3. CLOCKSPRING Turn the ignition off. Disconnect the Steering Control Module (SCM) C5 harness connector. Turn the ignition on. With a scan tool, read the (V72) S/C Signal 2 voltage. NOTE: The voltage should be above 4.8 volts with the Steering Control Module (SCM) C5 connector dis- With a scan tool, read the (V72) S/C Signal 2 voltage. NOTE: The (V72) S/C Signal 2 voltage should be below .2 volts with the jumper wire in place. Are the Speed Control voltages displayed as described? Yes >> Replace the Clockspring in accordance with the Service Information. Perform the PCM Verification Test Ver. 1 (Refer to 9 - ENGINE - DIAGNOSIS AND TESTING). No >> Go to 4 4. STEERING CONTROL MODULE (SCM) Turn the ignition off. Disconnect the Steering Control Module (SCM) C2 connector. Turn the ignition on. With a scan tool, read the (V72) S/C Signal 2 voltage. NOTE: The voltage should be above 4.8 volts with the connector With a scan tool, read the (V72) S/C Signal 2 voltage. NOTE: The (V72) S/C Signal 2 voltage should be below .2 volts Are the Speed Control voltages displayed as described? Yes >> Replace the Steering Control Module (SCM) in accordance with the Service Information. Perform the PCM Verification Test Ver. 1 (Refer to 9 - ENGINE - DIAGNOSIS AND TESTING). No >> Go to 5 5. (V72) S/C SIGNAL 2 CIRCUIT SHORTED TO VOLTAGE Turn the ignition off. Disconnect the Powertrain Control Module (PCM) connector. Turn the ignition on. Measure the voltage of the (V72) S/C Signal 2 circuit in the Steering 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 - No >> Go to 6 PM ENGINE ELECTRICAL DIAGNOSTICS - GPEC 9 - 515 |
