Anybody See This Before?

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.

I hate that dreaded annunciator light.

No its the annunciator light, annunciator.

 

(Wife complaining about the annunciator light) :D

What exactly is a "brake 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. :thumbs:

 

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

    • This doesn't look like a GM truck. Not needed on a HD truck
    • It varies a ton around me. Some places are still at $5.00 or higher and others are way down into the $4's.   Offroad diesel was $4.02 at the one station I passed today.
    • So after reading the reveal from Chevrolet, I kept asking myself...why did the trim levels change?   Here are the official ones:   Work Truck (WT): The quintessential fleet truck, built with durable, easy-to-clean interiors for commercial or utilitarian use. Custom: A stylish, road-oriented trim that adds a more refined appearance, standard dual exhaust, and modern exterior styling. Custom Trail Boss: An entry-level off-roader featuring a 2-inch factory suspension lift and 34-inch mud-terrain tires on a budget. Silverado: Serving as the new base consumer truck (replacing the previous LT trim), it comes standard with the Z71 off-road package when equipped with 4WD. Trail Boss: Steps up the off-road hardware with the 2-inch lift, 34-inch tires, monotube shocks, an exclusive off-road hood, and more premium interior options. ZR2: The flagship off-roader. It boasts 35-inch mud-terrain tires, Multimatic DSSV dampers, front and rear electronic lockers, forged carbon-fiber interior accents, and an available hardcore Bison Edition (co-developed with AEV). High Country: The pinnacle of luxury. It replaces bright chrome with modern satin chrome, 22-inch wheels, premium leather, real wood interior trim, a panoramic sunroof, and an exclusive front-passenger touchscreen. As others have stated, why would you want a Silverado - 'Silverado' - wth?? LT needs to remain!!!   Also, there will no longer be a dedicated Z71 model.  All 4x4 trucks will have the Z71 package. Carplay is also something that cannot be removed.  Hopefully it will remain.     I am excited about the 5.7L V8 (350 C.I.D.)  Old school Chevy power.  My only concern is whatever version of AFM/DFM cylinder deactivation.  Too bad that isn't an option a buyer can choose to have or not.   I will definitely be stopping by my local dealership when these trucks start showing up.
    • I haven't seen diesel for less than $5.30 anywhere in my area
    • The not as clean as one would assume theme with the new engine oil, that reminds me of comments over the years with mechanics not always being so on board with filling an oil filter, not from the center anyway due to that typically being the clean side of the filter, danger of some contaminant falling into the filter if not careful but the realization now that the oil may not be as pure as one had assumed it would surely be. Yes it would be possible to fill from the small holes but that means messing with something to prop open the anti drain back valve if the filter is so equipped and not damage that valve in the process. Me, I have hardly ever prefilled an engine oil filter however I have prefilled diesel fuel filters with a filter on a fuel bulk tank and for anyone that has messed with diesel engines with filters and units that have a limited or no way of priming them, putting on a dry filter is a bad day to say the least with those crappy systems. But anyway back to not so clean engine oil, indeed perhaps its not so bad after all that I have not made a practice of prefilling oil filters.    As Grumpy Bear commented on keeping things clean, that I really have to wonder what the typical practice is at a dealer or any other shop that changes engine oil, do they make sure to wipe or wash off the oil plug and certainly if it fell into some gunk or onto a dirty floor, or that they wiped the filter mounting flange and didn't go and use some dirty rag and end up adding dirt to the inside of the head of the filter mount. Or be careless in how they stored or handled the new filter and if they were bumping into items under the vehicle with the filter opening facing up and having dirt drop right into the filter and if so right into the threaded center that is on the clean side. The top side, did they clean away the built up gunk that may be around the filler before removing the cap or to be really careful at that point that something right close to the filler hole that was hidden under the caps flange won't fall into the engine. Or did they clean the funnel or was that just laying there covered in oil from the oil change before and dust kicked up from sweeping the floor stuck to the oil and now that will go running into the next persons engine due to just not cleaning the funnel as "they won't know anyway" attitude as that young guy is more worried about taking a break so he can go outside and smoke a joint. Just random points that came to mind when I think about what some hired personnel may do that the shop foreman has no idea of or perhaps the whole attitude of some shops may be "eh ... who cares, they will never know the difference anyway".
