Component Tests and General Diagnostics
Checking Voltage/ground Connection, Accessory USB Unit (AUU)
Checking the supply voltage/ground terminal
Voltage feed Accessory USB Unit (AUU)
Accessory USB Unit (AUU) is supplied with voltage via a voltage input on the control module. When the ignition is on, the power input is powered and
the control module is in active mode.
1. Power input #A C1:1 is supplied with voltage via a fuse from the battery. This power input is used to power the memory in the control module. In
the event of an open-circuit, the control module will be reset and adaptation values and diagnostic trouble codes (DTCs) will disappear.
Checking the power supply
Check the voltage feed cable from the battery to the Accessory USB Unit (AUU) #C1-1 for open circuit, loose connections, contact resistance, and
oxidation. Check the fuse. The voltage must be approximately battery voltage.
