DIAGNOSIS AND TESTING

Overview

The video system combines a number of the networks and modules on the vehicle to provide a full entertainment package to the passengers.

Because of the complexity of the system, there are a variety of different techniques involved in diagnosing the system, as the networks used include medium speed controller area network (CAN), media oriented system transport (MOST), and other system-specific methods.

For information on the description and operation of the video system, refer to the relevant section of the workshop manual.

For information on the description and operation of the networks, refer to the Network Communications section of the workshop manual.

Inspection and Verification

Verify the customer concern.

Visually inspect for obvious mechanical or electrical faults.

DTC index

NOTE:

Generic scan tools may not read the codes listed, or may read only 5-digit codes. Match the 5 digits from the scan tool to the first 5 digits of the 7-digit code listed to identify the fault (the last 2 digits give extra information read by the manufacturer-approved diagnostic system).
