INSPECTION PROCEDURE

PROCEDURE

1. INSPECT FUSE (RAD NO. 1, ACC)

(a) Disconnect the RAD NO. 1 fuse from the engine room No. 2 relay block.

(b) Disconnect the ACC fuse from the instrument panel junction block.

(c) Measure the resistance of the fuses.

Standard resistance:

Below 1 Ohms

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

2. CHECK HARNESS AND CONNECTOR (RADIO RECEIVER - BATTERY AND CONNECTOR)

(a) Disconnect the E47 (*2) or E62 (*1) receiver connector.





(b) Measure the voltage and resistance according to the value(s) in the table below.

Standard Voltage:

Standard Resistance










HINT
*1: for Separate Type Amplifier System

*2: for Built-in Type Amplifier System

NG -- REPAIR OR REPLACE HARNESS OR CONNECTOR

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