What kind of stop and start system does GM use?
There are three types of 12V Stop/Start systems that have been used in GM vehicles: 1 The Two-Battery system that includes an auxiliary 12-volt battery. 2 The DC to DC system that features a power supply transformer. 3 The Ultra Capacitor system that has capacitors that provide a voltage boost during engine restarts.
How long does it take for a GM engine to start?
Once the brake pedal is released or the accelerator pedal is depressed, the engine will restart. It takes about 0.3 seconds for the engine to start from the time the brake pedal transition initiates the restart. There are three types of 12V Stop/Start systems that have been used in GM vehicles:
How does the Auto Stop / Start system work?
The Stop/Start system will automatically turn off the engine, referred to as an Auto Stop (Fig. 1), when the brake pedal is applied and the vehicle is at a complete stop, if various operating conditions are met. Once the brake pedal is released or the accelerator pedal is depressed, the engine will restart.
Where is the Stop / Start switch on a GM car?
During an engine restart, the module opens the switch to ground and closes the switch to the capacitors to provide a boost in voltage to the vehicle’s electrical system. The Ultra Capacitor system features a Stop/Start disable switch located on the instrument panel or center console.
