Inspection Procedure

WARNING: This page is about a different car, the 2004 Toyota Corolla. However, it is still accessible from the selected car via links, so may be relevant.
  1. CHECK SECURITY INDICATOR LIGHT 
    1. Set the system in 30 seconds after filliping the security indicator to check if the alarm is triggered.
    1. OK: NO PROBLEM 
    2. NG: GO TO NEXT STEP. 
  2. CHECK GLASS BREAKAGE SENSOR ECU (GLASS BREAKAGE SENSOR) 
    1. Check the continuity and voltage of the glass breakage sensor ECU, as shown in the illustration and table.

      Standard: 

      TERMINAL SPECIFIED CONDITION

      Terminal No. Condition Specified condition
      G3-1 <=> Body ground Constant Battery voltage
      G3-3 <=> Body ground Constant Pulse generation
      G3-5 <=> Body ground Constant Continuity
      G3-8 <=> Body ground Ignition switch ON Battery voltage

    1. NG: CHECK AND REPLACE GLASS BREAKAGE SENSOR ECU (See  ELECTRONIC CIRCUIT INSPECTION PROCEDURE  ) 
    2. OK: GO TO NEXT STEP. 
  3. CHECK WIRE HARNESS (TVIP ECU <=> GLASS BREAKAGE SENSOR ECU) 
    1. Disconnect the TVIP ECU and glass breakage sensor ECU connectors.
    2. Check the continuity and between the connectors on the harness side, as shown in the illustration and table.

      Standard: 

      TERMINAL SPECIFIED CONDITION

      Symbols (Terminal No.) (TVIP ECU <=> Sensor ECU) Specified condition
      IOUT (T3-11) <=> IOUT (G3-3) Continuity

    1. NG: REPAIR OR REPLACE WIRE HARNESS AND CONNECTOR 
    2. OK: GO TO NEXT STEP. 
  4. CHECK WIRE HARNESS (GLASS BREAKAGE SENSOR ECU <=> BODY GROUND) 
    1. Disconnect the glass breakage sensor ECU connector.
    2. Check the continuity between the terminal of the glass breakage sensor ECU connector and the body ground, as shown in the illustration and table.

      Standard: 

      TERMINAL SPECIFIED CONDITION

      Symbols (Terminal No.) (Glass breakage sensor <=> Body ground) Specified condition
      GND (G3-6) <=> Body ground Continuity
