GM Start/Stop Control Module

The SS-GM-01 is a start/stop control module for 2019 and newer C4500-6500 General Motors trucks that are manufactured with Power Takeoff (PTO) and remote PTO controls enabled. With proper application, it provides a fully integrated and reliable system for start/stop control of the chassis engine. When first powered up, the SS-GM-01 will be in Engine Off Mode. When a momentary ground is applied to Input 1, the start/stop module will activate the remote start sequence. Once the engine is running, if a momentary ground is again applied to Input 1, the start/stop module will activate the remote stop sequence. The SS-GM-01 may also be programmed to provide other functions, such as dual voltage monitoring of chassis and auxiliary batteries, and frequency/time measurement.
