Silveradobad speed sensor? No ABS, new EBCM

[gmcjohnny]

Here is my situation. My EBCM went bad, I had it replaced with another one. Then at low speeds the ABS would kick on. Dealer said it was the HUB, I asked about the speed sensor, they said no way to change them since they are built in to the hub...Suspicious I was..so I read some threads..I had the dealer test to see what hub was bad, said it was the left front. So I took it home pulled the sensor out and cleaned it. Put in back in. I put my 60amp fuse back in for my ABS. Now the ABS light is on. The good news is that it doesn't go off at 5mph or less and scares the crap out of me, but it doesn't work at all!!!! Do you think it is the sensor still or could it be the hub for sure, or could it be the EBCM, or does it need reset or calibrated somehow? The dealer told me there was no way to calibrate the EBCM. PLEASE DIRECT ME!!!

Talk to Gavin at [email protected] He specializes in EBCM and related brake problems. I had the same problem that you had with the left front sensor having a low voltage. It was cleaned and worked just fine. About a month later the ABS light came on...now I need a new pump. If you need to buy a new sensor the part number is 15716191 and they run about $83.00 from the dealer. Here where I live NADA sells the whole hub assembly with sensor for $213.00.

I was wondering if you had any luck yet. I also have the abs dummy light. I took both sides apart, pulled the abs sensors and cleaned them. Still no luck though. My brakes work fine but the light won't go off.

You need to have your ABS code read from your OBD-II port under the dash. A regular scanner won't do unless it can read ABS codes. I have two scanners that don't. Some parts stores will let you use their scanner for free. You need to call them. The dealer will do it but it costs an arm and a leg.
