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.
Confirmation Test
After repairs have been completed, confirm that problem has been eliminated. Operate system under same conditions recorded for original complaint and perform Cruise Control Input Signal Check. See CRUISE CONTROL INPUT SIGNAL CHECK . If problem is no longer present, no DTCs are present, and all cruise control input signals are okay, repair has corrected problem. If problem is present, DTCs are present, or not all cruise control input signals are okay, further diagnosis and repair is required.
