Test O: The Voice Guidance Is Inoperative/Does Not Operate Correctly

PINPOINT TEST O: THE VOICE GUIDANCE IS INOPERATIVE/DOES NOT OPERATE CORRECTLY

Normal Operation
The voice guidance settings are controlled by the audio control module (ACM). The voice guidance volume can be adjusted or turned off depending on user preference.

For the THX(R) audio system, the ACM sends the voice guidance signal to the audio digital signal processing (DSP) module through circuits VME22 (VT/GN) and RME22 (GN/WH).

This pinpoint test is intended to diagnose the following:
- Incorrect system setting
- Wiring, terminals or connectors (THX(R) only)
- DSP module (if equipped)
- ACM
