   READ VALUE USING INTELLIGENT TESTER

   
   

   1. Connect the intelligent tester to the DLC3.

   2. Turn the power switch on (IG).

   3. Turn the intelligent tester on.

   4. Select the item below in the Data List and read the display on the intelligent tester.

      Table 1. 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.
