I recently tried to hook up a new battery one of those lithium Ion antigravity batteries for my 2017 Mustang. I screwed up and reversed the terminals. The car drove for 1 min but then conked out. I then put a brand new lead acid in to the car and it drives howerver keep seeing " Service charging system now.
I tested the battery terminal with a multimeter and it is 12.2 volts when car is off. when i turn the car engine on it goes to 11.5 which seems strange as it goes even lower.
I reset the battery BMS by pulling the headlight lever and pushing the brake 3 times and it reset. Still the " Service charging system now. error comes on.
I hooked up an obd code reader and it says 1 error. The error reads
p068a
Stored
ECM/PCM Power Relay De-Energized
Performance- Too Early
Could I of short circugited something when I reversed the battery as it did spark and smoke from the positive terminal when I did that.
I reset the code with the obd scan rtool and it says I have no errors but the battery light is still on and " Service charging system now still shows.
Does anyone know what fuse might of blown or if I just need to replace the PCM fuse?
Please guys its so urgent and need your advice.
Much appreciated, I look forward to any and all of your help.
