WIRING DIAGRAM





INSEPCTION PROCEDURE

PROCEDURE

1. INSPECT FUSE (RADIO NO. 1, RADIO NO. 2, AM1)

(a) Remove the RADIO NO. 1 fuse from the engine room No. 1 relay block.

(b) Remove the RADIO NO. 2 fuse from the passenger side junction block.

(c) Remove the AM1 fuse from the driver side junction block.

(d) Measure the resistance of the fuses.

Standard resistance:

Below 1 Ohms

NG -- REPLACE FUSE
OK -- Continue to next step.

2. CHECK WIRE HARNESS (STEREO COMPONENT AMPLIFIER - BATTERY AND BODY GROUND)

(a) Disconnect the S22 and S23 amplifier connectors.





(b) Measure the resistance and voltage of the wire harness side connectors.

Standard resistance:

Standard voltage










NG -- REPAIR OR REPLACE HARNESS AND CONNECTOR

OK -- PROCEED TO NEXT CIRCUIT INSPECTION SHOWN IN PROBLEM SYMPTOMS TABLE
