Test F

PINPOINT TEST F: THE SPEED CONTROL IS INOPERATIVE - NO DTCs

Test F1-F4:

Test F4-F7:

Test F8:

Normal Operation
Under normal operation the digital TR sensor enables the speed control switches to send signals to the PCM inputs for the speed control system. The PCM interprets the signals and then outputs them to the speed control actuator. The step-up motor in the speed control actuator then pulls the cable to the correct position enabling the speed control to be set. When the brake pedal is pressed the BPP switch and the speed control deactivator switch will intern deactivate the speed control system.
