Hey guys.
I recently got a 99 c5, cammed with intake and full exhaust.
A day after my purchase it started having the traction control, abs, active handling, and the occasional door power cutout and engine speed errors.
I finally got to scanning the codes and here they are.

10-PCM
P0704 H C Clutch Switch Circuit (M/T)
P1571 H C ASR Desired Torque
P1689 H C The delivered torque signal voltage is invalid

28-TCS NO COMM

38-RTD C1780 H C Loss of Steering Position Signal

40-BCM
B0432 H Rear Defogger Relay Circuit
B2723 H PASS-Key Detection Circuit
U1255 H Serial Data Line Malfunction
U1096 H Loss of Communications with IPC
U1016 H Loss of Communications with PCM

58-SDM
U1301 H
U1016 H
U1060H C

60-IPC U1040 H

80-RADIO NO COMM

99-HVAC NO CODES

A0-LDCM
B2252 H Key Cylinder Switch Fault
B2282 H Battery #1 Fault
B2284 H Battery #2 Fault
U1255 H Serial Data Line Malfunction
U1064 H Loss of Communications with BCM
U1016 H ???
U1096 H Loss of Communications with IPC

A1-RDCM
B2283 H Battery #1 Fault
B2285 H Battery #2 Fault
U1064 H Loss of Communications with BCM

A6-SCM
B2860 H Telescoping Column Position Sensor Failure
U1300 H Low voltage on the class 2 serial data circuit.
U1255 H
U1016 H
U1064 H

B0-RFA
U1255 H
U1096 H
U1064 H
U1016 H

So quite a few. I assume not all these are broken at the same time so it could be a connector or grounds. I have checked and cleaned the engine bay grounds. Can you guys point me in the right direction with the rest of the connectors I need to check?
PS: The car was taken to a wiring specialist and I was told it has the infamous ABS problem despite not having the c1214. Let me know what you think.

Thanks for the info man.
I went for a drive tonight and it now has what sounds like a misfire and "reduced engine power" Barely goes 50mph.
Kinda got pissed and dropped it off and grabbed another car but I'll check it soon.

Do you ever have a hard time starting the car, where it cranks but doesn't start?
