INSPECTION PROCEDURE

PROCEDURE

1. INSPECT FUSE (WIP)
(a) Remove the WIP fuse from the instrument panel J/B.
(b) Measure the resistance of the fuse.
Standard resistance:
Below 1 Ohms
NG -- REPLACE FUSE
OK -- Continue to next step.
2. INSPECT IG1 RELAY




(a) Remove the IG1 relay from the instrument panel J/B.
(b) Measure the resistance of the relay.
Standard resistance:






NG -- REPLACE IG1 RELAY
OK -- Continue to next step.
3. CHECK HARNESS AND CONNECTOR (WIPER MOTOR - BATTERY, BODY GROUND)




(a) Disconnect the A50 windshield wiper motor assembly connector.
(b) Measure the voltage according to the value(s) in the table below.
Standard voltage:





(c) Measure the resistance according to the value(s) in the table below.
Standard resistance:






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