Diagnostic Test
- CHECK FOR AN ACTIVE DTC WARNING:
Turn the ignition off disconnect the 12-volt battery and wait two minutes before proceeding. Failure to follow these instructions may result in possible serious or fatal injury.
WARNING:Do not place an intact non-deployed airbag face down on a hard surface, the airbag propels into the air if accidentally deployed. Failure to follow these instructions may result in possible serious or fatal injury.

- Perform the PCM VERIFICATION TEST. Refer to POWERTRAIN VERIFICATION TEST .
No
- Go To 5.
- CHECK FOR THE (V71/V37) S/C SIGNAL 1 CIRCUIT SHORTED TO THE (V937) S/C SWITCH GROUND CIRCUIT
- Turn the ignition off.
- Measure the resistance between the (V71/V37) S/C Signal 1 circuit and the (V937) S/C Switch Ground circuit at the SCM C2 harness connector.
Is the resistance above 10k Ohms?
Yes
- Go To 6.
No
- Repair the short between the (V71/V37) S/C Signal 1 circuit and the (V937) S/C Switch Ground circuit in the wiring harness.
- Perform the PCM VERIFICATION TEST. Refer to POWERTRAIN VERIFICATION TEST .
- CHECK THE (V71/V37) S/C SIGNAL 1 CIRCUIT FOR A SHORT TO GROUND
- Measure the resistance between ground and the (V71/V37) S/C Signal 1 circuit at the SCM C2 harness connector.
Is the resistance above 10k Ohms?
Yes
- Go To 7.
No
- Repair the (V71/V37) S/C Signal 1 circuit for a short to ground.
- Perform the PCM VERIFICATION TEST. Refer to POWERTRAIN VERIFICATION TEST .
- Measure the resistance between ground and the (V71/V37) S/C Signal 1 circuit at the SCM C2 harness connector.
- POWERTRAIN CONTROL MODULE
- Using the wiring diagram/schematic as a guide, inspect the wiring and connectors between the Right Steering Wheel Switch and the Powertrain Control Module.
