Mazda CX-9 BCM Body Control Module
I've got an 08 CX-9 GT AWD with what I think is a bad BCM. The following warning lights are always on:
BRAKE
TCS OFF
OIL PRESSURE
SKID CONTROL
the BSM OFF light blinks
the turn signals on the dash don't blink, but the outside turn signals do work. All voltage inputs to the 7 connectors on the BCM have been verified to be correct. Voltage from the oil pressure switch was verified to be correct - meaning there actually is oil pressure.
I am debating just changing the BCM myself, but I may have learned that the BCM has to be programmed by a dealership. Any thoughts?
Thanks
Tyson

I have the factory manual and a voltmeter. I guess I could check the input for each light (if that's how it works!)
