Pinpoint Test V: The SYNC System Is Completely Inoperative

Normal Operation

The Accessory Protocol Interface Module (APIM) receives voltage at all times from circuit SBP03 (BU/RD), and ground through circuit GD115 (BK/GY). The APIM communicates via the Medium Speed Controller Area Network (MS-CAN).

When a button on the Front Controls Interface Module (FCIM) (vehicles without navigation) or Audio Control Module (ACM) (vehicles with navigation) is pressed, a network message is sent to the APIM via the MS-CAN. The APIM takes the appropriate action and sends a status message to the Front Display Interface Module (FDIM) (vehicles without navigation) or the ACM (vehicles with navigation) in order to update the display screen.

- Communication network concern
- Customer error
- APIM
- ACM



PINPOINT TEST V: THE SYNC SYSTEM IS COMPLETELY INOPERATIVE

-------------------------------------------------
V1 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 V2.

No
REFER to Information Bus.

-------------------------------------------------
V2 CHECK THE SYNC SYSTEM OPERATION


NOTE: Carrying out a Master Reset returns all preference settings to the factory defaults, erases all the phone book and call histories, and deletes any devices paired with the SYNC system.

- Connect: Multi-Media Interface Tester.
- Using the Multi-Media Interface Tester, test the audio output for the audio input jack, USB port, and Bluetooth connection.
- 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 SYNC system operation with the customer. If the customer device still does not operate correctly, 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 Chart - SYNC System

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