Information and Entertainment System

Pinpoint Test K: The SYNC(R) System Is Completely Inoperative (Late Build)

Normal Operation

The APIM (Accessory Protocol Interface Module) takes action based on network message received from the ACM (Audio Front Control Module), and the VOICE switch (part of the steering wheel controls).

- DTC U3000:04 (Control Module: System Internal Failure)- sets when the APIM (Accessory Protocol Interface Module) detects a fault due to a device conflict or an internal failure with the ignition in the RUN or ACC position.

This pinpoint test is intended to diagnose the following:

- Audio system concern

- Communication network concern

- Customer error

- Customer device

- APIM (Accessory Protocol Interface Module)

PINPOINT TEST K : THE SYNC(R) SYSTEM IS COMPLETELY INOPERATIVE (LATE BUILD)

K1 CHECK FOR SCAN TOOL COMMUNICATION WITH THE APIM (Accessory Protocol Interface Module)

- Carry out the network test using the scan tool.

Does the APIM (Accessory Protocol Interface Module) pass the network test?

Yes
GO to K2.

No
REFER to Information Bus.

K2 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 (105-00120).

- Using the Multi-Media Interface Tester (105-00120), test the audio output for the audio input jack, USB (Universal Serial Bus) 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 K3.

K3 RESET THE APIM (Accessory Protocol Interface Module) AND RECHECK SYNC(R) SYSTEM OPERATION

- Carry out an APIM (Accessory Protocol Interface Module) power reset by disconnecting the battery for 5 minutes, then reconnecting it.

- Connect: Multi-Media Interface Tester (105-00120).

- Using the Multi-Media Interface Tester (105-00120), test the audio output for the audio input jack, USB (Universal Serial Bus) 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 System to diagnose the observed symptom. Symptom Related Diagnostic Procedures If all inputs are inoperative and/or DTC U3000:04 is present, INSTALL a new APIM (Accessory Protocol Interface Module).
