Location
1 The AWS control unit, and (when fitted) the bulb failure monitor, are located behind the glovebox on models up to 1987.

2 On models from 1987, the control and bulb failure modules are located behind the driver’s side footwell trim panel.

Testing
3 Thorough 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.

4 Investigation 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.

5 Note 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
6 Disconnect the battery negative lead.
