So I have a crazy gremlin going on that I can't figure out. Both lights come on randomly. Sometimes within a few blocks, sometimes within a few miles, and sometimes never. I have replaced the following: MAF, brake light sensor, fuel filter, air filter, oil change, AOS, plugs, coil packs, and tubes. I can turn off the PMS, and the ABS has yet to come on when the ABS is turned off. Has anyone experienced a bad PMS switch, or have any other ideas? Thanks in advance.

Just happened this weekend at the track with a Spec Boxster buddy. His ABS light was intermittent (no PMS on that car). After completely locking up -- we speculated that a wheel sensor was going flaky.

Confirmed by a diagnostic tool -- after investigating -- looks like the wires were damaged.

I'd try a durametric, although a generic handheld OBDII tablet was used.

I have the same issue with my 01 S. Randomly both lights will go on, but checking the OBII shows ABS is fine. I also noticed my cruise control stopped working. Can turn it on but it won’t actually engage.

I’d be interested in a fix myself.
