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

PINPOINT TEST S: 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 front display interface module (FDIM) display while driving. The ring tone alerts the driver to an incoming call.

Audible prompts can range from 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 an outside device during a phone call, are sent from the accessory protocol interface module (APIM) to the audio control module (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
