DESCRIPTION AND OPERATION Interior Lamp Functionality
The anti-theft alarm ECU controls the interior lamp functionality. When the lamps are extinguished, they fade out
to the off condition over a 2 second period.
The lamps are turned on by:
Disarming the alarm using the remote handset
Opening any door.
When the lamps are on, they will be extinguished by the following actions:
If all doors are closed, the lamps will be extinguished after a 15 second delay period
If any door is left open, the lamps will be extinguished after an 8 minute delay period
If one of the above delay periods is active and the ignition is switched on or the alarm is armed, the lamps will
be extinguished.
ANTI-THEFT ALARM SYSTEM SELF TEST
The anti-theft alarm ECU has a self test feature which allows all alarm inputs to be tested. To enter self test mode
the following steps must be completed as follows:
1.Ensure that the driver’s door is closed and the driver’s window is open
2.Open the bonnet and with assistance depress and hold the bonnet switch
3.Release the bonnet switch and within 0.5 seconds turn the ignition switch on to position II
4.Quickly open the driver’s door
5.Turn the ignition switch to the off position
6.Turn the ignition switch back to position II
7.If the self test mode has been entered successfully, confirmation will be given by the alarm sounder. If the
ECU has not entered self test mode, repeat the above procedure.
Once in self test mode, the following test inputs will cause the security LED to illuminate and the engine
immobilised warning lamp and the hazard warning lamps to flash. When an input is operated, non illumination of
the security LED, the engine immobilised warning lamp and the hazard warning lamps indicates a fault for that
input.
Perform the following steps to test each input for correct operation:
Close and open the drivers door
Open and close each of the passenger doors and the tail door in turn
Close and open the bonnet (depress switch if bonnet still open)
With drivers door closed, lock and unlock the driver’s door using the vehicle key if spare key available. If spare
key is not available, operate driver’s sill button through open window
Press the unlock button of the remote handset. This enters the volumetric self test mode and all other inputs
will be disabled. Make a movement inside the vehicle. When the volumetric sensor is triggered the security
LED will flash.
To exit the self test mode, turn the ignition switch to the off position.
