DESCRIPTION
This circuit is used when the voice switch of the steering pad switch assembly is pushed.
Using this circuit, the radio and display 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 I154 radio and display receiver assembly connector.
(b) Disconnect the P46 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 |
|---|---|---|
| I154-3 (RL+) - P46-15 (II1+) | Always | Below 1 Ω |
| I154-8 (RL-) - P46-14 (II1-) | Always | Below 1 Ω |
| P46-18 (SLD1) - Body ground | Always | 10 kΩ or higher |
| I154-3 (RL+) or P46-15 (II1+) - Body ground | Always | 10 kΩ or higher |
| I154-8 (RL-) or P46-14 (II1-) - Body ground | Always | 10 kΩ or higher |
