Microphone Circuit between Microphone and Navigation Receiver Assembly |
DESCRIPTION
w/o Safety Connect System:
The navigation receiver assembly and amplifier microphone assembly are connected to each other using the microphone connection detection signal lines.
Using this circuit, the navigation receiver assembly sends power to the amplifier microphone assembly, and the amplifier microphone assembly sends microphone signals to the navigation receiver assembly.
w/ Safety Connect System:
The navigation receiver assembly and amplifier microphone assembly are connected to each other using the microphone connection detection signal lines.
Using this circuit, the DCM (telematics transceiver) sends power to the amplifier microphone assembly, and the amplifier microphone assembly sends microphone signals to the navigation receiver assembly via the DCM (telematics transceiver).
WIRING DIAGRAM
CAUTION / NOTICE / HINT
NOTICE:
If the DCM (telematics transceiver) has been replaced, perform the DCM Activation procedure using the Techstream (w/ Safety Connect System) (See page
![2016 MY Sienna [12/2015 - 08/2016]; INTRODUCTION: REPAIR INSTRUCTION: INITIALIZATION](/t3Portal/stylegraphics/info.gif)
).
PROCEDURE
|
1. |
CHECK MICROPHONE (OPERATION CHECK) |
|
(a) Enter the "Microphone Check" screen. Refer to Check Microphone in Operation Check (See page
|
|
(b) When a voice is input into the microphone, check that the microphone input level meter changes according to the input voice.
(c) Push the recording switch and perform voice recording.
HINT:
- Select the recording switch with the blower motor of the air conditioning system stopped. If an outlet of the air conditioning system is facing the microphone, noise may be recorded.
- Voice can be recorded for up to 5 seconds.
(d) Check that the recording indicator remains on while recording and that the recorded voice is played normally without noise or distortion.
OK:
All check results are normal.
