Test K: The Video System Is Inoperative/Does Not Operate Correctly
PINPOINT TEST K: THE VIDEO SYSTEM IS INOPERATIVE/DOES NOT OPERATE CORRECTLYNormal Operation
The rear entertainment module (RETM) routes audio signals to the audio control module (ACM). In single-play mode, the ACM plays the DVD audio on all speakers. In dual-play mode, the audio to the rear speakers is muted and the RETM continues to control the rear audio source to the headphones.
If the vehicle is equipped with satellite audio and/or the SYNC system, the audio signals from these sources are routed through the RETM to the ACM. This allows for single-play and dual-play to include these audio sources.
This pinpoint test is intended to diagnose the following:
- Wiring, terminals or connectors
- RETM
- ACM
