WIRING DIAGRAM





INSPECTION 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
