Default Low Voltage Error - Need Help!

Okay,

My car had been flashed with Cobb AccessECU Stage 0 or 1 map before I purchased the car.

I just purchased the Cobb AccessPORT and it arrived today. I went to marry the AccessPORT to the car and received an error message.

I connected the two tester connections to one another and put in the blue 2002 connector and went through the process.

Hooked up the accessport cable into the OBD-II port and started to marry the ecu. It said flashing and got to about 58% last time I had checked. When I came back I had the Error Low Voltage Check Connection message and as far as I could tell everything was connected well. I unplugged the cable, turned the car to off and unplugged the 2002 connector and the tester connectors. I went to start the car back up and the electrical things come on, but the car won't turn over.

Cobb told me to send the ECU in to have it analyzed but I have no friggin idea what its going to cost. I really don't want to be without the car since I have no other mode of transportation and don't know how long shipping it there and back will be, along with not knowing the cost of repair if there is a problem.

I wanted to go buy a new optima battery, install it and try to go through the process again but the guy at Cobb said that that might damage the ECU at this point, and if its salvageable at this point, now is the time to salvage it.

What the **** am I supposed to do?

How much is a new ECU going to cost me?

Interuptions in the flash process fry ECUs. Sounds like yours is toast. I recieved the same idential error message before, but realized in my haste I forgot to plug in the square connector. Thankfully the flash process did not initiate. Maybe that connector was bad and failed during flashing. Check ebay for and classified for stock ECUs.

Stumbled across this old post, when I was trying to figure out what I was doing wrong to get the Low Voltage Error. In my case the voltage was 5.0XXXX. Suspiciously close to line voltage for USB devices and no where near possible for a vehicle that can still crank its starter.

I took it back to the shop (PDX Tuning) that I bought it from to swap out dongles...problem solved.
