Ford Focus Battery & Cable Replacement! 2012 - 2018

[@waspywasps]

This is without a doubt the BEST and ONLY video I could find that covers every detail. I’m giving my first real attempt at doing something with my own hands on my own vehicle and this video gave me loads of information many others glazed over. Thank you so much for sharing.

[@BigBensCarsAndCycles]

@waspywasps I'm glad it helped! I'm having trouble finding the wiring video. I may have removed it because it only had 100 views after a year. Basically you get non-insulated butt connectors, non insulated crimpers, twist the wiring strands before entering the wire into the splice

Thank you for taking the time to make this video. My sister's local Ford dealership wants $600 to do that. 😞 I am 100% confident I can do everything for my sister except for I don't have a way to clear all the coats and stuff if they pop up.

[@batznbratz]

This is helpful my bfs 2018 had the wipers go crazy out of no where, and the negative terminal in the back had corroded everywhere

[@waspywasps]

Wait that exact thing happened to me. Wipers went crazy one day. Pulled the fuse for them since it almost never rains where I live. Lo and behold the negative terminal was corroded beyond belief. Now I’m having to replace the whole terminal since I neglected it for too long

[@terrykassem275]

Hello and thanks for your elaborate work and help on the Ford Focus! I have a 2014 Ford Focus SE, it cranks slowwwwly and never starts. It turns maybe for 4-5 turns then stops turning. I've replaced the 50A fuse, replaced the battery and starter. Nothing! It seems like it has spark, after testing one the spark plug, i haven't checked the fuel pressure yet but had attempted using starting fluid and I'm puzzled as to why it's cranking so slow even with a new starter and battery? Any help and guidance is appreciated! Thank you!

[@BigBensCarsAndCycles]

Hi, I'd be happy to help. Can you make a short video of trying to start it, and post it in my discord or Facebook group? Along with any fault codes you have

[@gorillafsoccer]

absolutely amazing video you are saving lives out here

[@waspywasps]

Could you link the video you mention titled “How to Repair Automotive Wiring”? 2013 Focus ST, I am replacing the negative terminal and need to replace the battery monitor as well

[@Jesse-ys8wu]

Looking at cables on RockAuto. Anyone know the recommend cable length for 18 Focus SE? Thanks. Car went two days ago and think this made my trans stop. Low acceleration and no reverse.

[@valstwitchy]

Excellent video! Now I just need the black cable. Anyone got a link on where to buy one? I’ve found a couple on amazon and eBay but seems like the cable/fuse are on wrong ends of the terminal.

[@OrangeRipperSaws-ll5vw]

I haven’t checked the alternator yet, but it was on the list, but the other thing I forgot to mention that I’ve noticed is that my other focus, same year and model makes clicking noises and the lights turn on then go off when I put the battery terminals on to the post initially, but notice this one doesn’t do that, just does nothing and makes no noises, any further insight what that may be or if it may correlate to my problem

[@CarGuyBayArea]

Do you have a video on replacing the battery monitor connecter.? Mine is corroded and broken

[@BigBensCarsAndCycles]

@@CarGuyBayArea hi, no. But you splice in the 2 wires and you'll be set

[@CarGuyBayArea]

@ thank you bro you’ve been a blessing have to go get parts and see if that fixes my no start problem .

[@frenchkey]

Great job. Even the box under battery is left dirty

[@rrabon84]

Hi thanks for the video, i have 2012 ford focus and has steering issues it says steering assist failure and low battery message pop up. Is there a possibility of steering assist failure due to low battery?

[@BigBensCarsAndCycles]

Yes, that can be caused by low voltage.

[@juniorchaviraaa]

i checked my battery terminals today and seen my bms has corrosion around the sensor it doesn’t seem like it’s coming from the battery terminals.. do you think they sell the whole piece with the new bms sensor & cable that connects to the ground strap without having to buy 2 parts and do the electrical work

[@BigBensCarsAndCycles]

@juniorchaviraaa the negative cable from ford comes with the sensor on it. But you'll need the connector separate only if it ends up needing it

[@ZakariyaBrunotte]

Solid tutorial thank you!

[@aravindanalin4857]

Hi ben, thanks for the all video's. I git issue with my 2012 focus. Car not starting after overnight parking. I replced the battery but still same . Got fault code p0702 so is it due to the battery cable or TCM. What should be the resistence of the good positive cable. Can you give me advuce for this..

[@BigBensCarsAndCycles]

Hi, thanks for watching! With the engine running, check voltage drop of the cable by putting the positive meter lead on the positive post, and negative on that 13mm nut holding the cable on the other side inside the battery box. Should be close to 0 volts being lost

[@aravindanalin4857]

Would a bad cable cause a po760 on a 2011 focus? Weve got the 4spd transmission. Crossing fingers its not being caused by the servo rod issue. Our 04 mazda grenaded its trans, and i buy this 2011 focus cause it didnt have the powershift trans and here it is throwing a solenoid code.

[@BigBensCarsAndCycles]

Hi, I think you should replace shift solenoid C

[@lynzbvb]

I did. It's still throwing a code for shift solenoid c, BUT it's an electrical fault for the shift solenoid c circuit. So going to try replacing the harness.

[@jorgergonzalezvisualartist8925]

Would a bad negative battery sensor cable give problems towards the fan motor not turning on? Also since I’m having to replace the whole negative cable with the sensor and the cable that goes into the firewall, I think not sure where it connects to? Could you use the information. Thank you.

[@BigBensCarsAndCycles]

The focus negative cable doesn't go into the firewall. I've got a Facebook group you can post this question at and add a picture if you can. Link is on my channel page

[@jorgergonzalezvisualartist8925]

@@BigBensCarsAndCycles Thank so much for the response, I’m just going to splice it like you showed on your other video. Seems is underneath the actual battery box and really don’t want to take the whole car apart. Thanks again!

[@ZakariyaBrunotte]

This seems to be the exact problem I’m having. Car has weird electrical issues and randomly won’t start. I think a short in the positive cable or a bad fuse

good morning In a 2015 focus, when you replace the battery, the car is not deprogrammed?

[@BigBensCarsAndCycles]

No, it does not get deprogrammed. Thanks for watching

[@OrangeRipperSaws-ll5vw]

Hey there buddy, On my 2013 focus se I got a no crank situation unless I put the transmission into the transmission learn by putting it in neutral. Battery light comes on after sitting at idle for a minute, and also not going into drive or reverse, just seems like neutral in all gears. The backup camera goes upside down occasionally, stays on in other gears other than R, and sometimes the lines aren’t showing. Do you know if this this 50a mega fuse you replaced can cause these sort of symptoms? The guy I got the car from couldn’t even get it to start but I managed that much. He changed the starter before I bought it because he thought that may be the problem. But I think it was the unknown underlying problem that made him think it was the starter causing a no crank no start situation all along

[@BigBensCarsAndCycles]

@@OrangeRipperSaws-ll5vw hmmm I would start with checking the alternator and battery

The white wire when replacing the + terminal wire, Where does it connect too? I was told it’s a fusable link but I can’t tell in your video. My car radio pops on real quick then says “system off to save battery” New battery, new alternator, fuses good, battery voltage all within correct limits 14.0v turned on 12.4 turned off. Any and all insight I appreciate hell I’ll pay you for help lol

[@BigBensCarsAndCycles]

That white wire is just a basic wire, no link in it that I'm aware of. You might want to check for corrosion damage do the battery monitor sensor on the negative terminal. Also try resetting the battery monitor sensor with forscan. OK hope that helps, that'll be $1,000 😃

don't you have to move all that crack (i.e. airbox, air intake) out of the way? i just had my battery replaced by AAA and i think the guy didn't torque the negative cable all the way down. i say this because sometimes my car won't start or micro-dies while driving and i've found pushing down on the negative cable fixes it for some reason. it's so odd.

[@KaKa-ol9ep]

Yeas, I did this without removing airfilter. It's hell hard. I beat my fingers and scratch battery. It's possible of course but not easy and not 5 minutes. Good luck)

[@becs2272]

You DO NOT need to remove all those parts! I'm a lady and just removed my battery out of 2014 Focus and replaced it. Just remove the metal bar that goes across the top of the battery. Definitely a pain to get it out but doable without removing all the extra parts.

You heard anything about grounding issues messing with the transmission? I keep hearing something about needing to sand off paint

[@BigBensCarsAndCycles]

On the early build focuses and Fiestas 2011-2012, some of them had paint in the threads of the ground bolts. That issue is long gone

[@schmick63]

My current project Focus has a bunch of seemingly unrelated codes. Worst is the P090C Clutch B Control Circuit low which prevents Reverse and 2/4/6 from engaging. Have swapped the actuators around and no change in codes. What's odd is that when the car is started from cold, all the gears including S can be engaged, however after 5 mins of idling the car will no longer go into S and Reverse does not work either. I also have code U0131:00 - Lost comms with Power Steering control module, even though the power steering works fine. This particular Focus is fitted with the 1.6 that's normally found in the Fiesta (entry level Focus in Australia) as and also has hydraulic power steer.

[@BigBensCarsAndCycles]

Gotcha. Sounds like a tcm problem.

[@schmick63]

Thanks for the reply. I have it booked at the dealer on Thursday so fingers crossed I can get a free TCM@@BigBensCarsAndCycles

[@BigBensCarsAndCycles]

@schmick63 you're welcome. I know my reply was pretty short lol but yeah sounds like an interesting car. We don't have a 1.6L focus in the US. And none with a hydraulic rack.

[@schmick63]

@@BigBensCarsAndCycles Found out today with this TCM code P090C that if you start the car when cold and put it straight into S mode, it drives fine with no issues. If you put it in D, you get about 3 mins of normal driving and then gears 2/4/6 and reverse no longer work. The 'S' gear also becomes unselectable on the dash cluster. Its at the dealer today hopefully for a new TCM, will be interesting to see what they 'find'

[@Cfchild1]

Great videos for the Focus owner! Question: Is it necessary to be required to reset the BMS through a scan tool only if you have replaced the battery?

Thanks, glad to help. You aren't required to reset bms when replacing the battery, but it's a good idea to especially if the old one was totally shot
