Headlight Cleaner Motor and Relay Circuit

WIPER / WASHER: WIPER AND WASHER SYSTEM: Headlight Cleaner Motor and Relay Circuit
- Headlight Cleaner Motor and Relay Circuit

DESCRIPTION

This circuit provides power to the headlight cleaner control relay.

The headlight cleaner control relay sends the signal from the switch, etc. to the headlight cleaner motor to operate the headlight cleaner system.

INSPECTION PROCEDURE

PROCEDURE

1. INSPECT FUSE (ECU-IG No. 1, H-LP CLR)

(a) Remove the ECU-IG No. 1 fuse from the cowl side junction block LH.

(b) Remove the H-LP CLR fuse from the engine relay block.

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

Standard Resistance:

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

2. CHECK HARNESS AND CONNECTOR (HEADLIGHT CLEANER CONTROL RELAY - BATTERY AND BODY GROUND)

(a) Disconnect the relay connector.

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

Standard Voltage:

NG -- REPAIR OR REPLACE HARNESS OR CONNECTOR
OK -- Continue to next step.

3. INSPECT HEADLIGHT CLEANER MOTOR AND PUMP ASSEMBLY

(a) Remove the headlight cleaner motor Removal.

(b) Apply battery voltage to the headlight cleaner motor connector and check the operation of the headlight cleaner motor.

OK:

NG -- REPLACE HEADLIGHT CLEANER MOTOR AND PUMP ASSEMBLY Removal
OK -- Continue to next step.

4. CHECK HARNESS AND CONNECTOR (CLEANER MOTOR - CONTROL RELAY AND BATTERY)

(a) Disconnect the cleaner motor connector.

(b) Disconnect the control relay connector.

(c) Measure the voltage according to the value(s) in the table below.

Standard Voltage:

(d) 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 Symptom Related Diagnostic Procedures
