Navigator 2WD V8-5.4L SOHC VIN L (1999)
SCDS Identification
The Speed Control Deactivation Switch (SCDS) involved in Recall 05S28 and the revised SCDS is illustrated below. See Figure 1.
Note that the revised SCDS has a different electrical connector. A jumper adapter (which is included in the parts kit) is required when replacing the old
SCDS with the revised SCDS.
SCDS Location
In most late model year vehicles involved in this recall, the SCDS is located on the master cylinder. In early model year vehicles (1992-1998), the SCDS
may be located on the master cylinder but is often found on a brake line distribution block or on the brake proportioning valve. If in doubt, just follow
the metal brake lines from the master cylinder until the switch is found.
^
On early model year E-Series vehicles, the SCDS is located on the left frame rail.
^
On E-450 models only, remove the 3 screws and position the coolant degas bottle forward to allow access to the SCDS and servo.
^
On F-53 vehicles, if the SCDS is not located on the master cylinder, it may be located in a brake line junction block approximately 457 mm (18 in)
below the master cylinder. It may be necessary to reposition wiring harnesses and/or remove add-on equipment in order to locate the switch.
^
On 1993 MARK VIII vehicles, the steering wheel intermediate shaft needs to be disconnected from the inside of the vehicle and the outside of the
vehicle, and then positioned upwards to gain access to the SCDS.
-
When the intermediate steering shaft is disconnected, the steering wheel must be in the LOCK position to prevent damage to the clockspring.
-
During installation of the intermediate steering shaft, new bolts must be installed. Tighten the bolts to 49 Nm (36 lb-ft).
^
On 1994-1998 MARK VIII vehicles, the SCDS is located underneath the right front fender splash shield in front of the right front wheel. It is not
necessary to remove the right front wheel to access the SCDS. Turn the wheel all the way right and position the front of the fender splash shield
aside.
^
On all Mark VIII vehicles (except 1993), the speed control servo is located underneath the left front fender splash shield in front of the left front
wheel.
