OPERATION PROCEDURE

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

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-27, "Work Flow"

.

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

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