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 module grounds the cruise engaged signal circuit when cruise control is engaged. The PCM monitors the cruise engaged signal circuit in order to determine when the cruise control is engaged. The PCM sends a class 2 message indicating that the cruise control is engaged to the instrument panel cluster (IPC ) (Buick Only). The IPC illuminates the cruise indicator. The cruise control module, cruise cancel signal circuit, is a circuit used by the PCM to inhibit cruise control when conditions inconsistent with cruise operation are present.
