Special tools, testers and auxiliary items required
‹› Vehicle Diagnosis, Testing and Information 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 "Test Instruments" in Diagnostic Operation System (VAS 5051) or Vehicle Diagnosis and Service System (VAS 5052).
Procedure for troubleshooting:
The "iPod" mount is not equipped with On Board Diagnostics (OBD).
If signal transmission to radio/radio-navigation system is not functioning, then the voltage supply at harness connector can be checked.
Test requirements:
‹› First make certain that the "iPod" itself is not the source of the problem, => Owner's manual.
‹› First, perform a "RESET" on the "iPod", => Owner's manual.
‹› Make sure fuse is OK.
‹› Check radio/radio-navigation system is free of malfunctions via On Board Diagnostic (OBD).
Proceed as follows:
-
Remove "iPod" mount, => [ iPod Mount ] See: Service and Repair/iPod Mount.
-
Disconnect mount connector under storage compartment.
-
Using Vehicle Diagnosis, Testing and Information System (VAS 5051) or Vehicle Diagnosis and Service System (VAS 5052), measure the
following voltages at harness connector on wiring harness side.
‹› at 12-pin harness connector T12, at voltage supply terminal 6, plus, with radio unit switched on.
‹› at 12-pin harness connector T12, at voltage supply terminal 8, plus, control wire, with radio unit switched on.
‹› at 12-pin harness connector T12, at terminal 3 voltage supply terminal 31, minus
If the voltage values specified cannot be measured, then repair wire connections according to wiring diagram.
If a fault cannot be found, replace "iPod" mount.
