On Board Diagnostics
Fault Finding
‹› Diagnostic Operation System (VAS 5051) or Vehicle Diagnosis and Service System (VAS 5052)
‹› Diagnostic adapter cable (VAS 5051/5a) or (VAS 5051/6a) or (VAS 5052/3)
‹› Select "Measuring technique" in Diagnostic Operation System (VAS 5051) or Vehicle Diagnosis and Service System (VAS 5052).
Fault finding procedure:
The USB connection is not equipped with On Board Diagnostics (OBD).
If signal transfer to radio/radio navigation system does not work, voltage supply can be checked at connector.
Test Prerequisites
‹› First make certain that the USB or MP3 player itself is not considered the source of the problem, refer to the Operating Instructions.
‹› Make sure fuse is OK.
‹› Check radio/radio navigation system using On Board Diagnostics (OBD) to ensure it is free of malfunctions.
Proceed as follows:
-
Remove storage compartment with installed USB connection. Refer to=> [ Storage Compartment with USB Connector ] See: Accessories and
Optional Equipment/Entertainment Systems/Auxiliary Input / Output Jack/Service and Repair/Storage Compartment With USB Connector.
-
Disconnect connector below storage compartment.
-
Measure the following voltages at the connectors on the wiring harness side using the Vehicle Diagnostic, Testing and Information System (VAS
5051) or the Vehicle Diagnostic and Service System (VAS 5052).
‹› at connector T12, 12-pin, at terminal 6 voltage supply, positive, with radio switched on.
‹› at connector T12, 12-pin, at terminal 8 voltage supply, positive, control wire, with radio switched on.
‹› at connector T12, 12-pin, at terminal 3 voltage supply terminal 31, negative
If the indicated voltage values cannot be measured, then service wiring harness according to wiring diagram.
If no malfunction is found, replace storage compartment with USB connection.
