Checking cables and components, Subwoofer module (SUB)





Checking the fault cause
Check the fault cause as follows:
1. Ignition off
2. Disconnect the MOST connector from the subwoofer module (SUB)
3. Connect the MOST cable to special tool 951 2867 MOST instrumentation 951 2867 MOST Instrumentation
4. Ignition on
5. Activate the infotainment system
6. Check that the communication on the MOST network is functioning by reading off the status of the MOST locked parameter for at least 30 seconds. The parameter indicates whether the MOST network is closed and communication possible
7. If the parameter displays that the MOST network is not correctly connected, check the receiving control module in the same way as above.
The communication on the MOST network is working if the menu text is displayed. If this is the case, the fault cause is in the subwoofer module (SUB). Continue the fault-tracing by checking the component.
The communication on the MOST network is not working if the menu text is not displayed. The fault cause is then in the MOST cable for the next control module. Continue the fault-tracing by checking the fiber optic cable.

Checking cable
- Check the MOST connection. Check for dirt, loose connections and damage
- Replace the MOST cable if no fault is found in the MOST terminal.

Checking the component
- Check the power supply and the ground terminal for the subwoofer module (SUB)
- Check the MOST connection. Check for dirt, loose connections and damage
- Replace the subwoofer module (SUB) if no fault is found.
Click the VCT2000 symbol to read off the status of the MOST network.
Remedy as necessary.
