DTC P1695: No CCD Message From Body Controller

NOTE: For connector terminal ID, see CONNECTOR IDENTIFICATION  . For wiring diagram, see WIRING DIAGRAMS article.
NOTE: The Powertrain Control Module (PCM) and Body Control Module (BCM) communicate messages across the CCD bus, as information from either module is needed to operate their respective systems. Messages from BCM are monitored when engine is running. DTC may be stored in Powertrain Control Module (PCM) if no CCD bus messages are received from BCM for 30 seconds. Possible causes are: open on CCD bus, defective BCM, defective PCM, or defective connectors or wiring.
  1. Turn ignition on with engine off. Using scan tool, clear DTCs from PCM. Start engine and allow engine to idle for one minute.
  2. Using scan tool, check for DTCs. If DTC P1695: NO CCD MESSAGE FROM BODY CONTROLLER with a start run count of zero exists, go to next step. If DTC P1695: NO CCD MESSAGE FROM BODY CONTROLLER with a start run count of zero does not exist, go to step  7 .
  3. Ensure ignition is off. Disconnect PCM and BCM connectors. PCM is located between driver's side front fender and power distribution center, near battery. The BCM is located on behind junction block, just to left of brake pedal. See Fig 1 .

  4. Using ohmmeter, check resistance between terminal No. 59 (Violet/Brown wire) on Gray PCM connector C2 and terminal No. 3 (Violet/Brown wire) on BCM connector "A". Connector "A" is a Black or White connector and may also be referred to as connector C1. 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 PCM and BCM. Perform TEST VER-2A  .
  5. Using ohmmeter, check resistance between terminal No. 60 (White/Black wire) on Gray PCM connector C2 and terminal No. 34 (White/Black wire) on BCM connector "A". If resistance is less than 5 ohms, go to next step. If resistance is 5 ohms or more, repair open on White/Black wire between PCM and BCM. Perform TEST VER-2A  .
  6. Reinstall BCM connectors. Turn ignition on with engine off. Select BCM on scan tool. If scan tool displays NO RESPONSE, replace BCM. Reporgram BCM. See BODY CONTROL MODULE  under PROGRAMMING. Perform TEST VER-2A  . If scan tool does not display NO RESPONSE, replace PCM. Perform TEST VER-2A  .
  7. Turn ignition off. Inspect wiring harness and connectors between PCM and BCM. PCM is located between driver's side front fender and power distribution center, near battery. The BCM is located on behind junction block, just to left of brake pedal. See Fig 1 . If no problems exist, test is complete. If any problems exist, repair wiring or connectors as necessary. Perform TEST VER-2A  .
