DIAGNOSIS SYSTEM (BLUETOOTH CONTROL UNIT)

Diagnosis Description

INFOID:0000000006706832

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 [SEND(

)/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 10 seconds.

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   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   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-48, "Work Flow"

.

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

test will be performed. Follow the voice prompt. If the micro-

phone test fails refer to 

AV-48, "Work Flow"

.

8. Self-diagnosis mode is complete when the voice prompt says “All diagnostic functions completed”.
