Test P: Voice Recognition Is Inoperative/Does Not Operate Correctly

PINPOINT TEST P: VOICE RECOGNITION IS INOPERATIVE/DOES NOT OPERATE CORRECTLY

Normal Operation
When the VOICE switch is pressed, a signal is sent to the audio control module (ACM) through circuit VME54 (BU/OG), and the ACM enters voice recognition mode. A microphone located in the interior rear view mirror receives the voice command and sends a signal to the ACM through circuits VMM13 (YE/GN) and RMM13 (BU). Power to the interior rear view mirror is provided through circuit CBP02 (GN), and ground through circuit GD139 (BK/YE).

- DTC B2633 (Driver-Front Microphone Circuit Failure) - sets when an open, short to ground, or short to voltage is detected on the microphone circuits.

This pinpoint test is intended to diagnose the following:
- Fuse
- Wiring, terminals or connectors
- Steering wheel controls
- Microphone (part of the interior rear view mirror)
- ACM
