97 Q45 with ECM and ABS codes.....help asap!!

[JP94ZJ]

I have 97 Q45 and the ABS, TCS OFF, SLIP light are all on. Scanned computer, pulled codes:ECM-ABSTCS COMM NGThrottle Position Sensor 2ABS Motor Failure (OFF MODE)

What gives? I checked the connections and they look good, the fuses are all o.k. I am not sure how to check the ABS relay to check to see if that's working. Is this some sort of Fail Safe mode? I don't even know where to start the diag. I am not very knowledgeable of all this electrical junk.

Any help is appreciated. I need to get this figured out by th weekend!!

Thanks

Have you checked your alternator? Is your battery fresh? Does your service history show an alternator replacement?
