   Powertrain CAN bus wiring

2. 2

   BDG module functionality

3. 3

   CAN bus termination resistors

4. 4

   Other modules connected to the Powertrain CAN bus

1. 1

   Inspect

   Check the wiring and connections of the Powertrain CAN bus for damage, corrosion, or loose connections.

2. 2

   Test

   Use a diagnostic tool to monitor the Powertrain CAN bus for ongoing frame errors and identify the source of the issue.

3. 3

   Verify

   Confirm the functionality of the BDG module and ensure it is properly configured within the system.

4. 4

   Check

   Examine the CAN bus termination resistors to ensure they are correctly installed and functioning.

5. 5

   Diagnose

   Investigate other modules connected to the Powertrain CAN bus to determine if they are contributing to the frame errors.
