I just got the ABS/Brake/DSC light trifecta problem. It started last week after driving through a deep puddle in a rain storm here in SoCal. Maybe a coincidence, but I thought it worth mentioning. The lights only come on when the engine is warm.

I tried the troubleshooting procedure (DMM on he ABS module connector), but all the sensors have a reading of 1.385V-1.395V with the DMM on a diode setting - IN BOTH DIRECTIONS. Resistance values are all in the 16-17Mohm range. None of that jives with what's been posted for typical or "bad" readings. So I don't know what to do next. Any advice?

I was going to purchase a new ABS module because it seemed that it had most likely failed, but now I really don't know what to think.
