Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
IPOD Mount Connector
Special tools and workshop equipment required
- 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 "Test Instruments" in Diagnostic Operation System VAS 5051 or Vehicle Diagnosis and Service System VAS 5052.
Troubleshooting Procedure
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 Prerequisites
- First make certain that the iPOD itself is not the source of the problem, refer to the owner's manual.
- First, perform a "RESET" on the iPOD. Refer to the owner's manual.
- Make sure fuse is OK.
- Check radio/radio-navigation system is free of malfunctions via OBD.
Procedure
-- Remove iPOD mount. Refer to 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, positive, with radio unit switched on.
- at 12-pin harness connector T12, at voltage supply terminal 8, positive, control wire, with radio unit switched on.
- at 12-pin harness connector T12, at terminal 3 voltage supply terminal 31, negative
If the voltage values specified cannot be measured, repair wire connections according to wiring diagram.
If a fault cannot be found, replace iPOD mount.
