Aha!

I'm getting the ABS PSM error which was discussed here and, as expected, I completely forgot about this thread.

Fortunately it was the first hit when I Googled the error so here I am (again).

In my case the error throws when I'm just driving down the road minding my own business rather than during or after I use my brakes.

Furthermore - I've just completed a comprehensive brake service where I replaced my brake servo, my rotors, and pads....and a steering rack. Lots of opportunity to knock or foul sensors which is what I was thinking was my problem until I hit this thread (again).

After reading this thread I remembered that while I was replacing my brake servo I removed the bracket which fixes in place the push rod from the brake pedal to the back of the servo. Seems like maybe I might have dislodged the switch when I did this. I'm at work now so can't crawl under the dash to check.

I did however ask a workmate to help me check my brake lights and lo and behold my right side brake light is out.

So....

step one is replace that bulb. I hope that makes the error go away.

step two is check to see if the switch has been dislodged or if the plunger is maladjusted.

step three is remove the switch and check the electrics and the operation.

step four is check the sensors at the wheels for external damage and clean the connections at the pigtails.

step four is check the wiring harness at the ABS valve and the ABS pump.

I'll report back.
