Root Cause

CAN bus entered error state due to repeated transmission failures.

generic

Workarounds

  1. 88% success Check CAN bus termination resistors (120 ohm at each end)
  2. 90% success Verify baud rate matches all nodes on the bus

Dead Ends

Common approaches that don't work:

  1. Disable CAN error handling 82% fail

    Bus stays in error state

  2. Reset CAN peripheral on every error 78% fail

    Constant resets disrupt communication
