I read where if the trunk battery gets too low, it will disable the auto stop. Well, I unhooked the battery and it doesn't. I also tried placing the shifter in "L" pushing the plus until it goes through the gears and that doesn't work either. Isn't there a relay or sensor that can be pulled/disabled to stop the auto stop feature?

 

maybe try unplugging the battery current sensor connector.

 

OK, where would that be?

 

on the older models they used to be a amp clamp on the negative battery cable
try google for battery current sensor

 

Thanks for the input.

 

I googled it, probably not a good idea to remove it.

I did some more digging and it seems by pulling the hood latch sensor disables the auto-stop. If it thinks the hood is open, it doesn't work. I found this out by running across a tip for temporarily disabling the auto-stop. You start the car, pop the hood and then close it. This action will disable the auto-stop until the next time the car is started. Pulling that sensor does the same thing but for good.

 

it won't kill the battery or surge the motor. the pcm controls the battery charging...the sensor is just an input to the pcm. As far as turning on a dtc….it may for chevy but doesn't for dodge products. for dodge it sets a code but the code does not turn on the check engine light.

dodge vehicles have a push button shut off but people are to lazy to push the button every time they start the engine...so they remove the battery sensor connector.

manufacturers can't legally make a permanent shut off due to epa regulations regarding fuel consumption ratings.

imo, I would leave it connected as long as the ss system is working correctly as the battery sensor provides other charging system advantages that increase fuel mpg and increase battery life.

Overall the ss system is good. I do not like it when im in stop and go traffic. the temporary shut off is wonderful.

 

they are probably ten inputs that the ss needs to see to operate
-seatbelt, coolant temp, battery state of health, gear position
if you are ok with having a hood ajar light..go for it.

 

I'll put up with the hood latch light any day to get rid of the auto-stop mode.
