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


    E064835

  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)


    I036792E01

  1. Disconnect the connector from the headlight cleaner relay.

  1. 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)


    I036792E02

  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


    I036792E03

  1. Reconnect the connector.

  1. 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

6.INSPECT IGNITION SWITCH


    E068971E03

  1. Disconnect the connector from the ignition switch.

  1. 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
