Anyone here who can help with ABS light on an '02?
HI, my buddy's '02 Tahoe Z71 5.3L (E-85 compatible) 4x4 w/ 3.73 gears has an issue with the ABS. The truck has 75K miles on it. He has had the ABS light come on the last 2 weeks after every time it's put into gear and starts moving. The red brake warning light stays off. A recall repair was performed on it yesterday at the Chevy dealer to check for corrosion on the wheel sensors. They replaced the right front one as it kept reading low, but it was not the cause of the ABS light coming on, apparently. The truck has two trouble codes: C0281 (and P0268 which I was told was stored in "history"). The truck seems to run fine except for the ABS light. He did just recently have to replace a burned out bulb in the rear right tailight for the brakes.
So how do I go about diagnosing the C0281 code? I have a DMM that I've used extensively over the last 15 years. Do you think it might be the EBCM? I've read about the issues with them staying on, but his doesn't do this, perhaps it's something simple? Or not, lol. Are there any specific wire harnesses I should check over & test? Thanks in advance to anyone who can assist...

Re: Anyone here who can help with ABS light on an '02?
Thanks for that reply. I've been in contact with a GM tech on another site and it sounds like the only thing I can do is to check the EBCM for power (60 amp fuse) & ground, other than that a scanner that reads ABS information is needed if those check out ok...
 I have been finding information on the web that leads me to believe it is the EBCM that's failed as it seems to be somewhat common. There is a company that rebuilds 'em for around $156 on eBay, I might be in touch with them soon, lol.
