Intrusion Sensor Cancel Switch Circuit

THEFT DETERRENT: THEFT DETERRENT SYSTEM: Intrusion Sensor Cancel Switch Circuit
- Intrusion Sensor Cancel Switch Circuit

DESCRIPTION

* When the intrusion sensor cancel switch on the instrument panel control and panel assembly is pressed, the sensor off signal is sent to the multiplex network body ECU, which causes the intrusion sensor to stop operating.

WIRING DIAGRAM







PROCEDURE

1. CHECK HARNESS AND CONNECTOR (INTRUSION SENSOR CANCEL SWITCH - MULTIPLEX NETWORK BODY ECU)





(a) Disconnect the K12 control and panel assembly connector.

(b) Disconnect the K68 ECU connector.

(c) Measure the resistance of the wire harness side connectors.

Standard resistance:





NG -- REPAIR OR REPLACE HARNESS OR CONNECTOR
OK -- Continue to next step.

2. CHECK OPERATION OF INTRUSION SENSOR CANCEL SWITCH

(a) Temporarily replace the instrument control and panel assembly (intrusion sensor cancel switch) with a new or normally functioning one.

(b) Turn the intrusion sensor off by pressing the intrusion sensor cancel switch. Check if the switch operates normally by checking that the theft deterrent system does not operate when you move your hand in front of the sensor.

OK:

Intrusion sensor cancel switch operates normally.

NG -- REPLACE COWL SIDE JUNCTION BLOCK RH (MULTIPLEX NETWORK BODY ECU)

OK -- END (INSTRUMENT CONTROL AND PANEL ASSEMBLY (INTRUSION SENSOR CANCEL SWITCH) WAS DEFECTIVE)
