WIRING DIAGRAM

A01ERZEE06

INSPECTION PROCEDURE

Note

If the certification ECU (smart key ECU assembly) is replaced, refer to the Service Bulletin.

PROCEDURE


  1. READ VALUE USING INTELLIGENT TESTER (INTRUSION SENSOR CANCEL SWITCH)


    1. Using the intelligent tester, read the Data List.

      Entry&Start
      Tester Display Measurement Item / Display (Range) Normal Condition Diagnostic Note
      Intrusion sensor OFF

      Intrusion sensor cancel switch /

      ON or OFF

      ON: Intrusion sensor active (switch off)

      OFF: Intrusion sensor not active (switch on)

      		 -
      OK
      ON (intrusion sensor active [switch off]) appears on screen.

    NG

    CHECK HARNESS AND CONNECTOR (CERTIFICATION ECU [SMART KEY ECU ASSEMBLY] - MAP LIGHT ASSEMBLY) Click here

    OK

    REPLACE CERTIFICATION ECU (SMART KEY ECU ASSEMBLY)

  2. CHECK HARNESS AND CONNECTOR (CERTIFICATION ECU [SMART KEY ECU ASSEMBLY] - MAP LIGHT ASSEMBLY)


    1. Disconnect the E30 certification ECU (smart key ECU assembly) connector.

    2. Disconnect the R7 map light assembly connector.

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

      Standard Resistance
      Tester Connection Condition Specified Condition
      E30-5 (SSW1) - R7-29 (SOFF) Always Below 1 Ω
      E30-5 (SSW1) or R7-29 (SOFF) - Body ground Always 10 kΩ or higher

    NG

    REPAIR OR REPLACE HARNESS OR CONNECTOR

    OK

  3. CHECK MAP LIGHT ASSEMBLY (INTRUSION SENSOR CANCEL SWITCH [OPERATION])


    1. Temporarily replace the map light assembly (intrusion sensor cancel switch) with a new or normally functioning one Click here.

    2. Turn the intrusion sensor off by pressing the intrusion sensor cancel switch. Check if the switch operates normally by checking that the theft deterrent system does not operate when you move your hand in front of the sensor.

      OK
      Intrusion sensor cancel switch operates normally.

    NG

    REPLACE CERTIFICATION ECU (SMART KEY ECU ASSEMBLY)

    OK

    END (MAP LIGHT [INTRUSION SENSOR CANCEL SWITCH] WAS DEFECTIVE)
