3. CLOCKSPRING Turn the ignition off. Disconnect the Steering Control Module (SCM) C5 connector. Connect a jumper wire between the (V71) S/C Signal 1 circuit and the (V937) S/C Switch Ground circuit in the Turn the ignition on. With a scan tool, read the (V71) S/C Signal 1 voltage. NOTE: The (V71) S/C Signal 1 voltage should be below .2 volts with the jumper wire in place. Is the (V71) S/C Signal 1 voltage below .2 volts with the jumper wire in place? 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. Connect a jumper wire between the (V71) S/C Signal 1 circuit and the Turn the ignition on. With a scan tool, read the (V71) S/C Signal 1 voltage. NOTE: The (V71) S/C Signal 1 voltage should be below .2 volts Is the (V71) S/C Signal 1 voltage below .2 volts with the jumper 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. (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 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 - No >> Go to 6 PM ENGINE ELECTRICAL DIAGNOSTICS - GPEC 9 - 503 |
