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 Mode
During cruising speed, the ECU receives inputs from the CTS, MAT, MAP, EGO, speed and knock sensors. It is also informed of throttle, gear (automatic transaxle models), and A/C control position.
The ECU provides a ground to the injector, precisely controlling injector time. It also controls idle speed, throttle stop angle, ignition timing, air/fuel mixture ratio and up-shift indicator lamp.
