A number conditions must be met for cruise control to be controlled by the engine control module (ECM). Some of these conditions are speed, the clutch and the brake pedal must not be depressed and certain diagnostic trouble codes (DTCs) must not be stored.

The clutch and brake pedal position sensors are checked to determine if they are in a position where the engine control module (ECM) allows cruise control.

NOTE:

On cars with automatic transmissions, the parameter for the brake pedal position sensor displays "Active" (the brake pedal position sensor allows the cruise control to function).

Ignition on
Using the VCT2000 (or appropriate scan tool), check if the clutch pedal position sensor and the brake pedal position sensor are in the " Active" position when the pedals are in the unaffected positions.

Check that the status changes when the pedals are depressed.

The brake pedal and the clutch pedal must be in the "Active" position for the engine control module (ECM) to allow cruise control.
