trolled by the Engine Control Module (ECM). A
cable and a vacuum controlled servo are not
used. This is a servo-less system. Control of the
system is accomplished by a 4-position, instrument
panel mounted switch (Fig. 1).

Switch settings (Fig. 2) are:
• 1. Set / Accelerate

• 2. Resume Set Speed

• 3. Set / Decelerate

• 4. Off
The system is designed to operate at speeds above

25 mph (40 km/h).

WARNING: THE USE OF SPEED CONTROL IS NOT
RECOMMENDED WHEN DRIVING CONDITIONS DO
NOT PERMIT MAINTAINING A CONSTANT SPEED,
SUCH AS IN HEAVY TRAFFIC OR ON ROADS THAT
ARE WINDING, ICY, SNOW COVERED, OR SLIP-
PERY.

OPERATION

When speed control operation is selected by the

speed control switch, the ECM (Engine Control Mod-
ule) allows a set speed to be stored in its RAM for
speed control. To store a set speed, press either of the
SET switch functions while the vehicle is moving,
and above 25 mph (40 km/h). In order for the speed
control to engage, the brakes cannot be applied, nor
can the gear selector be indicating the transmission
is in Park or Neutral.

The speed control can be disengaged manually by:
• Stepping on the brake pedal

• Pressing the speed control switch to OFF

• Depressing the clutch pedal (if equipped).

NOTE: Depressing the OFF switch or turning off the
ignition switch will erase the set speed stored in
the ECM.

For added safety, the speed control system is pro-

grammed to disengage for any of the following condi-
tions:

• An indication of Park or Neutral

• A rapid increase rpm (indicates that the clutch

has been disengaged)

• Excessive engine rpm (indicates that the trans-

mission may be in a low gear)

• The speed signal increases at a rate of 10 mph

per second (indicates that the coefficient of friction
between the road surface and tires is extremely low)

• The speed signal decreases at a rate of 10 mph

per second (indicates that the vehicle may have
decelerated at an extremely high rate)

Once the speed control has been disengaged,

depressing the RES/ACCEL switch (when speed is
greater than 30 mph) restores the vehicle to the tar-
get speed that was stored in the ECM.

While the speed control is engaged, the driver can

increase the vehicle speed by depressing the RES/AC-
CEL switch. The new target speed is stored in the
ECM when the RES/ACCEL is released. The PCM
also has a “tap-up” feature in which vehicle speed
increases at a rate of approximately 2 mph for each
momentary switch activation of the RES/ACCEL
switch.

A “tap down” feature is used to decelerate without

disengaging the speed control system. To decelerate
from an existing recorded target speed, momentarily
depress the COAST switch. For each switch activa-
tion, speed will be lowered approximately 1 mph.

REMOVAL

The speed control switch is mounted to the back of

the multi-function switch (Fig. 3). The multi-function
switch must be removed first to gain access to the
speed control switch mounting screw.

(1) Remove and isolate negative battery cable from

battery.

(2) Remove multi-function switch. Refer to Multi-

Function Switch Removal/Installation.

(3) Remove switch mounting screw (Fig. 4).
(4) Remove speed control switch from multi-func-

tion switch.

(5) Unplug pigtail electrical connector (Fig. 3) from

instrument panel wiring harness.

INSTALLATION

The speed control switch is mounted to the back of

the multi-function switch (Fig. 3).

(1) Position speed control switch to back of multi-

function switch.

(2) Install switch mounting screw (Fig. 4). Refer to

Torque Specifications.

Install multi-function switch. Refer to Multi-Func-

tion Switch Removal/Installation.

(3) Plug pigtail electrical connector (Fig. 3) into

instrument panel wiring harness. Be sure wires are
not pinched.

(4) Install negative battery cable to battery.
