- Disconnect the MOST connector from the relevant control module.
- Connect the MOST cable to special tool: 951 2867 MOST instrumentation 951 2867 MOST instrumentation
- Activate the infotainment system.
- Press the VCT2000 symbol.
Check that the communication on the MOST-net works by reading out the status for the parameter MOST locked for at least 30 seconds.
