I was able to replace my 12 volt battery using an Advance Auto 67R battery. They had an online code for 25% off that saved me $40. Nice. I also was able to reset the Battery Monitoring System using a Veepeak OBD2 scanner and the free Forscan app running on my laptop. It seems like the laptop version has more features than the Android version. I did not need to upgrade to the advanced version of Forscan. Thanks again to all of your help! Would you mind sharing the model # on the Veepeak OBD2 Scanner? When I checked it out on Amazon there are quite a few options! Also, a link to the Forscan App for PC would be super!

Thanks in advance! https://forscan.org/home.html This site has info on adapters and links to the APP. The required OBDII adapter and App depend on what OS you are using on your device. Most times cheaper adapters will work but if you are going to record data, you’ll want to use the FORScan recommended ones as the cheaper ones may stop in the middle of a recording resulting in loss of recorded data. In addition, if you want to scan modules on both the HS and MS CAN, make sure the OBDII adapters can do this either automatically or with a toggle switch.

seattleCMAX Posted February 15, 2021 Report Share Posted February 15, 2021 On 4/5/2020 at 1:10 PM, plus 3 golfer said: OK, I reset my 12 V battery age from 753 days to zero days by doing the following: 1) Placed car in ACC mode by pushing start button without foot on brake. Again, it may also work in ready to drive mode. In ACC mode, the DCDC converter does not charge the 12 V battery (set point voltage is 10.6 V). The DCDC converter sets the voltage at 13.0 V which basically is a float charge to keep the 12 V battery from discharging. 2) Operated high beam switch 5 times. 3) Pumped brake pedal 3 times. 4) 12 V battery age changed to 0 days. I did not notice anything else happening on the dash to indicate acceptance of the change of battery age. Maybe I missed it I then put car in ready to drive mode and am currently recording FORScan data. I will analyze data and compare to data I recorded around 6 months ago after about 50 minutes of recording. The first point noted was the Set Point Voltage appeared to be higher than previous even though my current SOC is several % higher than previous. I may start a new thread comparing results and adding to those results as the 12 V battery ages. Like I said in other threads this is the second time I zeroed out battery age. My current battery will be 5 years old in June 2020. Did you get any sort of confirmation after doing these steps? I've read elsewhere that the battery light in the dash is supposed to flash three times if the BMS reset worked, but nothing happened for me when I followed your instructions. Thanks for the help!

I've read elsewhere that the battery light in the dash is supposed to flash three times if the BMS reset worked, but nothing happened for me when I followed your instructions. Thanks for the help! I just used Engineering Test Mode to light up all lights on dash. There is no "battery light display" on the dash. I confirmed using the FORScan APP that the procedure did reset the battery age and PIDs used to accumulate flow in / out of 12 V battery to zero. Unfortunately, the C-Max doesn't have the normal 12 V battery symbol on the dash. So, without FORScan to validate, I guess you could do the procedure several times hoping that one made no entry mistakes in at least one manual battery age reset.

homestead Posted February 16, 2021 Report Share Posted February 16, 2021 You can turn off the car with the radio on and time the amount of time until the radio shuts down. If it’s about 10 minutes then success. Quote Link to comment Share on other sites More sharing options...

For example, when my battery was failing a month ago and SOC showed 0%, the shutting down message would come up immediately upon startup. I would charge the battery back up full which was around 60 % and upon startup the message would not appear. After the frequency of getting the message on startup increased to virtually every morning, Ford Quick Lane upon testing found the battery wouldn’t hold a charge. The battery was physically 65 months old but I reset it twice, the latest being 4/3/2020. The SM indicates that If SOC < 40%, a power saving algorithm is trigged to mitigate power draw from non-essential load but goes no further into the description. So, if SOC is less than 40% (could be lower), the timeout could be less than 10 minutes. Quote Link to comment Share on other sites More sharing options...
13max Posted February 28, 2021 Report Share Posted February 28, 2021 I did unfortunately did not do this(reset the battery) three years ago on my 2013 Energi. Original lasted for 5 and bit years. Do you think if I did this now for a battery that is 3 years old? Its gone through a few discharges already this winter. Current specs in Forscan says my battery is 7 years old.

Not only is there no battery light, the car doesn't seem to notice if the battery is missing - I jump-started my C-Max and drove it without a battery installed, and there wasn't a single peep of concern on the instrument panel! I also used the flash-lights-pump-pedal procedure, and later bought FORScan Lite for IOS and verified that it had worked. Lots of data there to have fun with!

Very interesting and good to know. Easy to believe though, since in "ready to run" mode the DC-DC converter provides all 12V power from the HVB and the 12V battery only gets charged.

Lacienega Posted November 23, 2021 Report Share Posted November 23, 2021 I got the free forscan app for windows and reset my battery monitor since I've got a new battery... but I don't see how many days it had or has.

A bit late on this one and more of an obvious/common sense kind of thing but it still shouldn't be recommended to run with no 12v battery even if the car doesn't complain, regardless of whether it is a traditional ICE vehicle or a hybrid with a DC-DC converter. The biggest benefit of the 12v battery other than starting the vehicle is acting as a smoothing capacitor of sorts and keeping voltage spikes in check when high loads kick on or off. And there's quite a few in modern vehicles. Not running with the 12v battery can leave room for voltage spikes and surges to wreak havoc on expensive modules in the vehicle. The DC-DC converter may have the benefit of having some components on the 12v side for this, but until someone has torn it down to confirm, I wouldn't bet the multitudes of expensive modules on it.

Be aware there are two battery age PIDs available. One for the 12v and one for the HVB. If memory serves, the HVB is counted by months and the 12v battery is counted by days.

I have nothing for the 12v battery. Maybe I'll scan again later. Quote Link to comment Share on other sites More sharing options...
cr08 Posted November 23, 2021 Report Share Posted November 23, 2021 Make sure you aren't restricting yourself to a given module like the BECM. That's only for the HVB. The 12v battery PID is going to come from the BCM/BodyCM. Quote Link to comment Share on other sites More sharing options...

Olena Posted July 12, 2023 Report Share Posted July 12, 2023 (edited) Ford c-max plug-in hybrid 2017. The battery was dead and replaced. When they changed, they de-energized the car completely. Now the plug-in system does not allow to start the engine. The screen shows that the car is charging and it is not possible to start it. Gear lever locked in park If you select "no" in the menu "Vehicle Plugged In?" , the car starts and drives. The "engine" and "key" icons remain. Help me please. How to fix? I am in Germany now. USA car. Edited July 12, 2023 by Olena Quote Link to comment Share on other sites More sharing options...
