Engine will not shut off
Asked by Broke2 Aug 21, 2022 at 01:55 PM about the 2017 Cadillac ATS 2.0T Premium Luxury AWD
Question type: Maintenance & Repair
I have a 2017 Cadillac ATS that will not shut off when I push the Start/Stop
button. I changed the button and I still have the same problem. It continues to
run without the Que, the Switch, and with the battery cable removed. I have to
remove the ECM fuse to turn it off.

I think you should find a competent technician or garage and have it fixed A.S.A.P. Removing the batt cable's not a good idea .
better to pull the fuel pump fuse... computer relearning is not ideal.
Everything in this model runs through BCM/PCM. Good indicator is malfunctioning hvac security radio issues door locks that are opening and closing when alarm is set inop guages(intermitant) flashing security light. Failing run relay under hood fuse box
I don't pull the cable to stop it, as it will not work. These were methods that I used to test it so far to monitor the effects on the engine, I also pulled the start/stop switch and neither had an effect on the engine. Another guy mentioned that the Start/Stop Capicator my need to be reset or changed. I drained and reset the module with my scanner, and it was no help. I later replaced the start/stop capacitor control module which did not help either. I was curious if anyone had ever had to replace the actual start/stop capacitor before and what are the symptoms that it is bad?
