Lexus NX: Sound Signal Circuit between Radio Receiver and Stereo Jack Adapter
DESCRIPTION
The No. 1 stereo jack adapter assembly sends the sound signal from an external device to the radio receiver assembly via this circuit.
The sound signal that has been sent is amplified by the stereo component amplifier assembly and then is sent to the speakers.
If there is an open or short in the circuit, sound cannot be heard from the speakers even if there is no malfunction in the stereo component amplifier assembly, radio receiver assembly or speakers.
WIRING DIAGRAM
PROCEDURE
| 1. | CHECK HARNESS AND CONNECTOR (RADIO RECEIVER ASSEMBLY - NO. 1 STEREO JACK ADAPTER ASSEMBLY) |
(a) Disconnect the I151 radio receiver assembly connector.
(b) Disconnect the I155 No. 1 stereo jack adapter assembly connector.
(c) Measure the resistance according to the value(s) in the table below.
Standard Resistance:
| Tester Connection | Condition | Specified Condition |
|---|---|---|
| I151-14 (ADPG) - I155-2 (ADPG) | Always | Below 1 Ω |
| I151-10 (AGND) - I155-7 (AGND) | Always | Below 1 Ω |
| I151-11 (VAL+) - I155-1 (VAL+) | Always | Below 1 Ω |
| I151-12 (VAR+) - I155-6 (VAR+) | Always | Below 1 Ω |
| I151-13 (VA-) - I155-5 (VA-) | Always | Below 1 Ω |
| I151-14 (ADPG) or I155-2 (ADPG) - Body ground | Always | 10 kΩ or higher |
| I151-10 (AGND) or I155-7 (AGND) - Body ground | Always | 10 kΩ or higher |
| I151-11 (VAL+) or I155-1 (VAL+) - Body ground | Always | 10 kΩ or higher |
| I151-12 (VAR+) or I155-6 (VAR+) - Body ground | Always | 10 kΩ or higher |
| I151-13 (VA-) or I155-5 (VA-) - Body ground | Always | 10 kΩ or higher |
