Bluetooth Control Unit Self-Diagnosis FunctionEKS00I9J
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

Bluetooth Microphone connection test (with playback to operator)

Bluetooth inquiry check
SELF-DIAGNOSIS MODE
1. Turn ignition switch to ACC or ON.
2. Wait for the Bluetooth system to complete initialization and the Bluetooth ON indicator to stop flashing.
This may take up to 10 seconds.
3. Press and hold the steering wheel audio control switch SEND
button for at least 5 seconds. The Bluetooth system will begin to
play a verbal prompt.
4. While the prompt is playing, momentarily press both the steering
wheel audio control switches SEND and END buttons simulta-
neously. The Bluetooth system will sound a 5 second beep.
5. While the beep is sounding, momentarily press both the steering
wheel audio control switches SEND and END buttons simulta-
neously again.
6. The Bluetooth system has now entered into the diagnostic
mode. Results of the diagnostic checks will be verbalized to the
technician and the Bluetooth ON indicator will flash. Refer to AV-
57, "Workflow" .
7. If there are no failure records to report, the speed pulse count
will be reported next.
8. After the speed pulse count is reported, an interactive Bluetooth microphone test will be performed. Fol-
low the voice prompt. If the Bluetooth microphone test fails refer to AV- 5 7 , "
Workflow" .
9. Self-diagnosis mode is complete when the voice prompt says "All diagnostic functions completed". A short
beep is heard.
