What Does P1695 Mean?
The Powertrain Control Module (PCM) is not receiving communication messages from the Body Control Module (BCM) over the CCD (Chrysler Collision Detection) or J1850 data bus. This indicates a network communication failure preventing module-to-module data exchange.
Common Causes
30%
Failed or malfunctioning Body Control Module
25%
Damaged CCD/J1850 bus wiring or open circuit
20%
Poor ground connection at BCM or PCM
15%
Corroded module connectors
10%
Failed terminating resistor on bus network
Diagnostic Steps
1
Step 1: Check for additional communication DTCs in other modules using scan tool
2
Step 2: Verify BCM is powered up and functioning by checking other BCM-controlled functions (lights, wipers, etc.)
3
Step 3: Measure voltage on CCD bus wires (should be approximately 2.5V with key on)
4
Step 4: Inspect all ground connections for PCM and BCM, clean and tighten as needed
5
Step 5: Check continuity of communication wires between PCM and BCM connectors
Estimated Repair Cost
$200 - $1,200
Parts + labor, varies by vehicle and location
The Powertrain Control Module (PCM) is not receiving communication messages from the Body Control Module (BCM) over the CCD (Chrysler Collision Detection) or J1850 data bus. This indicates a network communication failure preventing module-to-module data exchange.
The most common cause of P1695 (No CCD/J185O Message From BCM) is: Failed or malfunctioning Body Control Module
Typical repair costs for P1695 range from $200 to $1,200, depending on the vehicle, location, and whether you do it yourself or go to a shop.
May cause various system malfunctions including instrument cluster issues, security system problems, or drivability concerns. Vehicle may be safe to drive but functionality will be impaired.
Start by connecting an OBD2 scanner to read the code and any freeze frame data. Then follow the diagnostic steps specific to P1695 to identify the root cause.
