1 1 1 1 1 1 1 Disconnect the ECM connector, DL01, and the IC connector, IP10. Is the resistance greater than 5 ohms? REPAIR the CAN + circuit. For additional information, refer to the wiring diagrams. CLEAR the DTC, test the system No GO to C11 . C11: CHECK CONTINUITY OF THE CAN - CIRCUIT BETWEEN THE ECM AND THE IC Measure the resistance between: Vehicles with 2.5 and 3.0L engine - EN16, pin 123 (G) and IP10, pin 18 (G). Vehicles with 2.0L petrol engine - EN65, pin 88 (G) and IP10, pin 18 (G). Vehicles with 2.0L and 2.2L diesel engine - DL01, pin 73 (G) and IP10, pin 18 (G). Is the resistance greater than 5 ohms? REPAIR the CAN - circuit. For additional information, refer to the wiring diagrams. CLEAR the DTC, test the system No GO to C12 . C12: CHECK FOR LOSS OF TERMINATION WITHIN THE ECM To test: Vehicles with 2.5 and 3.0L engine - Measure the resistance between pins 123 and 124 of the ECM. Vehicles with 2.0L petrol engine - Measure the resistance between pins 88 and 89 of the ECM. Vehicles with 2.0L and 2.2L diesel engine - Measure the resistance between pins 54 and 73 of the ECM. Is the resistance between 110 and 140 ohms? GO to C13 . No Please check part is not on any form of prior authorization before replacement. C13: CHECK FOR LOSS OF TERMINATION WITHIN THE IC Measure the resistance between pins 17 and 18 of the IC. Is the resistance between 110 and 140 ohms? POSSIBLE intermittent fault. Recheck DTCs. No INSTALL a new instrument cluster. Instrument Cluster (413-01 Instrument Cluster, Removal and Installation). CLEAR the DTC, test the system for normal operation. PINPOINT TEST D : P1638: CAN NETWORK MALFUNCTION, INSTRUMENT CLUSTER (IC) TEST CONDITIONS DETAILS/RESULTS/ACTIONS D1: CHECK THE IC FOR DAMAGE Inspect the IC for damage. Does the IC indicate any signs of damage? INSTALL a new instrument cluster. Instrument Cluster (413-01 Instrument Cluster, Removal and Installation). CLEAR the DTC, test the system for normal operation. No GO to D2 . D2: CHECK CAN + FOR SHORT CIRCUIT TO GROUND Turn the ignition switch to the OFF position. Is the resistance less than 10,000 ohms? REPAIR the short circuit. For additional information, refer to the wiring diagrams. CLEAR the DTC, test the system No GO to D3 . D3: CHECK CAN + FOR SHORT CIRCUIT TO BATTERY Measure the resistance between the diagnostic connector, pin 06 (Y) and pin 16 (OY). Is the resistance less than 10,000 ohms? REPAIR the short circuit. For additional information, refer to the wiring diagrams. CLEAR the DTC, test the system No GO to D4 . D4: CHECK CAN - FOR SHORT CIRCUIT TO GROUND Measure the resistance between the diagnostic connector, pin 14 (G) and GROUND. |
