Cruise Control Module: Description and Operation
2001 Chevrolet Lumina V6-3.1L VIN JSECTION Description and Operation
The cruise control system uses a cruise control module to obtain and hold any desired vehicle cruise speed above a minimum speed of 40 km/h (25 mph). The module contains the following 2 components:
^ An electronic controller
The electronic controller monitors the following operations:
- The vehicle speed
- The multi-function turn signal lever
- The cruise control release inputs
- The brake switch inputs
- Operates the electric stepper motor
^ A stepper motor
The stepper motor moves the internal band in response to the controller in order to maintain the desired cruise speed. The internal band is linked to the throttle lever via the cruise control cable.
The Cruise Control Module sends the cruise status input to the PCM to indicate when cruise control is engaged.
The PCM monitors the cruise status signal while commanding cruise to be disengaged via the cruise inhibit circuit. Any of the following conditions may cause the PCM to inhibit cruise control operation:
The cruise control module terminal k is the vehicle speed signal input terminal through circuit 817. In operation, the voltage varies between 0.0-5.0V. The cruise control module terminal J is used to signal the Powertrain Control Module (PCM) when cruise control is engaged through circuit 85. The PCM will then determine the correct shift pattern for the transmission. The cruise control module terminal H is used by the PCM through circuit 83, to inhibit cruise control when conditions inconsistent with cruise operation are present.
The PCM will inhibit cruise control under the following conditions:
^ When vehicle speed is less than 40 km/h (25 mph).
^ When PARK, REVERSE, NEUTRAL, or 1st gear is indicated by the transaxle range switch.
^ When an over/under battery voltage condition exists.
^ With low engine RPM.
^ With high engine RPM (fuel cut-off).
^ ABS system is active for longer than 2 seconds.
^ An electronic controller

When to See a Mechanic
Stop DIY work and contact a certified mechanic immediately if any of the following apply:
- • You smell fuel, burning insulation, or see smoke.
- • Brakes feel soft, pull hard to one side, or make grinding noises.
- • The engine overheats, stalls repeatedly, or misfires under load.
- • You are missing required tools, torque specs, or safe lifting equipment.
- • You are not confident in the next step or safety outcome.
