LED





As a test function for the theft alarm, there is an LED mounted in the facia. This is controlled by the control module (pin 2) and flashes (with varying frequency) or lights continuously depending on the different conditions. Some normal cases are shown on the table.

Self diagnostics
Each time the alarm is armed, a self diagnostic test is conducted during the delay period (10 sec) while the LED is lit. If a fault is revealed, a diagnostic trouble code is stored in the control module and the LED flashes once every second. Other alarm functions are not affected.
