PROCEDURE


  1. READ VALUE USING INTELLIGENT TESTER (GLASS BREAKAGE SENSOR)


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

      Main Body
      Tester Display Measurement Item/Range Normal Condition Diagnostic Note
      Sealed Glas Brak Sen Glass breakage sensor detection / ON or OFF

      ON: Glass breakage sensor operates

      OFF: Glass breakage sensor does not operate

      		 -
      OK
      ON (glass breakage sensor operates) appears on screen.

    OK

    REPLACE MAIN BODY ECU (INSTRUMENT PANEL JUNCTION BLOCK)

    NG

  2. CHECK HARNESS AND CONNECTOR (MAIN BODY ECU [INSTRUMENT PANEL JUNCTION BLOCK] - GLASS BREAKAGE SENSOR)

    A004RT4E02

    1. Disconnect the D81 ECU connector.

    2. Disconnect the H23, G45 and M13 sensor connector.

    3. Disconnect the M7 defogger connector.

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

      Standard Resistance
      Tester Connection Condition Specified Condition
      D81-8 (GBS) - H23-2 (SSR+) Always Below 1 Ω
      H23-1 (SSR-) - G45-2 (SSR+) Always Below 1 Ω
      G45-1 (SSR-) - M13-2 (SSR+) Always Below 1 Ω
      M7-1 - Body ground Always Below 1 Ω
