Final Unplugged results:
Summary: The truck charges the 12V battery from the HVB when it falls to 50% and goes into deep sleep mode. Once it enters deep sleep mode, the truck will no longer respond to FordPass as I expect it shuts down the modem module among others. The first time it did...
As many have said, it depends on how you will use the truck. If you plan on rolling in at 11pm in single-digit SOC regularly and need to be fully charged by 7am, the FCSP will do this. It sounds more like you are a normal driver who won't put 200-300 miles a day on the truck and a normal 40A...
On the topic of Wireless Phone charging - not a bad skip. The Lighting has it tucked up under the dash and phone GPS functions are weak at best in that location. I get goofy readings regularly on my old iPhone 11 and the same on my current iPhone 14. Installing a wireless charge pad up on top...
Agree SOC shouldn't change. To make the GOM more accurate, you need to set up a profile for each trailer you pull and be sure to select the right profile. The truck will adjust the GOM based on the actual power used to pull a trailer on that profile (mixing trailers on the same profile will...
Update to above. My truck has been unplugged for 2 days now. In less than 48 hours, the 12V battery dropped to 50%. I got two messages on my FordPass, and shortly thereafter, the truck charged the 12V battery to full.
Some notable items:
1) HVB climbed from 85% (my set charge level) to 86%...
I agree. It's going in for the Heated Steering add and tail light fix next week so I'll ask them to replace it. It is happening to many of us on both the Lightning and MME side. I hope Ford will fix the route cause (like charging the 12v from the HVB or EVSE when it drops below 60% instead...
I agree, it seems extreme. What year and how long have you had your Lightning? Mine sat on the dealer lot for 2 months initially as we negotiated my order pricing vs. dealer pricing. I expect that may have caused some premature wear on the 12v sitting in a state of discharge for a number of...
I had my electric panel upgraded a couple of weeks ago. I ran 2 full-size refrigerators, 1 full-size freezer, my internet modem, my 49" 4k TV, my computer, a computer monitor, my coffee maker (of course), and a toaster oven. All but the coffee maker and toaster were running for 7.5 hours and...
Thought - Why doesn't Ford let you select the power the truck requests in the charge settings? In the case above, selecting a 20A circuit on 120V, the truck would safely draw 16 Amps and would blow a 15 amp beaker but charge fine on a 20 amp - this may still be dangerous with the 120v Level 1...
If your truck is plugged in for more than a few days without turning it on for any substantial period, your 12V system will still shut down many components to conserve energy. This may have affected your initial SOC reading since it may not have tracked it when things shut down. On a couple...
The really depends on how you will use the truck.
I have an aftermarket mobile charger and use it pretty much weekly. The truck charges daily during the week on my fixed EVSE and on the weekends I travel either to my parents or to my marina and charge using the mobile charger on either a...
Since learning how the 12v battery charges/discharges, I never use Accessory mode - there is no need. Simply turn the truck on and no problems. Benefit - Air conditioning.
Would be good if Ford would tweak the parameters to charge the 12v battery from HVB before it gets low enough to...
I too own both an MME (since July 2022) and a Lightning (since January 2023) and neither vehicle has needed a trip to the dealer. Both have been extremely reliable. Some software glitches were ironed out earlier in the ownership of each but in each case for both the MME and Lightning, it was...
In case anyone is interested, I tracked my 12V battery for several days and I only saw it charge in 2 scenarios:
1) While the truck in "ON"
2) While the HVB is being charged on Level 2 station.
Even with the truck plugged in, the 12V battery would drop once the HVB charge cycle ended. From...
The dealer should have had this set up and working before you drove away from the lot. My FordPass was working before my wife drove her MME off the lot as well as my Lightning. This is standard delivery procedure for the dealer. You'll need to get the dealer to complete their sales process...
I would expect at some point the USA will allow the truck to be shipped with this active. We have it active already on delivery in Canada. Very nice feature.
