3. (K12) INJECTOR 2 CONTROL CIRCUIT OPEN OR HIGH RESISTANCE Turn the ignition off. Disconnect the Powertrain Control Module (PCM) harness connector. Measure the resistance of the (K12) Injector 2 Control circuit between Is the resistance below 5.0 ohms? Yes >> Go to 4 No >> Repair the (K12) Injector 2 Control circuit for an open circuit or high resistance. Perform the PCM Verification Test Ver. 1 (Refer to 9 - 4. FUEL INJECTOR 2 Connect the Powertrain Control Module (PCM) connector. Turn the ignition on. With the scan tool, actuate the Fuel Injector 2 control to the ON (100%) Using a 12 volt test light connected to 12 volts, check the (K12) Injector NOTE: The test light should be illuminated and bright. Compare Is the test light illuminated and bright? Yes >> Replace the Fuel Injector 2 in accordance with the Service Information. Perform the PCM Verification Test Ver. 1 (Refer to 9 - No >> Go to 5 5. POWERTRAIN CONTROL MODULE (PCM) Using the wiring diagram/schematic as a guide, inspect the wiring and connectors between the Fuel Injector 2 and Look for any chafed, pierced, pinched, or partially broken wires. Look for broken, bent, pushed out or corroded terminals. Monitor the scan tool data relative to this circuit and wiggle test the wiring and connectors. Look for the data to change or for the DTC to reset during the wiggle test. 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 (PCM) in accordance with the Service Information. Perform the PCM Verification Test Ver. 1 (Refer to 9 - ENGINE - DIAGNOSIS AND TESTING). PM ENGINE ELECTRICAL DIAGNOSTICS - GPEC 9 - 195 |
