Cruise Control
P0564 Cruise control multi-function input signal
P0578 Cruise control multi-function input “A” circuit stuck
P0571 Brake switch “A” circuit
Description
Cruise control requests are made using a multi-function switch input. Each cruise control function switch selects
a different resistive network to a single ECM input. From this input the ECM determines the driver request.
In addition cruise control is cancelled by the application of either the brake pedal or the clutch pedal (see also
P0806, P0807 and P0808).
