Default 97 and I have some codes . . .

Hey guys I have a few codes on my 97 that I was hoping someone could help me narrow down the issue.

PCM
P1571
P1644
P1652

TCS
No Comm

RTD
C1780

BCM
B0844
U1096

IPC
1056

I also have a service engine message, abs light, and traction control light. Any help would be great.

The TCS No Comms is a PROBLEM for sure, you have a loose connector somewhere. It's causing the Service Engine message. Start poking around the EBCM, I think it in the back above the transaxle on the 97'

Yeah I figured that might be an issue. Lol. I've had the car going on 3 years now and every time it gets below 35* here and I hit a bump the dash would light up like it does now. It would just clear out with clearing the codes and cycling the ignition key. Looks like I'm going to playing with the ebcm harness.
