Ipod Cradle, Troubleshooting

iPod Cradle, Troubleshooting

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 ] 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.
