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. 2, H-LP CLN)

(a) Remove the ECU-IG No. 2 fuse from the main body ECU.





(b) Remove the H-LP CLN fuse from the engine junction block.

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

Standard Resistance:





(d) Reinstall the ECU-IG No. 2 fuse.

(e) Reinstall the H-LP CLN fuse.

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

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

(a) Disconnect the A32 headlight cleaner control relay 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:





(d) Reconnect the headlight cleaner control relay connector.

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

3. INSPECT HEADLIGHT CLEANER MOTOR AND PUMP ASSEMBLY

(a) Remove the A30 headlight cleaner motor and pump assembly.





(b) Connect the battery positive (+) lead to terminal 1 and the negative (-) lead to terminal 2.

(c) Check that the rear washer motor operates.

OK:

Headlight cleaner motor operates.

(d) Remove the headlight cleaner motor and pump assembly.

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

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

(a) Disconnect the A30 headlight cleaner motor and pump connector.





(b) Disconnect the A32 headlight cleaner 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:





(e) Reconnect the headlight cleaner motor and pump connector.

(f) Reconnect the headlight cleaner control relay connector.

NG -- REPAIR OR REPLACE HARNESS OR CONNECTOR

OK -- PROCEED TO NEXT CIRCUIT INSPECTION SHOWN IN PROBLEM SYMPTOMS TABLE Symptom Related Diagnostic Procedures
