Was bedeutet der Fehlercode?
The ICM has found a break in the MOST network. Each control module on the MOST network is a link in a ring, so a break can switch off the infotainment functions. The fault may be in a connector, in the cable or in a control module on the network.
Mögliche Ursachen
- Dirt or damage at the connection for the MOST cable
- Open circuit in the MOST cable
- Damaged MOST transceiver in one of the control modules on the network
- A control module on the MOST network has no power supply
- A damaged control module on the MOST network
Was Sie tun können
- 1Check that the fuses for the control modules in the infotainment system are intact, since a control module without power breaks the network
- 2Check that the MOST connectors are clean and seated. Dirt or damage at the connection can break the signal
- 3Look for damage to the MOST cable, such as kinked or sharply bent sections
- 4Have a workshop with diagnostic equipment find where the break is. It lies in the control module before the one the diagnosis points to, or in the cable between them
- 5Switch the ignition on for a while after the repair and check that the code is not stored again
