ALARM OPERATIONAL DESCRIPTION

Operational Description

The alarm system is fully managed by alarm control unit M030. The control unit receives an ignition-operated supply protected by fuse F27 - located in underfacia control unit B002 - and a direct battery supply protected by fuses F60 and F34 - located in optional junction unit B101 -.

The control unit comprises two connectors, A and B, with the following pin-outs:

Connector A:

• pin 1: deterrent Led activation/deactivation;
• pin 3: battery supply;
• pin 4: system deactivation from remote key I100 - pin 1 connector B -;
• pin 7: system activation from remote key I100 - pin 2 connector B -;
• pin 8: volumetric sensor power supply K062 - pin 1 -;
• pin 9: earth connection C010 - pin 10 -;
• pin 11: earth reference for volumetric sensors K062 - pin 3 -;
• pin 12: volumetric sensor power supply K062 - pin 2 -.

Connector B:

• pin 1: right turn signal power supply to control panel H090 - pin 7 connector A -;
• pin 2: left turn signal power supply to control panel H090 - pin 5 connector A -;
• pin 7: power supply direct from battery for controlling right and left turn signals;
• pin 8: left front door open signal input from control panel H090 - pin 1 connector A -;
• pin 9: right front door open signal input from control panel H090 - pin 1 connector A -;
• pin 12: ignition-operated power supply;
• pin 13: shared power supply for remote key I100 - pin 2 connector A -;
• pin 16: right sliding door and door flaps open signal from control panel H090 - pin 6 connector A -;
• pin 18: bonnet open signal input, from switch on bonnet I010 - pin 1 -;

Remote control receiver M035 controls vehicle door catch closure/opening. More specifically, door unlocking is controlled from pin 5. The signal is distributed to the catches by short-circuiting junction D0971. Door locking is controlled from pin 6, distributed from short-circuiting junction D097G. Pin 3 receives a power supply directly from the battery while pin 7 receives an ignition-operated power supply.
