Vehicle Connectivity Module (VCM) [2018-2022]

This test is used to establish a connection with the Vehicle Connectivity Module (VCM).

Preconditions 

• Before starting the diagnostic communication fault tracing, it is recommended to perform the test "Having problem with connecting to vehicle? Click here." under "Connected vehicles" or "Run system checks".
• The vehicle has sufficient power.

If no connection can be made, try the following actions:

Instructions 

• Open and close the vehicle door to activate the Vehicle Connectivity Module (VCM).
• Perform a battery reset. Note that both the main battery and the support battery need to be disconnected. Alternatively, do a reset by removing and reinserting the fuse for the Vehicle Connectivity Module (VCM).
• Check the connections one by one to identify any loose contacts to the Vehicle Connectivity Module (VCM).
• Disconnect and reconnect the connections to the Vehicle Connectivity Module (VCM) one by one and check for contact resistance, oxidation or an open circuit.
• Connect with DICE and check whether the communication works. If the communication works, try running a reset via the "Advanced test" button.

If no fault could be found in the previous components in the action list but there still is a problem connecting to the Vehicle Connectivity Module (VCM), there is most likely a fault in the Vehicle Connectivity Module (VCM).

Select one of the four buttons at the bottom to finish.
