some cars maby but no these ones hence the service manual entryArent you able to reset the bms just by letting the car sit overnight or unused for a specific period of time(x amount of hours) without the use of a scanner or forscan?
Pretty sure i read that in a thread before with that being procedure mentioned.
I got some weird things going on with my battery.. sometimes when go to my car, before I unlock I see on the screen, a little status bar and it says "shutting off car to save battery" but it's been on all night and then when I start the car, it's like the battery is drained, pushbutton start takes like 3 or 4 seconds of cranking..if I press pushbutton once to power acessories with car off, it turns off after not even 4 minutes.. used to stay on for 10 to 15.. battery is still testing good, it's 590CCA, testing around 520CCA but close to replace... anyone have any good recommendations for batteries, I would like a AGM type with more CCA then oem. Optima redtop used to be a go to, they are not as good anymore and too expensive
My Focus is coming due for a battery can I just replace the battery and call it good. I spoke with 2 different dealerships in my area and they told me That the BMS will reset itself and they never heard of it needing to be reset.
keep in mind they may or may not reset the bms and if they dont they may fight you about it.After some shopping around I found that I'll just take the car to the dealership for a battery replacement. A battery from O'Reilly is 129 and a battery from Autozone is 159. The dealership told me it's 150 plus tax to replace the battery so that's the route I'm going to take. Thanks everyone for the info.
yeah tell that to mine that will go for yrs with out auto resetting. its in the bloody shop manual what more proof do you need. they dont auto reset and fyi cars will run fine like they always have with them not reset. only thing it effects is the accessory like the 1hr mode and such.You DO realize of course that no car will run forever without 'resetting the battery' on its' own right? The alt does it on its' own or it is not working correctly. Impossible not to.
Ford just created one more gimmick to scare people to go to the dealers there.
Let the car sit with new battery in it at least 8 solid hours and may need more, then problem is gone. Without Ford's quick reset method the battery does it by itself but a time based thing.
By "Activate the headlight flasher", do you mean flash the highbeams or do you mean press the hazard lights button?Procedure
Note: Only reset the sensor if the battery was replaced.
Vehicles without rear fog light key:
Perform steps 1-3 within 10 seconds
1. Ignition ON, Engine OFF
2. Activate the headlight flasher 5 times.
3. Fully depress the brake pedal 3 times.
4. If the battery charge indicator lamp in the instrument cluster flashes 3 times in 15 seconds, then the reset was successful.
Can someone confirm that this method posted by Bud Bundy is working?For a reset of the BMS:
1. Switch on ignition (do not start engine)
2. Switch on dipped beam
3. Press 5x the rear fog light button (do not switch 5x on and off the rear fog light)
4. Press 3x hazard lights button (do not switch 3x on and off hazard lights)
5. Then the battery symbol in the speedometer should flash 3x quickly.
If it does not flash immediately, wait 20 seconds.
Sorry to be stoopid but what is a headlight flasher?This might be the BMS reset procedure for cars without rear fogs. Found in an Amazon review of all places. If the link below dies someday, the “manual reset” instructions were loaded in an aftermarket reset scanner that gave instructions for cars with and without a rear fog light button.
The procedure for cars WITH rear fogs is the same as Bud Bundy posted earlier, except Bud had an added a step after #1 saying the dipped beams need to be on. So maybe that needs to be in there?
