Circuit Description

The Apple iPod is connected to the personal audio link (PAL) through a dedicated interface cable. The cable allows the iPod the ability to share serial data communication, audio signals, power and ground with the vehicle.

Circuit/System Verification

Verify customer complaint by verifying that the iPod(R) is in good working condition and adjust the speaker outputs through the radio controls, fade and/or balance.

Diagnostic Aids

The iPod(R) interface connector was not originally designed for an automotive application and is susceptible to vibration and movement damage. It is recommended that excessive movement of the iPod(R) and cable be avoided while driving.

Circuit/System Testing

Important: Verify that the iPod(R) is in good working order and visually inspect the iPod(R) connector cavity for any signs of damage before performing this diagnostic. Verify the proper software has been downloaded from http://www.apple.com/support/ipod/ to the iPod(R) before performing this diagnostic.

1. Set the radio to the iPod(R) interface menu and attempt to operate audio from the iPod(R).
2. Gently wiggle the interface harness at the connection to the iPod(R). Verify that the iPod(R) interfaces with the radio when the connector is wiggled.

• If the iPod(R) interfaces with the radio intermittently when the connector is wiggled, inspect the iPod(R) connector cavity or interface cable for damage. Replace the suspect iPod(R) interface cable or inform the customer that the iPod(R) may be damaged.

3. Ignition ON, Observe the PAL red LED lamp. Verify the red LED lamp is illuminated.

• If the PAL red LED is not illuminated, go to iPod Audio Distorted or Inoperative - One or More Speakers. iPod Audio Distorted or Inoperative - One or More Speakers

4. Near the BCM connector, verify the serial data circuit from PAL is properly spliced to the CAN 2 serial data circuit.
5. Disconnect the PAL and test the CAN 2 serial data circuit for an open.

• If all circuits test normal replace the PAL.
