DTC P1695: No CCD/J1850 Message From Body Control Module: Testing
- Using scan tool, clear DTCs. Cycle ignition on and off several times. Using scan tool, read DTCs. If DTC P1695 is displayed, go to next step. If DTC P1695 is not displayed, go to step 4.
- Using scan tool, attempt to communicate with BCM. If communication can be established with BCM, go to next step. If communication cannot be established with BCM, repair communication problem. See BODY CONTROL MODULES - CONCORDE, INTREPID, LHS & 300M article in ACCESSORIES & EQUIPMENT.
- Turn ignition off. Disconnect PCM and BCM harness connectors. PCM is located in engine compartment, to left of air cleaner. BCM is located behind left kick panel. Measure resistance of PCI bus circuit (Orange wire) between terminal No. 1 at BCM C3 (White) harness connector and terminal No. 59 at PCM C2 harness connector. See Figure and Fig 1 . If resistance is less than 5 ohms, replace PCM. If resistance is 5 ohms or more, repair open in PCI bus.
- Conditions that set DTC are not present at this time. Perform the following to help identify intermittent condition:
- With engine running at normal operating temperature, wiggle related wiring harness while monitoring related parameters on scan tool. If voltage changes or DTC sets while wiggling wiring harness, repair connectors or wiring harness where wiggling caused voltage to change or DTC to set.
- Review freeze frame information on scan tool. Duplicate conditions present when DTC was set.
- Refer to any technical service bulletins that may apply.
- Visually inspect related wiring harness. Check for chafed, pierced, pinched or partially broken wires.
- Visually inspect related wiring harness connectors. Check for broken, bent, pushed out or corroded terminals.
If a problem is found, repair as necessary. If no problems are found, test is complete.
