9. (K124) ETC MOTOR (+) CIRCUIT OPEN OR HIGH RESISTANCE Measure the resistance of the (K124) ETC Motor (+) circuit. Is the resistance below 5.0 ohms? Yes >> Go to 10 No >> Repair the (K124) ETC Motor (+) circuit for an open circuit or high resistance. Perform the PCM Verification Test Ver. 1 (Refer to 9 - 10. ETC MOTOR Reconnect the Throttle Body harness connector. NOTE: Measure the resistance at the PCM harness connector to avoid damaging throttle body connector Is the resistance between 2.5 and 25 ohms at closed throttle? Yes >> Go to 11 No >> Replace the Throttle Body Assembly. Disconnect the Battery when replacing the Throttle Body Assem- bly. After installation is complete, use a scan tool and perform the ETC RELEARN function. Perform the PCM Verification Test Ver. 1 (Refer to 9 - ENGINE - DIAGNOSIS AND TESTING). 11. POWERTRAIN CONTROL MODULE (PCM) Using the wiring diagram/schematic as a guide, inspect the wiring and connectors between the Throttle Body and Look for any chafed, pierced, pinched, or partially broken wires. Look for broken, bent, pushed out or corroded terminals. Refer to any Technical Service Bulletins that may apply. Were any problems found? Yes >> Repair as necessary. Perform the PCM Verification Test Ver. 1 (Refer to 9 - ENGINE - DIAGNOSIS AND TESTING). No >> Replace and program the Powertrain Control Module per Service Information. Perform the PCM Verification Test Ver. 1 (Refer to 9 - ENGINE - DIAGNOSIS AND TESTING). PM ENGINE ELECTRICAL DIAGNOSTICS - GPEC 9 - 763 |
