Pinpoint Test W: No Auxiliary Headphone Audio

Normal Operation

The Rear Entertainment Module (RETM) sends wireless audio signals to the headphones. 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. When the headphones are set to channel A, all audio sources can be accessed. When the headphones are set to channel B, only the DVD audio and auxiliary audio sources (such as a gaming system) can be sent to the headphones.

This pinpoint test is intended to diagnose the following:

- Customer setting
- Headphone batteries
- Headphones
- RETM
