DIAGNOSIS SYSTEM (BLU ETOOTH® CONTROL UNIT)
Diagnosis DescriptionINFOID:0000000012432873
The Bluetooth® control unit has two diagnostic checks. The fi rst 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-17, "
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-17, "
Work Flow".
