Checking The Component

The infotainment module (ICM) has registered loss of communication with the Accessory USB unit (AUU).

If the fault is intermittent, it has been registered previously but is no longer present. Intermittent faults may occur at start up of the Accessory USB unit (AUU) or may be a different type of fault that occurs on different occasions. The fault is evaluated depending on how it occurs.

In the event of a permanent fault, replace the Accessory USB unit (AUU).

Remedy as necessary.
