Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

2 eligible posts · 0 unverified posts · 1 discussions match the subject in their title or opening post.

POST 1 / ORIGINAL POSTEROriginal post

I have a 2004 C2 and the ABS/PSM light came on the other day. It happened after I did a full brake job. I thought it was one of the ABS sensors, but when I took it to a shop, the diagnostic computer could not read the ABS unit. The shop did a manual brake test the ABS worked but my PSM button on the dash no longer works. Any suggestions

POST 2Original post

This is happening to me as we speak, and also after a brake job. I've got a couple of threads in play. This is what I learned 1) The switch at the brake pedal is known to fail which causes the ABS and PSM to shut down and throw errors. An obvious sign of a switch failure is if the brake lights don't work, but it can fail in other ways as well. It's easy to find and remove. A quarter turn and it comes right out. 2) If the MAF sensor is dirty or flaky it will cause the ABS and PSM to shut down as well. It's not clear why but it's been documented. In this case cleaning it will work but they are easy and cheap to replace. In my case my brake switch tested good and I cleaned my MAF and I'm waiting to see if the fault returns. If it does I'm going to scan the codes and fix (replace) whatever the scanner tells me is wrong.

This is a source reference. Confirm exact model applicability in the original material.
