5. (V71) S/C SIGNAL 1 CIRCUIT SHORTED TO VOLTAGE Turn the ignition off. Disconnect the Powertrain Control Module (PCM) connector. Turn the ignition on. Measure the voltage of the (V71) S/C Signal 1 circuit in the Steering Control Module (SCM) C2 harness connector. Is there any voltage present? Yes >> Repair the (V71) S/C Signal 1 circuit for a short to voltage. Perform the PCM Verification Test Ver. 1 (Refer to 9 - ENGINE - DIAGNOSIS AND TESTING). No >> Go to 6 6. (V72) S/C SIGNAL 2 CIRCUIT SHORTED TO VOLTAGE Measure the voltage of the (V72) S/C Signal 2 circuit in the Steering Control Module (SCM) C2 harness connector. Is there any voltage present? Yes >> Repair the (V72) S/C Signal 2 circuit for a short to voltage. Perform the PCM Verification Test Ver. 1 (Refer to 9 - ENGINE - DIAGNOSIS AND TESTING). No >> Go to 7 7. (V71) S/C SIGNAL 1 CIRCUIT SHORTED TO GROUND Turn the ignition off. Measure the resistance between ground and the (V71) S/C Signal 1 circuit in the Steering Control Module (SCM) Is the resistance above 100 ohms? Yes >> Go to 8 No >> Repair the (V71) S/C Signal 1 circuit for a short to ground. Perform the PCM Verification Test Ver. 1 (Refer to 9 - ENGINE - DIAGNOSIS AND TESTING). 8. (V72) S/C SIGNAL 2 CIRCUIT SHORTED TO GROUND Turn the ignition off. Measure the resistance between ground and the (V72) S/C Signal 2 circuit in the Steering Control Module (SCM) Is the resistance above 100 ohms? Yes >> Go to 9 No >> Repair the (V72) S/C Signal 2 circuit for a short to ground. Perform the PCM Verification Test Ver. 1 (Refer to 9 - ENGINE - DIAGNOSIS AND TESTING). 9. (V71) S/C SIGNAL 1 CIRCUIT SHORTED TO THE (V937) S/C SWITCH GROUND CIRCUIT Measure the resistance between the (V71) S/C Signal 1 circuit and the (V937) S/C Switch Ground circuit in the C2 Is the resistance above 100 ohms? Yes >> Go to 10 No >> Repair the (V71) S/C Signal 1 circuit for a short to the Steering Control Module (SCM) circuit. Perform the PCM Verification Test Ver. 1 (Refer to 9 - ENGINE - DIAGNOSIS AND TESTING). PM ENGINE ELECTRICAL DIAGNOSTICS - GPEC 9 - 659 |
