Pinpoint Test R: The SYNC System Is Completely Inoperative

Normal Operation

The Accessory Protocol Interface Module (APIM) receives voltage at all times from circuit SBB13 (GY/RD), and ground through circuit GD148 (BK/YE). The wake-up signal is sent to the APIM by the Audio Control Module (ACM) via the Medium Speed Controller Area Network (MS-CAN).

If a USB mass storage device is used to play an audio file, the SYNC system only plays audio files that do not have Digital Rights Management (DRM) protection.

-------------------------------------------------
R1 CHECK FOR SCAN TOOL COMMUNICATION WITH THE APIM


- Carry out the network test using the scan tool.
- Does the APIM pass the network test?

Yes
GO to R2.

R2 CHECK THE SYNC SYSTEM OPERATION


NOTE: Carrying out a Master Reset will return all preference settings to the factory defaults, erase all the phone book and call histories and delete any devices paired with the SYNC system.

- Connect: Known Good MP3 Device (To Audio Input Jack).
- Using the Multi-Media Interface Tester, attempt to play a file using the audio input jack, the USB port, and Bluetooth.
- Using a known good MP3 device or mass storage device, attempt to play an audio file using the USB port. Refer to the Owner's Literature.
- Do all of the SYNC inputs function correctly?

Yes
The SYNC system is operating correctly at this time. CARRY OUT a SYNC system Master Reset. REFER to the Owner's Literature.

REVIEW the pairing process with the customer. If the customer device still does not pair, the fault is with the customer device.

No
If only some of the inputs are inoperative, GO to Symptom Chart - SYNC System to diagnose the observed symptom. Symptom Related Diagnostic Procedures

If all inputs are inoperative, Go To Pinpoint Test U. Pinpoint Test U: Poor Quality/Distorted/No Sound While In SYNC Mode
