Test V: The SYNC System Audible Prompts Are Inoperative/Do Not Operate Correctly

PINPOINT TEST V: THE SYNC SYSTEM AUDIBLE PROMPTS ARE INOPERATIVE/DO NOT OPERATE CORRECTLY

Normal Operation
The text-to-speech (TTS) and voice prompt features speak certain text information and interaction requests in order to minimize driver distraction by having to look at the audio control module (ACM) while driving. The ring tone alerts the driver to an incoming call.

Audible prompts can range form a simple tone to more elaborate spoken text, based on the customer setting. When interaction mode is set to standard, detailed guidance is provided. When interaction mode is set to advanced, most prompts are tones only and minimal audible guidance is provided. Refer to the Owner's Literature for further information on voice interaction.

The audio signals for the TTS and voice prompt features, the ring tones, and audio from the outside device during a phone call, are sent from a accessory protocol interface module (APIM) to the ACM through circuits VMN14 (WH/VT) and RMN14 (GY/BN).

This pinpoint test is intended to diagnose the following:
- Customer setting
- Wiring, terminals or connectors
- ACM
- APIM
