Toyota Camry (XV70): Sound Signal Circuit between Radio Receiver and Stereo Component Amplifier
DESCRIPTION
The radio and display receiver assembly sends a sound signal to the stereo component amplifier assembly via this circuit.
The sound signal that is sent is amplified by the stereo component amplifier assembly, and then is sent to the speakers.
If there is an open or short in this circuit, sound cannot be heard from the speakers even if the stereo component amplifier assembly or speakers are not malfunctioning.

PROCEDURE
| 1. |
CHECK HARNESS AND CONNECTOR (RADIO AND DISPLAY RECEIVER ASSEMBLY - STEREO COMPONENT AMPLIFIER ASSEMBLY) |
(a) Disconnect the K4 radio and display receiver assembly connector.
(b) Disconnect the K10 stereo component amplifier assembly connector.
(c) Measure the resistance according to the value(s) in the table below.
Standard Resistance:

Always | Below 1 Ω |
|
K10-3 (L+) - K4-2 (FL+) |
Always | Below 1 Ω |
|
K10-2 (L-) - K4-7 (FL-) |
Always | Below 1 Ω |
|
K10-6 (SLD) - Body ground |
Always | 10 kΩ or higher |
|
K10-5 (R+) or K4-1 (FR+) - Body ground |
Always | 10 kΩ or higher |
|
K10-4 (R-) or K4-6 (FR-) - Body ground |
Always | 10 kΩ or higher |
|
K10-3 (L+) or K4-2 (FL+) - Body ground |
Always | 10 kΩ or higher |
|
K10-2 (L-) or K4-7 (FL-) - Body ground |

Mute Signal Circuit between Radio Receiver and Stereo Component Amplifier
DESCRIPTION This circuit sends a signal to the stereo component amplifier assembly to mute noise. Because of that, the noise produced by changing the sound source ceases.

Mute Signal Circuit between Stereo Component Amplifier and Telematics Transceiver
DESCRIPTION The DCM (telematics transceiver) sends a mute signal to the stereo component amplifier assembly.
The stereo component amplifier assembly controls the volume according to the mute signal

wipers
When the windshield wipers are not being used, they retract to below
the hood. To enable the windshield wipers to be lifted when parking in
cold conditions or when replacing a windshield wiper insert, change
the rest position of the windshield wipers to the service position using
the wiper lever
