The cruise control system maintains the desired vehicle speed under normal driving conditions. The cruise control system has the following capabilities:

Depressing the SET and the R/A switches simultaneously will cancel the cruise control operation. Canceling the cruise control operation will not cancel the speed memory.

The cruise control system contains the following components:

The cruise control switch is on the turn signal lever and controls the cruise control system. With the ignition switch in the RUN position, voltage is supplied to the cruise control switch from the I-3 fuse through CKT 241 (BRN). When the cruise control switch is in the ON position, power is supplied to the PCM (connector 2, cavity A11) through CKT 397 (GRY).

With the SET button activated, voltage is applied to the PCM (connector 2, cavity 4) through CKT 84 (DK BLU). The PCM will monitor the vehicle speed sensor (VSS) and maintain the speed the vehicle has reached when the SET button is activated.

With the R/A (Resume/Accelerate) button activated, voltage is applied to the PCM (connector 1, cavity 5) through CKT 87 (GRY/BLK). This button will only resume speed after an initial speed has been set using the SET button. With the cruise control system on, this button will also accelerate the speed of the vehicle. When the switch is released, the system will maintain the new speed.

Both the Torque Converter Clutch (TCC)/stoplamps switch and the stoplamps switch will disengage the cruise control system. This is done when the brake pedal is depressed.

The contacts in the TCC/stoplamps switch open and the signal to the cruise control module is interrupted. The contacts in the stoplamps switch close and a voltage signal goes to ground in the cruise control module. Both the absence and presence of these voltage signals cause the cruise control module to disengage the cruise control system.

The cruise control system contains the following components:

The cruise control module receives power from the I-3 fuse through CKT 241 (BRN) and is grounded at G 108 through CKT 451 (BLK/WHT).

The cruise control module monitors the vehicle speed from the vehicle control module (VCM) and operates the stepper motor. In response to the cruise control module, the stepper motor moves the cruise control cable. The cable moves the throttle linkage in order to vary the throttle position and maintain the desired speed.

The cruise control module contains a low speed limit which will prevent the system from engaging below a minimum speed of about 25 mph.

The cruise control switch is on the turn signal lever and controls the cruise control system. With the ignition switch in the RUN position, voltage is supplied to the cruise control switch from the I-3 fuse through CKT 241 (BRN). When the cruise control switch is in the ON position, power is supplied to the cruise control module, cavity A, through CKT 397 (GRY).

With the SET button activated, voltage is applied to the cruise control module, cavity B, through CKT 84 (DK BLU). The cruise control module will maintain the speed the vehicle has reached only when the SET button is released.

With the R/A (Resume/Accelerate) button activated, voltage is applied to the cruise control module, cavity C, through CKT 87 (GRY/BLK). This button will only resume speed after an initial speed has been set using the SET button. With the cruise control system on, this button will also accelerate the speed of the vehicle. When the switch is released, the system will maintain the new speed.

Both the Torque Converter Clutch (TCC)/stoplamps switch and the stoplamps switch will disengage the cruise control system. This is done when the brake pedal is depressed.

The contacts in the TCC/stoplamps switch open and the signal to the cruise control module is interrupted. The contacts in the stoplamps switch close and a voltage signal goes to ground in the cruise control module. Both the absence and presence of these voltage signals cause the cruise control module to disengage the cruise control system.
