Cruise Control Switch: Notes

WARNING: This page is about a different car, the 2010 Chevrolet Aveo. However, it is still accessible from the selected car via links, so may be relevant.

The cruise control switch is an input to the instrument panel cluster (IPC). The IPC monitors the cruise control set/coast and resume/accelerate switch signal circuit in order to detect when a cruise control function has been requested. The IPC detects a specific voltage signal on the cruise control set/coast and resume/accelerate switch signal circuit when a cruise control function switch is activated, with each switch having a different predetermined voltage value. Once a cruise control function has been requested, the IPC sends a command via serial data to the engine control module (ECM). After the main switch is turned ON and the neutral position of the switch is detected by the cruise control actuator, the following operations can be performed by using the cruise control switch:
