that drive.

I'm thinking there is a gremlin screwing with my wiring. If a hub was bad don't you think it would just stay on indefinitely? Not randomly shut off after owning it for 10 months?

You're probably gonna tell me to go get it scanned, and I'm working on that, sadly no place is open at 2am

Just some odd behaviour in the life of a w-body.

What ohm reading should they be at?

Somebody tell me whats wrong.




still dont know what ohms they should read at...

800-1700 ohms according to Snap-on (Modis), this is for 2001, but should be the same if the sensors are the same P/N. Wide range is due to it being a Hall Effect pickup.
