Lexus ES: Voice Guidance Circuit between Radio Receiver and Stereo Component Amplifier
DESCRIPTION
Using this circuit, the radio receiver assembly sends signals to the stereo component amplifier assembly.
WIRING DIAGRAM
PROCEDURE
| 1. | CHECK HARNESS AND CONNECTOR (RADIO RECEIVER ASSEMBLY - STEREO COMPONENT AMPLIFIER ASSEMBLY) |
(a) Disconnect the G7 radio receiver assembly connector.
(b) Disconnect the G9 stereo component amplifier assembly connector.
(c) Measure the resistance according to the value(s) in the table below.
Standard Resistance:
| Tester connection | Condition | Specified condition |
|---|---|---|
| G7-3 (RL+) - G9-15 (II1+) | Always | Below 1 Ω |
| G7-8 (RL-) - G9-14 (II1-) | Always | Below 1 Ω |
| G9-18 (SLD1) - Body ground | Always | 10 kΩ or higher |
| G7-3 (RL+) or G9-15 (II1+) - Body ground | Always | 10 kΩ or higher |
| G7-8 (RL-) or G9-14 (II1-) - Body ground | Always | 10 kΩ or higher |
| OK |  | PROCEED TO NEXT SUSPECTED AREA SHOWN IN PROBLEM SYMPTOMS TABLE |
