    DTC P1687: NO CLUSTER BUS MESSAGE

    1. Turn ignition on with engine off. Using scan tool, check for DTCs. If DTC SPECIFIC GOOD TRIP counter is displayed and equal to zero, go to next step. If DTC SPECIFIC GOOD TRIP counter is not displayed and equal to zero, go to step 5 .

    2. Turn ignition off. Disconnect PCM connectors. PCM is located at passenger's side rear corner of engine compartment. Note location of connectors C1 and C2 on instrument cluster. See Fig. 61 . Disconnect connector C1 from rear of instrument cluster. It may be necessary to remove instrument cluster for access to connectors on rear of instrument cluster.

    3. Using ohmmeter, check resistance between terminal No. 10 (Violet/Brown wire) on connector C1 for instrument cluster and terminal No. 30 (Violet/Brown wire) on PCM connector C3. If resistance is less than 5 ohms, go to next step. If resistance is 5 ohms or more, repair open on Violet/Brown wire between instrument cluster and PCM. Perform TEST VER-2A .

    4. Using ohmmeter, check resistance between terminal No. 9 (White/Black wire) on connector C1 for instrument cluster and terminal No. 28 (White/Black wire) on PCM connector C3. If resistance is less than 5 ohms, replace instrument cluster. Perform TEST VER-2A . If resistance is 5 ohms or more, repair open on White/Black wire between instrument cluster and PCM. Perform TEST VER-2A .

    5. Turn ignition off. It is assumed that an intermittent problem exists with wiring or connectors. Inspect instrument cluster and PCM connectors for miswired, corroded, pushed out or damaged terminals. Inspect instrument cluster and PCM wiring for chafed, pierced or partially broken wires. If terminals are not miswired, corroded, pushed out or damaged and wiring is okay, check for Technical Service Bulletins (TSBs) that may apply. If no problems are found and no TSBs exist, test is complete. If terminals are miswired, corroded, pushed out or damaged, or wiring is damaged, repair as necessary. Perform TEST VER-2A .
