iPod(R) Mobile Digital Device System, Troubleshooting
Mobile device cradle (with integrated electronics) and data interface with radio or radio-navigation system does not have On Board Diagnostic
(OBD) capability.
If data transfer from mobile device to radio or radio-navigation system does not work, check supply voltage and ground at cradle connection.
Test requirements:
‹› Ensure iPod is functioning properly => Device Operator's Manual.
‹› "RESET" the iPod => Device Owner's Manual.
‹› Cradle power supply fuse OK.
‹› Ensure radio or radio-navigation is functioning properly. Check radio or radio-navigation DTC memory using On Board Diagnostic (OBD)
program.
Special tools, testers and auxiliary items required
‹› Vehicle Diagnostic Testing and Information System ( VAS 5051/5052) (VAS 5051 B shown as example only)
‹› Diagnostic cable (VAS 5051/5a) or ( VAS 5051/6a) or (VAS 5052/3)

Measure the following values at electrical connection wiring harness side using Vehicle Diagnostic, Testing and Information System (VAS
5051/5052).
‹› at connector T12, terminal 6 = voltage supply, battery voltage, with radio switched on.
‹› at connector T12, 1terminal 8 = voltage supply, battery voltage, control wire, with radio switched on.
‹› at connector T12, terminal 3 = Ground (GND) terminal 31
If indicated values are not present, check wiring and connections between radio and device cradle using wiring diagram.
If no wiring fault is determined, replace complete device cradle.
