Diagnostic Instructions

* Perform the Diagnostic System Check - Vehicle Diagnostic System Check - Vehicle prior to using this diagnostic procedure.

* Review Strategy Based Diagnosis Strategy Based Diagnosis for an overview of the diagnostic approach.

* Diagnostic Procedure Instructions Diagnostic Procedure Instructions provide an overview of each diagnostic category.

Circuit/System Description

Bluetooth (R) wireless technology is a short-range communications technology intended to replace the cables connecting portable and/or fixed devices while maintaining high levels of security. The operating range of the signal is approximately 30 feet.

The available features and functions are determined by the type of device and the software within the devices being used. For a feature or function to operate, it must be supported in both devices.

The Bluetooth (R) hardware is internal to the radio. The radio supports streaming of data (music, voice, information) from cellular phones and other mobile devices that support those features. The radio may also be capable of interfacing with cellular phones for hands-free features.

Refer to the vehicle owners manual, supplements, and the device manufacturers information for information on devices, control, operation. and pairing instructions.

Diagnostic Aids

* Verify the mobile device is properly configured for the feature being used. Refer to the device manufacturers information.

* Verify the function/feature that is being used is supported by the mobile device.

* The device must be paired to the radio to use the available Bluetooth (R) feature(s). The pairing process must only be performed once for each device, unless that device's information is deleted.

* The system can store pairing information for multiple devices, but can only be actively connected to one at any given time.

Special Tools

EL-50334-20 - Multi-Media Interface Tester (MIT)

Circuit/System Verification

1. Verify no DTCs are present.

• If any DTCs are present
Refer to Diagnostic Trouble Code (DTC) List - Vehicle Diagnostic Trouble Code (DTC) List - Vehicle.

• If no DTCs are present

2. Verify the radio calibrations are current.

• If the radio calibrations are not current
Reprogram the radio and re-evaluate the concern.

• If no update calibrations are available

Note: The MIT tool can be used to test either cellular phone or streaming audio functions. Refer to the tool instructions, and perform the appropriate test(s) related to the customers concern in the following steps.

3. Ignition ON, infotainment system ON.

4. Verify the infotainment system successfully pairs with the MIT tool.

• If the infotainment system does not successfully pair with the MIT tool.
Replace the A11 radio.

• If the infotainment system successfully pairs with the MIT tool.

5. Verify the infotainment system successfully completes the desired feature test using the MIT tool.

• If the feature test is not successful
Replace the A11 radio.

• If the feature test is successful

6. All OK. Refer to Diagnostic Aids.
