DESCRIPTION AND OPERATION

General Information

This section describes the operation and components

of the Powertrain Control Module (PCM). The system

is designed to provide optimal performance and

emission control. Modifying the system or substituting

non-Ford components may have an adverse effect on

drivability and emissions. Diagnosis of the system

requires special tools and training. Maintenance of the

PCM system should be performed by Ford trained

technicians.

Precautions

The fuel supply lines retain pressure that must be

relieved before servicing the fuel system. Leaking fuel

poses a potential fire hazard.
The spark ignition system produces high voltages.

Use care to avoid personal injury.
When the ignition is ON, the electric engine cooling

fans can start at any time. Keep clear of the fans to

avoid entanglement and personal injury.
With the engine running, there are rotating

components within the engine compartment. Use

extreme care to avoid entanglement and personal

injury.
Some components in the engine compartment are

HOT.
The cooling system contains hot liquid under

pressure. Allow the engine to cool to ambient

temperature before removing the cooling system cap.
Do not reconnect a PCM to the vehicles wiring

harness with the ignition turned ON.

Special Notes

With this issue of the Falcon Workshop Manual,

some terminologies in this section for PCM

components now reflect Ford’s Global Naming

Conventions. The full title of the component is

spelt out in full the first time it is mentioned in a

section. The acronym for the component is shown

in brackets and, where applicable, the previous

acronym is shown in Chevrons. Elsewhere in the

section, only the acronym is used.
Information in this section regarding the Traction

Control System is only applicable where fitted.
Information in this section regarding LPG applies

only to Ford Factory fitted LPG systems.

Installation of after-market LPG systems may

operate differently from that described here.
Information in this section regarding Air

Conditioning and Automatic Climate Control Air

Conditioning is only applicable where fitted.
