ABS INOP light?
ABS INOP light? Ever since I got my car dynoed, I got an ABS INOP light in the lower left corner of my dash. They disconnected my abs to my rear to strap the car down, after the dyno session, I connected it back up, its still connected to this day. My ABS still works, but I don't know why this light is on? Does anyone know what the light is for, why it comes on? How can I get rid of it? I disconnected my battery and it was off for a few days, but now its back on, everytime my car is running, its on, its not like its a check engine light and comes on every so often, its always on and its annoying! Please help me get rid of this damn light! Thanks.
How many times has the car been started since the dyno? The dyno run can mess up the sensor on the ABS. Should reset it's self after a few restarts. Mine did. . . . Are you sure the connectors over the rear axle are tightly put back together???
Its been about a year, I drive the car daily, I reconnected the sensor right after the dyno, I've checked it numerous times, I don't know whats the deal. Your light was on after the dyno, then it went off after a few restarts? The only connector I saw that was disconnected was the one that connects on the body of the car.
I would check the wiring and make sure the wires didn't get pinched or anything even though they disconnected it. Are you sure they disconnected it, or was it popped off from the straps, meaning did it get damaged from the straps?

Mine went off and it was the speed sensor on one of the wheels. Basically one wheel is going the wrong speed and the ABS shuts off because it cannot figure out what to do. With a good scanner you can read the sensors and see which tire it is. Wont set off the SES light and cannot be read by AutoTap.
Make sure you check the sensor where it connects to each wheel (behind the hub), the connection near the body of the car, the condition of the lines, etc. Basically, follow the line from each wheel to the main trunk. Then, follow the trunk to the brake cylinder. If you don't find anything loose, frayed, etc., try going to Autozone to get them to read the code (don't know if it'll show on their scanner).
Other than that, I don't know. But, I do know that after dynoing, auto-xing, or RRing, my computer goes nuts and throws me an E-brake, antilock brake, airbag, and whatever other lights it can think of! Basically - the car goes haywire trying to interpret being thrown around a track or having the rear wheels going 130, while the fronts are stationary.
