Systems
From the late 1970s to the early 1980s Ford used a basic 2 digit system of EECIV,
sometimes called EECIV LED or EECIV basic. This system used the 3-pin oval
connector.
From the early 1980s Ford improved the systems and used the 3-pin triangular
connector. This is always coloured black with a red protective cover.
When Ford introduced newer systems from 1994, many vehicles had 3-pin and 16pin
connectors fitted, however, only one of them would be connected to the ECM,
depending on the Engine Management system used.
1994 - 1997 MY vehicles
Unfortunately there is no easy way of determining which system is fitted to these
vehicles, as it depends on the system Ford used: EECIV, DCL or EECV.
Firstly check under the bonnet and see if a 3-pin connector is fitted. If so connect
the scan tool using the relevant harness and select one of the EECIV systems from
the menu, (not EECIV basic). Generally the older CVH engines use 2 digit codes. The
Zetec engines generally use 3 digit codes. DCL and EECV systems never use the 3
pin connector.
DCL system uses either the 2-pin connector or the 16-pin connector.
NOTE: The DCL system is a variant of EECIV system.
The next step is to check for a 2-pin connector often fitted near the bonnet hinge. If
present, connect the 2-pin harness and select DCL from the menu.
NOTE: EECIV and EECV never use the 2-pin connector.
If neither of these connectors are present or connection cannot be made to the
vehicle using them, check in the passenger compartment for a J1962 16-pin
connector. This is usually located at the bottom of the 'A' frame pillar, in the
passenger footwell or under the steering wheel. If present, this connector will only
use either the DCL or EECV systems.
NOTE: EECIV and EECV never use this harness.
If this will not connect to the vehicle, use the Multiplexer cable (YTD965) or the
EOBD (J1962) cable (YTD950) and select EECV from the menu.
NOTE: Only EECV uses this harness.
