DTC P1695: No CCD/J1850 Message From Body Control Module: Testing

  1. Turn ignition on. Using scan tool, clear DTCs. Cycle ignition on and off several times. Using scan tool, check for DTCs. If DTC P1695 resets, go to next step. If DTC P1695 does not reset, go to step  4.
  2. Using scan tool, attempt to communicate with BCM. If scan tool communicates with BCM, replace PCM. Program the new PCM. See PROGRAMMING . If scan tool does not communicate with BCM, repair communication fault. See appropriate test under COMMUNICATIONS in BODY CONTROL MODULES - CARAVAN, TOWN & COUNTRY, & VOYAGER article in ACCESSORIES & EQUIPMENT.
  3. Turn ignition off. Disconnect PCM connectors. PCM is located on left side of engine compartment, near front of battery. Disconnect Body Control Module C3 connector. BCM is mounted near firewall under left side of instrument panel. Inspect connectors for damaged pins, corrosion and loose terminals. Repair connectors as necessary. If connectors are okay, measure resistance of White/Violet wire (PCI bus circuit) between terminals No. 23 at BCM C3 harness connector and No. 59 at PCM C2 harness connector. If resistance is less than 5 ohms, go to next step. If resistance is 5 ohms or more, repair open in White/Violet wire. See DATA LINK CONNECTORS article in WIRING DIAGRAMS.
  4. At this time, conditions for DTC to set do not exist or fault is an intermittent problem. Start engine and allow it to idle. Ensure engine is at normal operating temperature. Using scan tool, monitor parameters related to DTC while wiggling connectors and wiring harness. If value changes while wiggling connectors and wiring harness, repair connectors and wiring harness where wiggling caused value to change. If value does not change, review Freeze Frame data using scan tool. Attempt to duplicate condition that caused DTC to set. Check for any related technical service bulletins that may apply. Visually inspect related connectors and wiring harness. Repair connectors and wiring harness as necessary. See WIRING DIAGRAMS article. If no problems are indicated, test is complete.
