clutch797 Posted May 13, 2016 Share Posted May 13, 2016 So I have a 2013 fusion and it has the stupid auto start/stop feature. I hate it! If there was a longer delay in stop an go traffic it would be fine but every time I start my car I turn it off because I find it to be more of a PITA then helpful. Can I just unplug it from my console or would a dealer have to take it out of the ecu? 0 Quote Link to comment Share on other sites More sharing options...
clutch797 Posted May 14, 2016 Author Share Posted May 14, 2016 so no one knows? 0 Quote Link to comment Share on other sites More sharing options...
zip89105 Posted May 14, 2016 Share Posted May 14, 2016 Have you tried the owner's manual? My Fusion doesn't have start/stop so I can't give you an answer. If you don't have the owner's manual then go online to Ford and look for it there. 0 Quote Link to comment Share on other sites More sharing options...
WWWPerfA_ZN0W Posted May 14, 2016 Share Posted May 14, 2016 (edited) Using the OM, pg 151: Disabling Auto StartStop Press the Auto StartStop button located on the center console to switch the system off. The button will illuminate. The system will only be deactivated for the current ignition cycle. Press the button again to restore Auto StartStop function. Note: If the Shift to P, Restart Engine message appears and the amber Auto StartStop indicator light is flashing, automatic restart is not available. The vehicle must be restarted manually. See Information Displays (page 83). Edited May 14, 2016 by WWWPerfA_ZN0W 0 Quote Link to comment Share on other sites More sharing options...
timwil56 Posted May 14, 2016 Share Posted May 14, 2016 Looking at the 2013 owner's manual, fuse section, it doesn't appear that the Auto Stop Start feature has its own fuse and is most likely tied in with another electronic feature. Unless you can talk your service department into reprogramming the ECU (if that can even be done), I think you're out of luck. Try to make turning it off as routine as putting on your seat belt. 0 Quote Link to comment Share on other sites More sharing options...
drolds1 Posted May 15, 2016 Share Posted May 15, 2016 If it's not in the left-side menu, then it's not owner-configurable. Some BMWs can be programmed so that it defaults to off. I have no idea if Ford dealers have that capability. You could ask. 0 Quote Link to comment Share on other sites More sharing options...
clutch797 Posted May 15, 2016 Author Share Posted May 15, 2016 That's what im trying to figure out. Just as it can be added as an optional feature, can it be taken out? I hate having to turn it off every time I start my car. When it is on and the car stops at a light sometimes when it restarts it jerks violently. it seems ford didn't do enough research and development before adding it as an option to the car, it reminds me of how xbox and ps4 were in a race to be the first to get on the market. 0 Quote Link to comment Share on other sites More sharing options...
WWWPerfA_ZN0W Posted May 15, 2016 Share Posted May 15, 2016 (edited) Does it jerk violently at any other time when you manually do the stop/start? Does elapsed time between auto stop and auto start make a difference? How many miles on your Fusion? http://www.greencarreports.com/news/1077521_2013-ford-fusion-stop-start-ford-explains-why-its-different Ford’s new stop/start system utilizes a more powerful 12-volt starter battery, an upgraded starter motor and an extra transmission pump that maintains gearbox hydraulic pressure even with the engine off. It also uses new software to monitor and maintain battery voltage to ensure that the car can start cleanly and quickly when required, as well as a smart climate-control system that can start the engine early if the cabin gets too hot or too cold. Ford claims the system will help improve the 2013 Ford Fusion’s fuel efficiency by 3.5 percent, although as it fairly admits, the biggest influencing factor in gas mileage is the driver.

akirby Posted May 15, 2016 Share Posted May 15, 2016 It's not really new - hybrids have had it for years. Almost everyone says it's virtually unnoticeable so yours may be defective. If it can be permanently turned off it would be done by the dealer with their IDS. 0 Quote Link to comment Share on other sites More sharing options...
ElectricFan69 Posted May 16, 2016 Share Posted May 16, 2016 (edited) It's not really new - hybrids have had it for years. Almost everyone says it's virtually unnoticeable so yours may be defective. If it can be permanently turned off it would be done by the dealer with their IDS. Well, there are key differences - and the difference just may give the OP a solution. The MG spins the ICE a lot faster than the old-school starter motor, giving smoother light-off. The PSD also uses the other motor to provide moving power, eliminating the light-off lag. The ICE on the FFH doesn't directly power the accessories like A/C (i.e. via a belt). In a hot climate, having the A/C 'go out to lunch' at a stoplight would present an unacceptable (to most) pause in cool air. I would expect that any stop/start system would get an 'A/C override' that disables it while there is a demand for cool air. So, given the above, I'd expect that the stop/start will be suspended when the A/C is on except on very rare occasion. Turning on "Max A/C" should effectively turn it off.

Waldo Posted May 16, 2016 Share Posted May 16, 2016 Ford's start/stop is among the better ones, so maybe you do have an issue with an engine mount or something like that. I drove a $110,000 Range Rover the other day and the stop start on that was very jerky and annoying when restarting, much worse than any Ford I've driven. 0 Quote Link to comment Share on other sites More sharing options...
WWWPerfA_ZN0W Posted May 16, 2016 Share Posted May 16, 2016 There IS a procedure for removal of the Start/Stop activation/deactivation switch, so I suppose you could hardwire it to always off? Remove the console and shifter trim to get to the switch connectors. Nothing explicitly states whether the PCM defaults to ON and whether it would get befuddled by the hardwired-to-OFF switch. 2013 Fusion Auto StartStop System Wiring Diagrams.pdf 0 Quote Link to comment Share on other sites More sharing options...

Yes, HVAC concerns will cancel ESS but there are a lot of additional factors that can come in to play. To wit: The system automatically enables every time you start your vehicle if: - You do not press the Auto StartStop button (not illuminated). - Your vehicle exceeds an initial speed of 3 mph (4 km/h) after you have initially started your vehicle. - You have stopped your vehicle. - Your foot is on the brake pedal. - The transmission is in drive (D). - The driver door is closed. - There is adequate brake vacuum. - The interior compartment has cooled or warmed to an acceptable level. - The front windshield defroster is off. - You have not turned the steering wheel rapidly or you do not have it at a sharp angle. - The vehicle is not on a steep road grade. - The battery is within optimal operating conditions (battery state of charge and temperature in range). - The engine coolant is at operating temperature. - Elevation is below about 10000 feet (3048 meters). - Ambient temperature is moderate. - You have selected 4X2 or Auto mode. - The trailer is not connected. - You have not selected Tow haul. - You have not selected Manual or Sport mode. Automatic Engine Restart Any of the following conditions will result in an automatic restart of the engine: - You have removed your foot from the brake pedal. - You press the accelerator pedal. - You press the accelerator and the brake pedal at the same time. - The driver safety belt becomes unfastened or the driver door is ajar. - You have moved the transmission from drive (D) to any gear except park (P). - Your vehicle is moving. - The interior compartment does not meet customer comfort when air conditioning or heat is on. - Fogging of the windows could occur and the air conditioning is on. - The battery is not within optimal operating conditions. - You have exceeded the maximum engine off time. - When you press the Auto StartStop button with the engine automatically stopped. - The front defroster is turned to the Max setting. Any of the following conditions may result in an automatic restart of the engine: - You have increased the blower fan speed or changed the climate control temperature. - You have an electrical accessory turned on or plugged in. Note: You may notice that the climate seat fan fluctuates during an automatic restart. Note that some of these only apply to the F-150. In fact, some F-150 owners have found that covering the trailer harness plug is a workaround to disable the system. 1 Quote Link to comment Share on other sites More sharing options...

mattri Posted August 23, 2017 Share Posted August 23, 2017 On our 2017 selecting "sport" does not initiate after shut down and restart, necessitating another manual selection. Seems to not be much of a work around for just deselecting the auto on function on every start up. 0 Quote Link to comment Share on other sites More sharing options...

If so does that stay selected upon shut off & restart? Is your fusion a Sport trim? Details please? 0 Quote Link to comment Share on other sites More sharing options...

I don't know if Ford originally intended this to be permanent "off" but it's not. I does what pressing the switch does. and similarly re-sets ("ON") when you shut-down-restart. 0 Quote Link to comment Share on other sites More sharing options...

If the engine is well-tuned/maintained clean oil, it's so smooth you can barely tell it's on. So in that respect, it's almost un-noticable on the "stop". I'm not reminded I forgot to hit the switch until I lift my foot off the break, and the "start". That I notice. Positively not defective. probably comes down more to one's definition of "noticeable" 0 Quote Link to comment Share on other sites More sharing options...
