Checking Function of Control Unit

It is recommended to use a test lamp instead of the alarm horn (no noise).

1. Connect eight-pin plug on alarm control unit. Two-pin plug remains disconnected. Connect red wire of two-pin plug and term. 30 of control unit with help of a piece of wire. Connect test lamp between term. HN of control unit and red/yellow wire of two-pin plug.

2. Turn alarm system on (key horizontal) and open door. Lamp should flash. Make same test on both doors, trunk lid and engine hood.

3. Set off alarm by opening a door. Leave alarm system on and close door again. The alarm time should be approx. 30 seconds. Do not turn alarm system off.

The alarm should be set off again when opening, of example, a door.

4. Turn ignition on after alarm time has elapsed. Lamp should flash. Start engine. Engine must not start.

5. Disconnect test lamp and connect two-pin plug on control unit. Install control unit. Check function of alarm horn by setting off alarm again.

Replace alarm control unit in case of any type of malfunction.

Note

Even when the alarm system is switched off a defect in the control unit could cause failure of the ignition and/or fuel pump depending on circumstances.

The situation can be remedied by the following procedures should a new control unit not be available.

Remove alarm control unit and disconnect eight-pin plug.

Bridge both terminals 61 on plug with a piece of wire.

This prevents the alarm system from functioning.
