Hello. ABS light came on few weeks ago. It was on temporarily in the beginning, but it is on most of time except when I drive constantly over 60mph.
MY is 2004 with 226,000 miles.

I know I should get it scanned first. When the ABS light is on & off, the power mirrors do not work (fuse is ok) and fan doesn’t work (fan light blinks).

Today, I tried cleaning the sensors & connectors without a success.
I pulled the wheels & cleaned the sensors. Also, I cleaned the orange connectors in the engine bay and inside of trunk lining.

What is the life expectancy of the wheel speed sensors?

I guess cleaning helped little as the ABS light is not lit most of time.
But, the abs light comes back on if I use Power mirror, heat temperature knob or AC. These must be related and using the same circuit.

This sounds like more of an electrical issue than component issue. Make sure you don’t have a short somewhere that could be causing problem:

May be a grounding problem.

Found the cause!!

I went to a local shop for ABS scan, but they couldn’t get any readings (they kept bringing bigger scanners).
The technician then looked a diagram for few min and said there is a relay affecting ABS/power mirror/ac under the dash. He showed me the location and suggested me to check.
I left the shop (no charge) & checked under the steering. There are 2 grey relays together. I pulled 2 & switched each other.
It fixed the original problem! This time, power acc port doesn’t work. Also, radio is acting weird.
The other relay must control the power outlet & radio.

I ordered 2 relays. Oem part: 39794-S10-003 (rc5102)
