A5.9.8 Intrusion sensors
1. Check harness wiring continuity as shown below:
SLCM connector Sensor connector Function
Lsft-hand side sensor
pin 10 pin 2 ground
pin
11 pin 4 40kHz
pin 12 pin 5 I/P
pin 13 pin 3 +av
RightAand side sensor
pin 2 pin 2 ground
pin
3 pin 4 40kHz
pin 4 pin 1 I/P
pin 5 pin 3 +av
2. Lock and arm the vehicle while sat inside; wait 15 seconds, then attempt to cover either sensor rea
with the palm
of the hand. Check that sensor detects movement and activates alarm. Repeat test
for second sensor.
