both lights came on about midway through a run. the lights remained on. i turned the car off and restarted a few minutes later with no other issues. both lights have remained off for the following 4 runs. any ideas??

 

if you had one wheel in the air when applying the brakes that would set off the abs light..shutting down, restarting and driving would re-set the light

 

Check your MAF. Failure will cause both abs and psm lights...been there myself

 

I had a diverter valve cause the same problem but only when idling. Easy to check though.

 

there is a high speed rise come to think of it, probably 100-115 mph, i think that is when the light came on. hmmmmm????

thanks for the info.....it has been fine since. weird!

 

You might want to check to see if there are any codes stored from the event.

It seems that there are at least a dozen faults that produce this pair of lights, from MAF to ABS to brake switches to steering angle sensor to ride height sensors to ... It seems that any fault codes that make the ECU doubt the legitimacy of its inputs will make it shut down the PSM lest it cause more problems by over-riding the driver based on bad data.

 

Happen to me also changed smoke test neg for leaks, changed MAF still happen once since then and resets it self quickly. Pelican parts was cheapest for the MAF, but i would check for other codes and hold off and see how often it happens and does it reset itself...
