here is my summarized service record about the resolution to my problem:

DTC 1210 CAB undervoltage and 1035 no response from steering angle sensor. relearned steering angle sensor but DTC 1035 returned. diagnostic procedures indicate faulty CAB and faulty Steering angle sensor. Replaced CAB and Steering angle sensor.

Also replaced clockspring with steering angle sensor to address airbag light being on.

Nearly a month later i got the car back again:

DTC's 1035, 1174, 1175, 1178, 1210

load tested and voltage drop tested all related power and ground circuits. checked continuity of all wiring between yaw sensor and CAB. SAS sense wire intermittantly showing 12v. installed temporary jumper wire over SAS sense and 5 volt supply circuits to yaw sensor. disassembled instrument panel and steering column to gain access to system wiring for inspection. disassembled electrical connectors at SAS and yaw sensor to test fit over component terminals. tightened terminals and re-assembled vehicle. found ground G100 on left front fender to be loose. 5=12

Tightened loose ground nut on LF fender (G100)

Replaced yaw sensor.
