    SRS ( Airbag system ) Diagnostic Fault codes

    Mondeo does not require bridging any pins to get code, if a fault is detected, SRS warning light will automatically flash fault code. Flashes Problem 1 Drivers airbag failure:- Driver airbag squib out of resistance 2 Passengers airbag failure:- Passenger airbag squib out of resistance 3 Failure of both airbag units:- failure of circuit commen to both airbags 4 Pyrotechnic seatbelt pretensioner failure (Either side) 5 Drivers airbag failure - System shorted 6 Passengers airbag failure - System shorted 7 Drivers crash sensor failure 8 Passengers crash sensor failure

    Common Fault:
    The airbag warning light flashing 4 times is a common fault on late Mk1 and all Mk2 mondeo's using the pyrotechnic pretensioners - especially if you have recently moved the position of one of the front seats. Turn the igntion off and allow the car to sit for 15 minutes. Underneath the front seat base, (access is best from the rear passenger footwells, with front seats furthest forward), you will find two cables wrapped in yellow sleeving. The yellow connector may have parted company with its other half - Even if it hasn't disconnect and reconnect it to ensure that it is secure. Move on to the passenger side and check the wiring there - whilst doing this ensure the cabling is slack and not badly routed resulting in it being pulled tight.

    Fuse Box Locations:
    Engine Bay Fusebox is located in the passenger side closest to the headlight and is accessed by releasing the spring clamp at the back.

    Passenger Footwell Fusebox is located behind and to the right of the glovebox. Open the glovebox and tug towards the rear of the car to aid access. There is a small black pin on the right of the fusebox that needs to be pulled in the direction of the floor in order to release the box from its mounting.

    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.

    Test 1:
    Make sure the ignition is switched off, the windows open and the vehicle is unlocked. Open the bonnet and operate the bonnet switch 8 times within 10 seconds.

    Infrared Programming Instructions:
    • Put your key into the ignition and turn to position 1 (Radio). After approximately 10 seconds the red alarm control LED (next to the clock) should illuminate. As soon as it comes on remove the key from the ignition - the LED should remain lit.
    • Point the remote's "eye" at one of the front door sensors and press the rear button until the light on the transmitter illuminates (Keep the button pressed)
    • With the rear button held in press the front button 4 times then release both at the same time. The control lights in both clock and fob will flash 4 times to indicate programming complete.
    • Turn the ignition back on to exit programming mode
    Radio Frequency Programming Instructions:
    • Insert the ignition key and turn from position II (Ignition) to position 0 (All off) and back four times within three seconds.
    • Remove the ignition key. The locking control system is now in "learn mode" for the next 20 seconds and the red warning system LED (By the clock) stays on continuously to indicate this.
    • During the 20 seconds press one of the transmitter buttons. The remotes signal and code number is learned by the locking module and is indicated by flashing the warning system LED.
    • Wait until learn mode times out (20 seconds) or switch the ignition back to ON.
