Normal Operation
WARNING: This page is about a different car, the 2007 Lincoln Mark LT and 2007 Ford Pickup. However, it is still accessible from the selected car via links, so may be relevant.
Vehicles equipped with a manual transmission have an additional clutch pedal position (CPP) switch. The CPP switch, normally closed, supplies a ground signal to the powertrain control module (PCM) through circuit 306 (TN/LB). When the clutch pedal is pressed, the CPP switch moves to the open position, causing the PCM to lose the ground signal and deactivate the speed control.
Possible Causes
- Circuit 306 (TN/LB) short to ground
- CPP switch
- PCM
