INSPECTION PROCEDURE

PROCEDURE

1. INSPECT RADIO RECEIVER ASSEMBLY




(a) Disconnect the R3 receiver connector.
(b) Measure the resistance of the receiver.
Standard resistance:






NG -- REPLACE RADIO RECEIVER ASSEMBLY
OK -- Continue to next step.
2. CHECK WIRE HARNESS (RADIO RECEIVER - STEREO COMPONENT AMPLIFIER)




(a) Disconnect the R3 receiver connector.
(b) Disconnect the S23 amplifier connector.
(c) Measure the resistance of the wire harness side connectors.
Standard resistance:






NG -- REPAIR OR REPLACE HARNESS AND CONNECTOR
OK -- Continue to next step.
3. INSPECT STEREO COMPONENT AMPLIFIER ASSEMBLY
(a) Temporarily replace the amplifier with a new or normally functioning amplifier.
(b) Turn the ignition switch to ACC and check that the amplifier is functioning properly by operating the radio receiver switches.
OK:
Amplifier can be operated by radio receiver switches.
OK -- END
NG -- Continue to next step.
4. INSPECT RADIO RECEIVER ASSEMBLY
(a) Temporarily replace the radio receiver with a new or normally functioning radio receiver.
(b) Turn the ignition switch to ACC and check that the radio receiver switches are functioning properly.
OK:
Radio receiver switches are functioning properly.
OK -- END
NG -- Continue to next step.
5. CHECK WIRE HARNESS (RADIO RECEIVER - GATEWAY ECU)




(a) Disconnect the R1 receiver connector.
(b) Disconnect the G3 ECU connector.
(c) Measure the resistance of the wire harness side connector.
Standard resistance:






NG -- REPAIR OR REPLACE HARNESS AND CONNECTOR
OK -- PROCEED TO NEXT CIRCUIT INSPECTION SHOWN IN PROBLEM SYMPTOMS TABLE
