THEFT DETERRENT SYSTEM Glass Breakage Sensor Circuit

DESCRIPTION

When the main body ECU (multiplex network body ECU) detects that a glass breakage sensor (quarter window assembly RH, quarter window assembly LH or back window glass) is broken, the theft deterrent system switches from the armed state to the alarm sounding state.

  5. CHECK HARNESS AND CONNECTOR (MAIN BODY ECU (MULTIPLEX NETWORK BODY ECU - GLASS BREAKAGE SENSOR (QUARTER WINDOW ASSEMBLY RH))


    1. Disconnect the O2 main body ECU (multiplex network body ECU) connector.

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

      Standard Resistance
      Tester Connection Condition Specified Condition
      O2-7 (GPBS) - T30-1 (SSR+) Always Below 1 Ω
      O2-7 (GPBS) or T30-1 (SSR+) - Body ground Always 10 kΩ or higher
      Result
      Proceed to
      OK
      NG

    NG

    REPAIR OR REPLACE HARNESS OR CONNECTOR

    OK

  6. CHECK HARNESS AND CONNECTOR (GLASS BREAKAGE SENSOR (QUARTER WINDOW ASSEMBLY RH) - GLASS BREAKAGE SENSOR (QUARTER WINDOW ASSEMBLY LH))


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

      Standard Resistance
      Tester Connection Condition Specified Condition
      T30-2 (SSR-) - U52-1 (SSR+) Always Below 1 Ω
      T30-2 (SSR-) or U52-1 (SSR+) - Body ground Always 10 kΩ or higher
      Result
      Proceed to
      OK
      NG

    NG

    REPAIR OR REPLACE HARNESS OR CONNECTOR

    OK

  7. CHECK HARNESS AND CONNECTOR (GLASS BREAKAGE SENSOR (QUARTER WINDOW ASSEMBLY LH) - GLASS BREAKAGE SENSOR (BACK WINDOW GLASS) - BODY GROUND)


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

      Standard Resistance
      Tester Connection Condition Specified Condition
      U52-2 (SSR-) - YU1-1 (SSR+) Always Below 1 Ω
      U52-2 (SSR-) or YU1-1 (SSR+) - Body ground Always 10 kΩ or higher
