Headlight Cleaner Motor and Relay Circuit
WIPER AND WASHER SYSTEM: Headlight Cleaner Motor and Relay Circuit
Headlight Cleaner Motor and Relay Circuit
DESCRIPTION
This circuit provides the headlight cleaner control relay with the power circuit.
The headlight cleaner control relay sends the signal to operate from the switch, etc., to the headlight cleaner motor and pump assembly.

INSPECTION PROCEDURE
PROCEDURE
1. INSPECT FUSE
(a) Inspect the H-LP CLN, AM1, ECU-IG No.2 and INP-J/B fuses.
(1) Measure the resistance between each terminal.
Standard resistance:
Below 1 Ohms
NG -- CHECK FOR SHORT IN ALL HARNESS AND COMPONENTS CONNECTED FAILURE FUSE
OK -- Continue to next step.
2. INSPECT RELAY
(a) Inspect IG1 relay continuity.
(1) Measure the resistance according to the value(s) in the table below.
Standard resistance:
NG -- REPLACE RELAY
OK -- Continue to next step.
3. CHECK HARNESS AND CONNECTOR (HEADLIGHT CLEANER CONTROL RELAY - BODY GROUND)
(a) Disconnect the connector from the headlight cleaner relay.
(b) Measure the resistance according to the value(s) in the table below.
Standard resistance:
NG -- REPAIR OR REPLACE HARNESS AND CONNECTOR
OK -- Continue to next step.
4. INSPECT HEADLIGHT CLEANER CONTROL RELAY (POWER SOURCE CIRCUIT)
(a) Measure the voltage according to the value(s) in the table below.
Standard voltage:
NG -- INSPECT IGNITION SWITCH
OK -- Continue to next step.
5. INSPECT HEADLIGHT CLEANER CONTROL RELAY
(a) Reconnect the connector.
(b) Measure the voltage according to the value(s) in the table below.
Standard voltage:
NG -- INSPECT WINDSHIELD WASHER MOTOR AND PUMP ASSEMBLY
OK -- PROCEED TO NEXT CIRCUIT INSPECTION SHOWN IN PROBLEM SYMPTOMS TABLE
6. INSPECT IGNITION SWITCH
(a) Disconnect the connector from the ignition switch.
(b) Measure the resistance according to the value(s) in the table below.
Standard resistance:
NG -- REPLACE IGNITION SWITCH
OK -- REPAIR OR REPLACE HARNESS AND CONNECTOR
7. INSPECT WINDSHIELD WASHER MOTOR AND PUMP ASSEMBLY
(a) Inspect the windshield washer motor and pump assembly.
NG -- REPLACE WINDSHIELD WASHER MOTOR AND PUMP ASSEMBLY
OK -- REPAIR OR REPLACE HARNESS AND CONNECTOR
