3. (F855) 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 (F855) 5 Volt Supply Is the resistance above 1000 ohms? Yes >> Go to 4 No >> Repair the (F855) 5 Volt Supply circuit for a short to ground. Perform the PCM Verification Test Ver. 1 (Refer to 9 - 4. (F855) 5 VOLT SUPPLY CIRCUIT SHORTED TO (K922) TP SENSOR GROUND CIRCUIT Measure the resistance between the (F855) 5 Volt Supply circuit and Is the resistance above 100 ohms? Yes >> Go to 5 No >> Repair the (F855) 5 Volt Supply circuit for a short to the (K922) TP Sensor Ground circuit. Perform the PCM Verification Test Ver. 1 (Refer to 9 - 5. (F855) 5 VOLT SUPPLY CIRCUIT OPEN OR HIGH RESISTANCE Measure the resistance of the (F855) 5 Volt Supply circuit between the Is the resistance below 5.0 ohms? Yes >> Go to 12 No >> Repair the (F855) 5 Volt Supply circuit for an open circuit or high resistance. Perform the PCM Verification Test Ver. 1 (Refer to 9 - PM ENGINE ELECTRICAL DIAGNOSTICS - GPEC 9 - 211 |
