Information and Entertainment System

Pinpoint Test Z: The SYNC(R) System Is Completely Inoperative

Normal Operation

When a button on the Front Controls Interface Module (FCIM) is pressed, a network message is sent to the Accessory Protocol Interface Module (APIM) via the Medium Speed Controller Area Network (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 Audio Control Module (ACM) (vehicles with navigation) in order to update the display screen.

- DTC U3000:04 (Control Module: System Internal Failure) - sets when the APIM detects a fault due to a device conflict or an internal failure.

This pinpoint test is intended to diagnose the following:

- Audio system concern
- Communication network concern
- Customer error
- Customer device
- APIM


PINPOINT TEST Z: THE SYNC(R) SYSTEM IS COMPLETELY INOPERATIVE

-------------------------------------------------
Z1 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 Z2.

No
REFER to Module Communications Network Testing and Inspection.

-------------------------------------------------
Z2 CHECK THE SYNC(R) 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(R) 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 using the VOICE switch on the steering wheel controls to enter each mode.
- Do all of the SYNC(R) inputs function correctly?

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

REVIEW the SYNC(R) system operation with the customer. If the customer device still does not operate correctly, the fault is with the customer device.

No
GO to Z3.

-------------------------------------------------
Z3 RESET THE APIM AND RECHECK SYNC(R) SYSTEM OPERATION

- Carry out an APIM power reset by disconnecting the battery for 5 minutes, then reconnecting it.
- 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 using the VOICE switch on the steering wheel controls to enter each mode.
- Do all of the SYNC(R) inputs function correctly?

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

REVIEW the SYNC(R) 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 (but not all) of the inputs are inoperative, GO to Symptom Chart - SYNC(R)System to diagnose the observed symptom. If all inputs are inoperative and/or DTC U3000:04 is present, INSTALL a new APIM. REFER to Accessory Protocol Interface Module (APIM) Accessory Protocol Interface Module (APIM).
