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.
Circuit Operation
Battery voltage is applied to terminal 2 of the cruise control module when the ignition switch is in the ON position. When the cruise control switch is pressed to the CRUISE ON OFF position, ground is applied to the internal switch of the cruise control module at terminal 11.
The cruise control switch signals the cruise control module (CCM) at terminal 11 to enter the CANCEL, SET/COAST, or RES/ACC by using varying amounts of resistance depending on the mode selected.
Ground is supplied to the CCM at terminal 16 from G200.
Outputs from the CCM are found on the following terminals:
- 5 - cruise control indicator - completes the circuit to light the cruise control indicator
- 7 - servo motor
- 8 - magnetic clutch - for the servo motor
- 10 - DLC
- 14 - O/D cut control - informs the PCM to downshift from overdrive
- 15 - servo motor
Inputs to the CCM are found on the following terminals:
- 2 - Ignition Positive Voltage
- 4 - cruise interrupt signal - transaxle range switch not in DRIVE (D) or clutch pedal pressed
- 6 - shift solenoid 2 control - informs the CCM when the transaxle is in 2nd or 3rd gear and is out of overdrive mode
- 8 - brake signal - disables cruise when the brake pedal is pressed
- 11 - cruise control switch - mode switch
- 12 - vehicle speed - from the PCM
- 13 - idle signal control - informs the CCM when the accelerator is pressed and engine is above idle
- 16 - ground
Cruise control will be disabled when one or more of the following conditions exist:
- The VSS is less than 40 km/h (25 mph).
- The transaxle range switch indicates that the vehicles is not in DRIVE (D).
- The clutch pedal is depressed - manual transaxle.
- There is an over/under battery voltage condition.
- The brake pedal is pressed
- The engine RPMs are low - idle.

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.
