When you own a 20+ year vehicle, you need to expect that you will at times need to address issues that randomly pop up. Several weeks ago after work I fired up my baby, put it in gear and started to drive off and after pulling out of my parking space after about 100 yards the ABS light came on. Pulled over, shut the car off, popped the hood just look at any wire bundles I could see. Nothing obvious. Got back in car, turned the key on and check my dash lights. All was normal. Started the car and the ABS light was out. Put it in gear, light stayed out. Started to drive off and the light came on again. Brakes appear to work fine even through hard braking. Assume antilock brakes would not. Did not brake hard enough to check that out. Got home, hooked up my scan tool and received the following error codes: C0265 - EBCM Motor Relay Circuit and C0268 - Pump Motor Circuit Shorted. The next day, the parking brake light also came on. Pulled the 60 amp Abs fuse until I could fully troubleshoot, although I was pretty sure I knew the issue.
So I finally found the time to fix this issue. Again, what a pain in the ass getting this control module out of my Tahoe. When I did this over ten years ago, I had to take the whole thing out including the pump. When I put it back together I replaced the torque bolts with stainless steels bolts and this time i was able to remove just the module, still a pain in the ass. After removing the module, i used a box cutter and screw driver to take the cove off the module and re-soldered the six circled connections on the module. I guess the first time I did this I wasn't as thorough or precise as i should have been. I might have posted my first fix, can't remember, but I used the following videos:
Curious though, my cover did not have the six securing bolts detailed in the videos. No bolts at all nor the connections to have these bolts. Used ATV sealant to secure the cover. Let it dry. and reinstalled the module. Started my baby and no lights. Another success story.
