Trouble code 173700

Hello, hopefully you can shed some light on this. A few months ago the malfunction light came on and I checked for the code using the digital odometer. The code it gave me was not a normal code with P and 4 numbers. It flashed "173700" 3 times, then "done".

Within a few days after the light first came on, the battery died. This was either the sealed factory Chrysler battery (or a dealer replacement) which had lasted 11 years, or at least the 3 1/2 years I owned the car. I replaced the battery and since then I have had no problems except that the malfunction light stays on, with this code.

I have tried to reset the computer by disconnecting the battery and draining the residual charge by holding down the horn, and leaving the battery disconnected overnight. However, within 100 miles or so the light comes back on. I am not experiencing any kind of electrical problems with the car, and everything else seems to be working ok.

I have seen this 173700 code asked about in a couple of questions online, but I have not seen any answers. I called a Chrysler dealer and he had no idea what this code might be. Maybe the computer needs to be replaced?

Any light you could shed on this would be greatly appreciated, and even if you are unable to help me, thank you for your time. Sam
