Ford testing instructions - Alarm System

Anti-Theft Alarm/Double Locking System Service Test Mode:

Note:
Vehicles fitted with central/double locking and remote control but without anti-theft alarm will not emit any horn beeps. The test results will be indicated by hazard operation only. The anti-theft alarm/double locking Service Test Mode is designed to enable service personnel to trace faults easily. The service mode can be entered at any time providing the central locking system has not been activated. Operating any ajar switch or the bonnet switch 8 times within 10 seconds will activate the service mode.

Indications During the Service Test Mode:

1. Upon entering the Service Test Mode the alarm indicator LED will illuminate continuously and a number of horn beeps indicate the status of the system:
2. The first horn beep indicates activation of the service mode.
3. The second horn beep indicates that no fault has been recognised during any previous alarm system activations.
4. The third horn beep applies to interior scanning only and indicates that no fault has been recognised with the system during any previous interior scanning activations.

Each activation of a set/reset switch (located on the lock barrel of each front door) is indicated by one short horn beep. A correct central locking signal (status of the lock/unlock lines) is also indicated by one short horn beep. The second horn beep must occur within three seconds of the set/reset switch activation.— During the service mode an activation of any alarm sensor/switch will be indicated by a single short horn beep and/or a short hazard signal.— If there is no activation of any alarm sensor/switch for a period of 20 seconds, the system will exit the service mode (indicated by one short horn beep) and the alarm indicator LED will extinguish.

Service Test Mode Sequence:

Note:
Make sure the central locking is working correctly and note that the test steps must be carried out within 20 seconds of each other to prevent the system automatically leaving the Service Test Mode. Should this occur, start the procedure again as described in Test 1 and continue with the diagnosis. If a vehicle is not fitted with an anti-theft alarm system, start the Service Test Mode at step two.
