LED






As a control for the theft alarm, there is an LED mounted in the loudspeaker grille on the left-hand side of the facia (or on the right-hand side in RHD cars). This is controlled via the control module (pin 2) and flashes (with varying frequency) or lights continuously depending on the different conditions. A number of normal cases are shown in the table on the next page.



Important : Delay period (10 sec) does not start until the delayed interior lighting goes out (approx. 18 sec).



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.
