Thursday, I wanted to take the car out for a drive. Took off the trickle charger, and car didn't crank (aka battery seemed dead). Didn't have time to think about it, so put the trickle charger back on and left.
Friday I tried again, same thing, so figured battery probably dead. Car was acting odd...rear lights flashing lightly, front lights on. I pressed the light button on then off and that ended that. I assumed it was because battery was really weak.
Today decided to swap the battery out, so took the battery out of the car and brought it to Autozone. When they initially tested it, it showed a little over 9V. They tried to charge it over 2 hours and found that it wasn't holding charge.
Bought a new battery, and put it in.
Go to try and start the car, and I get "Comms Failure EMS" showing in the right display. Car won't let me crank.
Plugged in the Foxwell and got the following codes:
U0100: Lost communication with ECU
P1613: Forced Mechanical Limphome Position OR secondary air injection system
I tried to clear the codes, but I'm not sure if the Foxwell worked as it didn't seem to clear it.
What the heck did I do?
Tried to search around and only found where people tried to jump the car with the key in the ignition. Only thing I can think of is I may have tried to start it with the trickle charger connected (can't remember).
Thought I'd see if anybody had any ideas before scheduling and towing to the dealer. I'm fearing the worst in my head right now
