Abs
I have a 2002 C5. My dash is lit up stating that I need to service the traction control, active handling and the ABS. I have gone through the onboard diagnostics. No current codes are showing.I have reset the system. Five minutes after driving the notifications reappear again.I suspect that the ABS module is bad but without any codes I am not sure. Has anyone else experience this?

The 2200 series codes suggested you lost battery power or disconnected the battery at some point.
Obviously..the C1225 code for the LF wheel sensor is what you want to troubleshoot.

I thought my EBCM was failing, too. I had the 1225 and 1232 codes. On my car, C5 Diag suspected the connector located by the left front control arm. He unplugged the connector, sprayed a special electrical contact cleaner called Deoxit onto both male and female contacts. Dried them both off, and sprayed a continuity improver called Stabilant 22A. That fixed it! AFAIK, the wheel sensors themselves are pretty bulletproof. Connectors are usually the problem. Best of luck to you......

Care to elaborate exactly where the wire was chafed? If it's the part of the harness that makes all the tight bends on the bearing/sensor itself, I'm not surprised. Several very tight bends in that assembly.....
