Lexus NX: Data Signal Circuit between Radio Receiver and Stereo Jack Adapter
DESCRIPTION
The No. 1 stereo jack adapter assembly sends the sound data signal or image data signal from a USB device to the radio receiver assembly via this circuit.
WIRING DIAGRAM
PROCEDURE
| 1. | CHECK HARNESS AND CONNECTOR (RADIO RECEIVER ASSEMBLY - NO. 1 STEREO JACK ADAPTER ASSEMBLY) |
| (a) Disconnect the I179 radio receiver assembly connector. |
|
(b) Disconnect the I166 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 |
|---|---|---|
| I179-2 (US1-) - I166-2 (UDO-) | Always | Below 1 Ω |
| I179-3 (US1+) - I166-3 (UDO+) | Always | Below 1 Ω |
| I179-5 (USG1) - I166-5 (UJSS) | Always | Below 1 Ω |
| I179-2 (US1-) or I166-2 (UDO-) - Body ground | Always | 10 kΩ or higher |
| I179-3 (US1+) or I166-3 (UDO+) - Body ground | Always | 10 kΩ or higher |
| I179-5 (USG1) or I166-5 (UJSS) - Body ground | Always | 10 kΩ or higher |
