Update. Sounds like there is an issue with the coolant lines for the batteries. There has been a leak which then in turn corroded the connections. The current plan would be to replace all of the battery modules. I asked if it was all 8 or 9’of then and the dealer thought so. Shipping from only a few hours away. Will see what happens…: I wonder if it was a result of the last recall and the module not being replaced correctly?

Has the coolant level been dropping in the overflow bottle, leading to topping it off in recent weeks?

Full details below. Replaced every battery in it. High voltage and 12v. Crossing fingers!

if anyone can interpret the codes or modules that would be cool.

Full details below.

Connector corrosion is not a good sign. Any fording of streams of mud?

Ha! Nope. I did do one of those automated car washes after I picked it up after the CAS HVB recall. i think they thought it was due to a coolant line leak?

Any temperature warnings on the dash due to the low battery coolant ??

I picked it up from the Recall repair, drove it 3 hours home, then parked it for a week while on a work trip, then went to turn it on and triggered about 20 faults. Ironically, low coolant didnt seem to be one of them.

It appears Module 2, and often Cell 18, are the location for HV battery issues.

Hi there! I can look into your Lightning's error message concern on my end. To get started, could you please send a private message over with the name/location of your local Ford dealer and your Lightning's VIN?
