Operation CHARM: Car repair manuals for everyone.

Actuation of Alarm






When the alarm is armed, it is set off if alarm data is received by the control module on the following connections:
- The door switch is grounded (pin 4).
- The bonnet switch is grounded (pin 16)
- The luggage compartment switch is grounded (pin 3).
- Signal from the glass breakage sensor (pin 7)
- Signal from the sensor's disconnecting button (pin 7)
- Connecting or bypassing the ignition switch, "ON" position (+15) on the ignition switch (pin 10).

When the alarm is set off, the horn sounds for 30 seconds and the direction Indicators flash for 5 minutes.

Anti-theft alarm
The starter motor and fuel pump relays, and the engine management system's +15 circuit are blocked for 30 minutes. Each fresh attempt to start extends the blocking time by 30 minutes. If the ignition is switched on, blocking will continue as long as the alarm Is armed.

Anti-theft alarm with VSS
The engine management system prevents the engine from being started.

To turn off an actuated alarm, disarm it in the usual manner by means of the remote control unit or the car key (Anti-theft alarm).


Important: This type of alarm tripping is standard (at delivery). Flash and sound times can be reprogrammed as required by the local market.
