Pinpoint Test G: The Universal Serial Bus (USB) Port Is Inoperative/Does Not Operate Correctly
Normal Operation
The Universal Serial Bus (USB) port is connected to the Accessory Protocol Interface Module (APIM) through the USB (Universal Serial Bus) cable. The USB (Universal Serial Bus) port can be used to play audio files, upload software from mass storage devices or connect a media device.
If supported by the user device, the USB (Universal Serial Bus) port can provide charging. Because of this feature, when a USB (Universal Serial Bus) device is plugged into the USB (Universal Serial Bus) port, the SYNC(R) system does not automatically switch to the device.
If a USB (Universal Serial Bus) mass storage device is used to play an audio file, the SYNC(R) system only plays audio files that do not have Digital Rights Management (DRM) protection.
The USB (Universal Serial Bus) cable and port are not serviceable separately.
- DTC B1252:04 (USB (Universal Serial Bus) Port: System Internal Failure)- sets when the APIM (Accessory Protocol Interface Module) detects any fault in the USB (Universal Serial Bus) circuit. This can be caused by a fault in the USB (Universal Serial Bus) cable or port or by the customer USB (Universal Serial Bus) device.
- DTC B1252:11 (USB (Universal Serial Bus) Port: Circuit Short to Ground)- sets when the APIM (Accessory Protocol Interface Module) detects a short to ground in the USB (Universal Serial Bus) circuit.
This pinpoint test is intended to diagnose the following:
- Customer USB (Universal Serial Bus) device
- USB (Universal Serial Bus) cable and port
- APIM (Accessory Protocol Interface Module)
PINPOINT TEST G : THE USB (Universal Serial Bus) PORT IS INOPERATIVE/DOES NOT OPERATE CORRECTLY
G1 CHECK THE USB (Universal Serial Bus) CONNECTION
- Connect: Multi-Media Interface Tester.
- Using the Multi-Media Interface Tester, attempt to play a file using the USB (Universal Serial Bus) port.
Does the audio file play successfully using the USB (Universal Serial Bus) connection?
Yes
The SYNC(R) system is operating correctly. REVIEW the operation of the USB (Universal Serial Bus) port with the customer. If the customer device still does not operate correctly, the fault is with the customer device.
No
GO to G2.
G2 INSPECT THE USB (Universal Serial Bus) CABLE
- Ignition OFF.
- Disconnect: USB (Universal Serial Bus) Cable (At APIM (Accessory Protocol Interface Module) ).
- Inspect the USB (Universal Serial Bus) cable for damage.
- Connect: USB (Universal Serial Bus) Cable (At APIM (Accessory Protocol Interface Module) ).
- Ignition ON.
- Connect: Multi-Media Interface Tester.
- Using the Multi-Media Interface Tester, attempt to play a file using the USB (Universal Serial Bus) port.
Does the audio file play successfully using the USB (Universal Serial Bus) connection?
Yes
The concern was caused by the USB (Universal Serial Bus) connection not being seated correctly. The system is now operating correctly. CLEAR the DTCs.
No
GO to G3.
G3 RESET THE APIM (Accessory Protocol Interface Module) AND RECHECK 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.
- 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.
- Using the Multi-Media Interface Tester, 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 the USB (Universal Serial Bus) port is inoperative, GO to G4. If additional inputs are inoperative, GO to Symptom Chart - SYNC System to diagnose the observed symptom Symptom Chart - SYNC(R) System. If all inputs are inoperative, INSTALL a new APIM (Accessory Protocol Interface Module). REFER to Accessory Protocol Interface Module (APIM) .
G4 ISOLATE THE USB (Universal Serial Bus) CABLE AND PORT
- Disconnect: Multi-Media Interface Tester.
- Install a new USB (Universal Serial Bus) cable and port. Refer to Universal Serial Bus (USB) Cable and Port .
- Connect: Multi-Media Interface Tester.
- Using the Multi-Media Interface Tester, attempt to play a file using the USB (Universal Serial Bus) port.
Does the audio file play successfully using the USB (Universal Serial Bus) connection?
Yes
The concern was caused by an inoperative USB (Universal Serial Bus) cable. The system is now operating correctly. CLEAR the DTCs.
No
GO to G5.
G5 CHECK FOR CORRECT APIM (Accessory Protocol Interface Module) OPERATION
- Disconnect the APIM (Accessory Protocol Interface Module) connector.
- Check for:
- corrosion
- damaged pins
- pushed-out pins
- Connect the APIM (Accessory Protocol Interface Module) connector and make sure it seats correctly.
- Wait 2 minutes for the APIM (Accessory Protocol Interface Module) to re-initialize.
- Operate the system and verify the concern is still present.
Is the concern still present?
Yes
INSTALL a new APIM (Accessory Protocol Interface Module). REFER to Accessory Protocol Interface Module (APIM) . TEST the system for normal operation.
No
The system is operating correctly at this time. The concern may have been caused by a loose or corroded connector. CLEAR the DTCs.
