Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Cruise Control Engaged
The cruise control system will engage and adjust vehicle speed based on the activation of the following cruise control switches:
- On/Off
- R/A
- Set/coast
The cruise control switches are located on the multifunction/turn signal lever.
The cruise control module monitors the signal circuits of the cruise control switches in order to determine when to capture and maintain the selected vehicle speed. The cruise control module receives the vehicle speed signal from the PCM, via the vehicle speed signal circuit. The cruise control module is an electronic controller and an electric stepper motor. The electric stepper motor moves a strap that is attached to the cruise control cable in order to move the throttle linkage.
Ignition positive voltage is supplied from the 10 ampere CRUISE fuse, to the cruise control switch and to the cruise control module via the ignition 3 voltage circuit. When the cruise control On/Off switch is in the On position, the cruise control module detects a high signal voltage on the cruise on switch signal circuit. When the Set/coast button is pressed, the cruise control module detects a high signal voltage on the set/coast signal circuit. In order to engage the cruise control system, the On/Off switch must be On and the Set button momentarily pressed. The cruise control module will record the selected vehicle speed. When the R/A switch is pressed, the cruise control module detects a high signal voltage on the resume/accel switch signal circuit. Momentarily pressing the R/A switch will recall the previous selected vehicle speed that is recorded in the cruise control module, when the cruise control system has been disengaged by depressing the brake pedal or the clutch pedal. Pressing and holding the R/A switch when the cruise control system is active will allow the vehicle to accelerate to a vehicle speed greater than the current set vehicle speed. When the R/A switch is released, the vehicle speed will decrease to the current set vehicle speed. Pressing and holding the Set/coast switch when the cruise control is active will allow the vehicle speed to decrease from the current set without deactivating the cruise control system. When the Set/coast switch is released, the vehicle will accelerate to the current set vehicle speed.

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.
