DIAGNOSIS SYSTEM (BLUETOOTH CONTROL UNIT)
Diagnosis Description
INFOID:0000000006166573
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.
3. Press and hold the steering wheel audio control switch
button for at least 5 seconds. The Bluetooth system will begin to
