LED (Light Emitting Diode)





General

As a check for the theft alarm, an LED is mounted in the centre of the dashboard. The LED flashes at varying frequency or lights continuously depending on the different conditions. The table overleaf shows some normal cases.

Function

The LED is supplied via +30 from fuse 9 (22a) and grounded via pin 27 on the TWICE control module. TWICE controls the ground and hence activation of the LED and its flash frequency.

Self diagnosis

Whenever the alarm is armed, a self-diagnosis is carried out during the delay time (10 seconds) while the LED is lit continuously. If a fault is found, a diagnostic trouble code is stored in the control module and the LED does not flash. The other functions of the alarm are not affected.
