INSPECTION PROCEDURE

1. INSPECT FUSE

1. 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 Ω
      

NG	CHECK FOR SHORT IN ALL HARNESS AND COMPONENTS CONNECTED FAILURE FUSE

OK

2. INSPECT RELAY

1. Inspect IG1 relay continuity.

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

      Standard resistance:

      Terminal No.	Specified Condition
      3 - 5	10 kΩ or higher
      	Below 1 Ω (When battery voltage is applied to terminal 1 and 2)

NG	REPLACE RELAY

OK

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

1. Disconnect the connector from the headlight cleaner relay.

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

   Standard resistance:

   Tester Connection	Condition	Specified Condition
   E - Body ground	Always	Below 1 Ω

NG	REPAIR OR REPLACE HARNESS AND CONNECTOR

OK

4. INSPECT HEADLIGHT CLEANER CONTROL RELAY (POWER SOURCE CIRCUIT)

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

   Standard voltage:

   Tester Connection	Condition	Specified Condition
   IG - Body ground	Ignition switch OFF → ON	Below 1 V → 10 to 14 V

NG	Go to step 6

OK

5. INSPECT HEADLIGHT CLEANER CONTROL RELAY

1. Reconnect the connector.

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

   Standard voltage:

   Tester Connection	Condition	Specified Condition
   PB - Body ground	Ignition switch ON	10 to 14 V

NG	Go to step 7

OK
PROCEED TO NEXT CIRCUIT INSPECTION SHOWN IN PROBLEM SYMPTOMS TABLE

6. INSPECT IGNITION SWITCH

1. Disconnect the connector from the ignition switch.

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

   Standard resistance:

   Tester Connection	Condition	Specified Condition
   AM1 - IG1	Ignition switch OFF → ON	10 kΩ or higher → Below 1 Ω

NG	REPLACE IGNITION SWITCH

OK
REPAIR OR REPLACE HARNESS AND CONNECTOR

7. INSPECT WINDSHIELD WASHER MOTOR AND PUMP ASSEMBLY

1. Inspect the windshield washer motor and pump assembly.

NG	REPLACE WINDSHIELD WASHER MOTOR AND PUMP ASSEMBLY

OK
REPAIR OR REPLACE HARNESS AND CONNECTOR
