2000-2012 Mitsubishi Eclipse 2.4L I4
Description
A module CAN transceiver has entered bus-off state due to excessive transmit errors. The module has stopped communicating to protect the bus.
Symptoms
- Specific module completely offline
- System controlled by that module inoperative
- Other modules reporting lost communication with affected module
Common Causes
- Module CAN transceiver failure
- CAN bus wiring short causing transmit errors
- Module hardware fault
- CAN bus impedance mismatch
Diagnostic Steps
- Identify the module in bus-off state
- Check CAN bus wiring at that module
- Test CAN transceiver with scope
- Check for bus impedance issues
- Replace module and retest
Repair Notes
Module CAN transceiver likely damaged. Replace the affected module after verifying CAN bus wiring is good.
