Co oznacza ten kod błędu?
The parking assistance camera module (PAC) communicates over MS-CAN, the car's network between control modules. The fault is set when communication on the network is disturbed, either by another control module or by the module's own messages interfering with the network. The control module can then switch itself off, known as bus-off, and it stays off until the power supply is broken.
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 control module
Co możesz zrobić
- 1Check that the fuses are intact and that the connectors on the CAN wires are firmly seated
- 2Read out and erase the fault code, then test drive and see whether it comes back
- 3Have a workshop measure the MS-CAN wires for open circuits and short circuits, and look for a control module that disturbs the network
- 4The central electronic module (CEM) is not replaced for a CAN fault unless the workshop finds an internal fault in it
Objawy, które możesz zauważyć1

Na co może wpływać usterka2
