Inspection Procedure

1. Set the system in 30 seconds after filliping the security indicator to check if the alarm is triggered.

OK: NO PROBLEM 

NG 

1. Check the continuity and voltage of the glass breakage sensor ECU.

   Standard: 

   GLASS BREAKAGE SENSOR ECU VOLTAGE & CONTINUITY CHECK
   
   

   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

NG: CHECK AND REPLACE GLASS BREAKAGE SENSOR ECU 

OK: Go to next step 

1. Disconnect the TVIP ECU and glass breakage sensor ECU connectors.
2. Check the continuity and between the connectors on the harness side.

   Standard: 

   WIRE HARNESS (TVIP ECU <=> GLASS BREAKAGE SENSOR ECU) CONTINUITY CHECK
   
   

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

NG: REPAIR OR REPLACE WIRE HARNESS AND CONNECTOR 

OK: Go to next step 

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.

   Standard: 

   WIRE HARNESS (GLASS BREAKAGE SENSOR ECU <=> BODY GROUND) CONTINUITY CHECK
   
   

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