THEFT DETERRENT SYSTEM Intrusion Sensor Cancel Switch Circuit

DESCRIPTION

• When the intrusion sensor cancel switch on the map light assembly is pressed, the sensor off signal is sent to the main body ECU (multiplex network body ECU) which causes the intrusion sensor (theft warning radar sensor) to stop operating.

INSPECTION PROCEDURE

PROCEDURE

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

   
   

   1. Connect the intelligent tester to the DLC3.

   2. Turn the power switch on (IG).

   3. Turn the intelligent tester on.

   4. Enter the following menus: Body / Main Body / Data List.

   5. According to the display on the intelligent tester, perform the Active Test.

      Main Body (Main Body ECU (Multiplex Network Body ECU))

      Tester Display	Measurement Item/Range	Normal Condition	Diagnostic Note
      Intrusion Sens OFF SW	Intrusion sensor cancel switch/ON or OFF	ON: Intrusion sensor cancel switch on OFF: Intrusion sensor cancel switch off	-

      OK
      The indicator on the intelligent tester switches between ON and OFF in accordance with the intrusion sensor cancel switch status.

2. CHECK HARNESS AND CONNECTOR (MAIN BODY ECU - MAP LIGHT ASSEMBLY)

   
   

   1. Disconnect the E121 main body ECU (multiplex network body ECU) and O8 map light assembly connectors.

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

      Standard Resistance
      Tester Connection Condition Specified Condition E121-8 (SSW1) - O8-2 (SOFF) Always Below 1 Ω O8-7 (GND) - Body ground Always Below 1 Ω E121-8 (SSW1) - Body ground Always 10 kΩ or higher

   
   

   NG

   REPAIR OR REPLACE HARNESS OR CONNECTOR

   OK

3. INSPECT INTRUSION SENSOR CANCEL SWITCH

   
   
   1.
