CLAAS 76BBh: REH Lifting Module Lacks Speed Information from Powertrain CAN Bus

The REH lifting module has not received the actual speed information for more than 1 second over the Powertrain CAN bus. As a result, skid control is inactive or has been deactivated if it was active.

1. 1

   Powertrain CAN bus communication

2. 2

   REH lifting module connection to the Powertrain CAN bus

3. 3

   Signal transmission from the source of speed information to the REH lifting module

1. 1

   Verify the integrity of the Powertrain CAN bus wiring and connections.

   Check for loose, damaged, or corroded connections on the Powertrain CAN bus.

2. 2

   Test the Powertrain CAN bus for signal continuity and proper operation.

   Use a diagnostic tool to monitor the Powertrain CAN bus and confirm the presence of speed data.

3. 3

   Inspect the component providing speed information to the REH lifting module.

   Ensure that the component responsible for sending speed data is functioning correctly.
