DIAGNOSIS SYSTEM (BLUETOOTH® CONTROL UNIT)

Diagnosis Description

INFOID:0000000009174535

The Bluetooth

®

 control unit has two diagnostic checks. The first diagnostic check is performed automatically

every ignition cycle during control unit initialization. The second diagnostic check is performed by the techni-

cian using the steering wheel audio control switches prior to trouble diagnosis.

Bluetooth

®

 CONTROL UNIT INITIALIZATION CHECKS

• Internal control unit failure
• Bluetooth

®

 antenna connection open or shorted

• Steering wheel audio control switches 

 (PHONE/SEND), 

 (PHONE/END) stuck closed

• Vehicle speed pulse count

• Microphone connection test (with playback to operator)
• Bluetooth

®

 inquiry check

OPERATION PROCEDURE

1. Turn ignition switch to ACC or ON.
2. Wait for the Bluetooth

®

 system to complete initialization. This may take up to 20 seconds.

3. Press and hold the steering wheel audio control switch 

(PHONE/SEND) button for at least 5 seconds. The Bluetooth

®

system will begin to play a verbal prompt.

4. While the prompt is playing, press and hold the steering wheel

audio control switch   (PHONE/END) button until you hear the
“Diagnostics mode” prompt. The Bluetooth

®

 system will sound a

5-second beep.

5. While the beep is sounding, press and hold the steering wheel

audio control switch 

 (PHONE/END) button again until you

hear prompts.

6. The Bluetooth

®

 system has now entered into the diagnostic

mode. Results of the diagnostic checks will be verbalized to the

technician. Refer to 

AV-223, "Work Flow"

.

7. After the failure records are reported, an interactive microphone

test will be performed. Follow the voice prompt. If the microphone test fails, refer to 

AV-223, "Work Flow"

.
