P1695 No CCD Message From Body Control Module

NAME OF CODE
No CCD/PCI BUS Message From Body Control Module

WHEN MONITORED
With the ignition key on, engine running, auto trans must be in drive, and battery voltage greater than 10 volts.

SET CONDITION
No CCD messages from the BCM for 20 seconds.

THEORY OF OPERATION
The Chrysler Programmable Communication Interface multiplex system (PCI Bus) consists of a single wire. The Body Control Module (BCM) acts as a hub for all modules and connects to the Data Link Connector (DLC). Each Module on the PCI Bus uses a local ground as a Bus reference. Continuous information is broadcast across the PCI Bus in order for Modules to share sensor information from a common sensor.

POSSIBLE CAUSE
- Open BUS wire between PCM and BCM
- PCM BUS circuit internally open
- BCM BUS circuit internally open
- BUS shorted to ground
- BUS shorted to voltage
