This diagnostic trouble code is generated when there is a data transfer problem between the PL3 control software and the PL1 control software. The reception of messages sent on the CAN Bus by the PL1 control software is intermittent or non-existent, indicating an open circuit in the CAN Bus, a short circuit, or faulty CAN Bus terminators.

Reaction:

The control software may exhibit limited or no functionality when this fault is detected.

Recommendations:

Inspect CAN Bus Wiring:

• Check for open circuits or shorts in the CAN Bus wiring. Repair or replace damaged wiring.

Verify CAN Bus Terminators:

• Inspect CAN Bus terminators to ensure they are functioning correctly. Replace any faulty terminators.

Test CAN Bus Communication:

• Use diagnostic tools to test the communication between PL3 and PL1 control software. Identify and address any issues.

Check for Interference:

• Ensure there are no sources of electrical interference affecting the CAN Bus communication.

Note:

Data transfer problems on the CAN Bus can severely impact vehicle functionality. Address these issues promptly to restore proper operation.
