Location
1The AWS control unit, and (when fitted) the
bulb failure monitor, are located behind the
glovebox on models up to 1987.
2On models from 1987, the control and bulb
failure modules are located behind the driver’s
side footwell trim panel.
Testing
3Thorough testing and fault finding should
be left to a Ford dealer or other electrical
specialist, having test equipment. Unskilled or
uninformed testing may cause damage.
4Investigation of malfunctions should begin
by checking that all wiring is intact and
securely connected. If checking wires or
sensors for continuity, always disconnect the
control unit and/or bulb failure monitor before
so doing, otherwise damage may be caused.
5Note that false oil level readings can result if
the car is parked on a slope. False bulb failure
warnings may occur if incorrect wattage bulbs
are fitted.
Removal and refitting
