Explicit resolution reports before identified causes, performed actions and suggestions. Within each level, matching component labels precede direct query mentions and inherited thread context; successful versus unsuccessful discussion counts, owner confirmations and independent discussion support determine order. This is not a probability of success.

Leading evidence: 'Check codes' (no explicit attributable resolution; this is a reported action or suggestion). Across 1 matching discussions, the most frequently mentioned possible cause is 'brake light switch (easy' (1 discussions; 0 report identifying it and 1 suggest it). The most frequently discussed action is 'Check codes' (1 discussions). For that action, 0 discussions report a resolution and 0 report an unsuccessful attempt. No action has an explicit, attributable resolution report under the current rules. These are forum reports and suggestions, not a confirmed diagnosis.

Source reports, not a diagnosis or a success probability. Counts refer to discussions and can overlap.

I did have a check engine light with codes 1128 & 1130; which I cleaned the MAF.

The 1128 & 1130 codes have disappeared, but not that I think about it, I never had the abs & psm before cleaning the MAF.

1128 & 1130 are notorious for MAF...and if the MAF went...cleaning will not help.

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.

POST 1 / ORIGINAL POSTEROriginal post

On my MY2000 C4, when I punch it hard off the line, the abs and psm light on the instrument panel lights up, and they stop working. In order to get it to working again, I have to turn the car off and restart it to reset it. I've done this about three times in a row and each time the same thing happens. Any Ideas?

POST 2Original post

Likely a bad brake light switch (easy to test with a helper) or a bad MAF.

POST 3Original post

get the codes read and stop looking for a guess from us. we'll be happy to help you understand the codes once read.

POST 4 / ORIGINAL POSTEROriginal post

I checked the codes with my OBDII reader and there wasn't any codes stored. I did have a check engine light with codes 1128 & 1130; which I cleaned the MAF. The 1128 & 1130 codes have disappeared, but not that I think about it, I never had the abs & psm before cleaning the MAF. I guess I should just replace the MAF.

Ah, sounds like a MAF. Went through the same sort of thing with mine. http://heelix.multiply.com/journal/item/19 http://heelix.multiply.com/journal/item/20 http://heelix.multiply.com/journal/item/21

What reader are you using? 1128 & 1130 are notorious for MAF...and if the MAF went...cleaning will not help.
