I had the same exact issue with my ASR. At first it was very intermittent. After getting motor mounts done the wires finally gave out and the ASR ligth was on most of the time. Once the harness was replaced I was good to go.

On these early years the wiring harness in this area was made badly, they have a tendency to deteriorate and become brittle, causing all kinds of weird problems.

Have the dealer or a good indie shop take a good look at the wiring harness.
