I've got in the family original owner '99 Regal that is my daily driver. Several times through the years I'd get several of the dashboard lights come on at the same time- Traction off/ABS and I can't be definitive on which of 'Service vehicle soon' and 'Check engine' had come on. In each case, an easily read/pulled ECM code came back to a wheel sensor and I'd try to fix the wiring or just replace the hub/abs sensor assembly.
The light show has come on again. This iteration at least, the 'Service vehicle soon' light is on but the 'Check engine' is not. I'm pretty sure this is how it was in the past too. Problem is I have no codes. From what I've read I'm stuck trying to find someone who can read the BCM. But this behavior and info conflicts with that I was able to read standard ECM codes that related to the wheel sensor in the past. I currently have tried to read codes with a cheap hand-held and also an inexpensive laptop/software based unit and each reveal no codes.
Any suggestions on how to proceed ? I'm looking for inexpensive way to diagnose and then I will do the repair. From some of the online topics that seem to be related to non-ECM code ABS problems, a harness fault is sometimes indicated. I'm not sure how the ECM or BCM would distinguish that from a bad wheel sensor.
