Interesting PSM, ABS...

[superporschefan]

Howdy all,

I know this is a "common" issue, and I've searched the forums for answers, but had a few questions...

On my 02 C2 Tip, My PSM and ABS lights are coming on consistently after 20 mins of driving. Turn the car off and back on, they clear, but again after 20 mins of driving they reappear.

This is highway, cruise control driving. Not even touching the brakes.

I checked the brake lights, they're fine, and I'm looking into the MAF cleaning/replacing now. But I just thought I'd ask to see if this struck a chord with anyone. (*cough* Loren.)

Thanks!

Derek

You have checked the obvious.

The real way to tell is to check for fault codes and view the idle and 2500 RPM MAF readings.

Before doing anything "heavy" check the brake light switch.

I'd start with a check of the battery and alternator; voltage swings often cause both the ABS and PSM MIL's to trigger. A load test of the battery and alternator will tell you if they are involved; beyond that, I would agree with Loren, get it scanned for active and pending codes.................

Thanks guys! I'll get it checked and let you know how it turns out.

Like a leak? Just noticed a small drip of what might be brake fluid on my garage floor...

Well, it turned out to be the Brake Switch! Quick fix and on my way...

The small drip was a oil leak, but it seems to have fixed itself in the past few days. (Gulp.)

Thanks for everyone's input!
