Thread: abs and tcs light... still

Ok, so after several months and lots of time and money, I still have the ABS/TCS light. The dealer says its the EBCM, I have put 3 of them in, one of them will work if its cold outside and only for the first time I start the car that day. I have checked the wireing, replaced both front wheel bearings. Are there any other things that might cause this. the rear wheel sensors checked out ok. Also, if I am driving and put it in neutral, the speedo goes to zero, I would think that would have something to do with the front end. But i'm out of ideas. PLEASE HELP. Thanks. Luke

anyone? this is driving me nutzzzzz. Thanks

I just bought my car and my ABS light is on all the time and my traction control light comes on sometimes when I'm just driving down the road next time I start the car it never comes on, just an intermediate problem.

Just joined this forum to find out some answers on the car. I have a lot of reading to do on this forum!

Its the Bosch 5.3 module thats bad. I sent mine to have it repaired and it as work great for the last 4 months. I used these guys: CHEAP ABS Module Repair for Pontiac Grand Prix
theres a couple others that repair them as well, but its much cheaper than buying a new one from the dealer.

I had mine up on the lift and we found out that the actual connector that connects to the bearing was bad. The connector wire just came out when we barely pulled on it, plus it was really corroded inside the connector as well.
