: CHECK THE SUPPLIES AND GROUNDS TO THE INTRUSION SENSOR

G239843t92 : CHECK THE POWER SUPPLY TO THE INTRUSION SENSOR
1. Disconnect the intrusion sensor electrical connector, RF03.
2. ARM the security system.
3. Measure the voltage between RF03, pin 06, (YU) and GROUND.

- Is the voltage less than 5 volts?

-> Yes
REPAIR the circuit between the intrusion sensor and battery. This circuit includes the REM. TEST the system for normal operation.

-> No

G239843t93 : CHECK THE GROUND TO THE INTRUSION SENSOR
1. Measure the resistance between RF03, pin 01 (B) and GROUND.

- Is the resistance greater than 5 ohms?

-> Yes
REPAIR the high resistance circuit. TEST the system for normal operation.

-> No
CHECK for DTCs indicating a network or module fault. REFER to the DTC index.
