Anybody See This Before?

[Hidebinder]

My 2001 Silverado has just within the last month starting intermittantly displaying an ABS and a brake annunciator light. The brakes operate just fine and the fluid level is full. Anybody experience this before????

Thanks for your comments.

What exactly is a "brake annunciator light" ?

[Draenor]

Inspect and if necessary clean the wheel sensors.

I hate that dreaded annunciator light.

Sorry, meant to say indicator light. Both lights come on together and the owners manual is no help.

My '01 had the same problem. The light would come on and stay on. I cleaned the wheel sensors as per the forum suggestions. No help at all. Then I took it to a brake specialist and was told the ABS module was bad and the OEM price was $900+ installation. Bull.... I pulled the module off and sent it to be rebuilt by modularmasters. In three days it was returned and installed. Lifetime warranty also. Cost was around $200 I think. Saved mucho $$$ and no more light.

I have a 2001 Duramax 2500HD. The ABS Brake & Brake warning light recently started to come on at 108000 miles. This was an intermittent problem. I bought an Actron ABS Brake Scanner on the web for $150. Scanning the truck, I came up with a code C0265.

This translates into an EBCM relay circuit fault. Thanks to the other postings, I cleaned the 3 frame ground points,found a corroded positive battery terminal, cleaned the mountings for the wheel speed sensors but the light continued to come on. My wife noticed the light went on sometimes when she went over a bump. I could not replicate the going over a bump event.

 

As a final attempt, I crawled under the truck and looked closer at the EBCM ground. I tapped the main harness and noticed the ground wire flexed at the ring lug everytime I tapped the harness. I cut the ground lug off the wire. I removed the remaining crimped wire from the lug (should have bought a new wire lug). I cleaned the copper ground wire, using sand paper. I recrimped the lug onto the wire & soldered the wire onto the lug. I drilled 2-1/4" holes in the frame to tie wrap the ground wire to the frame so the wire would not flex at the lug. I reused the stock bolt to ground the wire. In addition, I added a jam nut onto the bolt after I threaded the bolt thru the frame. The addition of the jam nut allowed be to put some torque on the ground bolt to tighten it.

 

We have been running the truck six days without seeing the ABS & Brake light. No more C0265.

Good to know.

 

Those darn grounds can cause all sorts of problems when they start to go bad. Gotta keep them grounded in reality.

I had this happen the other week. Took it back to the dealership, they cleaned the ground, been fine ever since.

This happened to me back in 2002. The dealer ripped me a new one diagnosing the problem.
