Was bedeutet der Fehlercode?
The infotainment control module (ICM) can detect a break in the MOST network, the fibre-optic ring that links the infotainment modules. Although the code is labelled faulty signal, it describes that break in the network. While the break is present the infotainment functions shut down.
Mögliche Ursachen
- Contamination or damage at the MOST cable connection
- Open circuit in the MOST cable
- Defective MOST transceiver in one of the modules on the network
- A module on the MOST network has no power supply
- Damaged module on the MOST network
Was Sie tun können
- 1Check that the fuses for the infotainment modules are intact. Their locations are given in the owner's manual or on the fuse box cover
- 2Check that every infotainment module receives power and has a good earth connection. One unpowered module breaks the whole network
- 3Look at the MOST connectors for dirt or damage and check they are firmly seated. Each connector carries two fibre-optic wires
- 4With a diagnostic tool, read the fault code after switching the ignition off and on, and see whether it returns
- 5If the fault remains, a workshop must run a ring break diagnostic with diagnostic equipment to locate the break
