Co oznacza ten kod błędu?
The engine control module (ECM) has switched itself off on the high speed CAN network, which is called bus-off. The code is set when the module notices that CAN communication is disturbed, either by another control module or by its own messages.
Możliwe przyczyny
- Short circuit between the CAN wires
- Open circuit in one of the CAN wires
- Internal fault in another control module on the same part of the CAN network
- Internal fault in the ECM
Co możesz zrobić
- 1Read the codes in other control modules, since another module disturbing the network can set its own codes
- 2Use a multimeter to check that the CAN wires have no break and no short to each other
- 3If you have a diagnostic tool: switch the ignition off and on and read whether the code comes back
- 4Have a workshop determine whether the engine control module or another module on the CAN network is at fault
Objawy, które możesz zauważyć4
- Cruise control does not work at all
- The engine bucks on acceleration
- The engine shudders heavily after engine braking
- Uneven idling
Na co może wpływać usterka3
- The engine control module switches itself off on the network (bus-off)
- The engine control module stays off until the voltage supply has been broken
- When the voltage is switched on again, the engine control module makes new attempts to communicate
