test modes are included within the mondeo's electrical system, these
are shown below:
is the module that controls the timing of devices such as the intermittent
windscreen wipers, the lights on chime and the 12sec interior light.
The module itself is plugged onto the bottom of the passenger side
footwell fusebox and is directly integrated with it. You can test
the unit it receiving a signal from the above switches/sensors by
pressing (and holding in) the heated rear screen switch whilst turning
the ignition on. The "chimes" will then start every time
a door is opened, the wipers put on, lights turned on, doors unlocked
with remote control or (where fitted) seat belts unfastened. You
can only exit this test mode by turning the ignition back off.
the engine running press and hold the left hand side function button
until the screen changes to show all the icons. Press it again to
scroll through the test functions:
- Pulses received from the VSS sensor. This will increment in 1's
the faster the vehicle is traveling.
- Pulses from the ECU. This will increment in 1's and the frequency
will alter with speed/throttle position
- Average consumption shown in Liters per 100Km
- Remaining amount of fuel in Liters or Gallons. O-C for not connected.
S-C for short circuit.
- Programmed error correction for fuel consumption. Default value
should be 0 but ranges between +/- 10 for Mk1 units and +/- 25 for
- Real time outside temperature display.
- Voltage recording on the "lights on" pin. Should change
with lights on or off.
- Software version of the trip computer.
module will test itself every time the ignition it turned on. The
entire panel should illuminate and then go off after 5 seconds with
the exception of the rear bulb fail lights - these require the brake
pedal to be depressed once before they are extinguished.
/ Central/Double Locking Module:
module can be tested by depressing the bonnet switch or opening
and closing a door 5 to 10 times in quick succession. (Under 10
seconds) Activation will be shown by either horn beeps, indicator
flashes or buzzer beeps (or a combination) depending on the system
and door, turning the key in a lock or ignition should make the
horn beep once. Opening the boot will make the horn beep twice -
once for the unlock command and once from the inhibit switch.
the test mode by leaving the car to stand for 20 seconds.
checking with indicator light - check
here for a code listing.
Automatic Temperature Control:
SATC Climate panel was first fitted to the mondeo in 98 and is Ford's
second generation of climate control. On board diagnostics (OBD)
is built into the panel to enable easy fault finding - the test
mode requires that the temperature inside the vehicle exceeds 10*c
(you'll get an erroneous error if not).
the vehicle and allow it to idle, change the temperature to "21*c"
(Note: If coming from "HI" then you must wait 30 seconds
before continuing). Set the blower control to "AUTO" and
the directional controller to "Windscreen". Now press
the A/C button and red "Temperature increase" button at
the same time, release and immediately press the blue "Temperature
decrease" button. At this point the SATC panel will enter OBD
and the display will change to a garbled but constantly changing
pattern to indicate that test results are being generated. The tests
will take between 20 seconds and 3 minutes during which time you
shouldn't press anything. When it completes the display with change
to show flashing error codes found, "88" indicates that
no fault was found with the system. If more then one error code
is found the display will flash them in series.

and return to normal operation or "Recirc" to keep the
fault found in memory and return to normal operation.
