3. (K858) 5 VOLT SUPPLY CIRCUIT SHORTED TO GROUND Turn the ignition on. Disconnect the Powertrain Control Module (PCM) connector. Measure the resistance between ground and the (K858) 5 Volt Supply Is the resistance above 1000 ohms? Yes >> Go to 4 No >> Repair the (K858) 5 Volt Supply circuit for a short to ground. Perform the PCM Verification Test Ver. 1 (Refer to 9 - 4. (K858) 5 VOLT SUPPLY CIRCUIT SHORTED TO (K400) SENSOR GROUND CIRCUIT Measure the resistance between the (K858) 5 Volt Supply circuit and Is the resistance above 100 ohms? Yes >> Go to 5 No >> Repair the (K858) 5 Volt Supply circuit for a short to the (K400) Sensor Ground circuit. Perform the PCM Verification Test Ver. 1 (Refer to 9 - 5. (K858) 5 VOLT SUPPLY CIRCUIT SHORTED TO (K167) SENSOR GROUND CIRCUIT Measure the resistance between the (K858) 5 Volt Supply circuit and Is the resistance above 100 ohms? Yes >> Go to 6 No >> Repair the (K858) 5 Volt Supply circuit for a short to the (K167) Sensor Ground circuit. Perform the PCM Verification Test Ver. 1 (Refer to 9 - PM ENGINE ELECTRICAL DIAGNOSTICS - GPEC 9 - 795 |
