I was reading your question concerning the swap, I want to swap ecm's on two 94 vans but am concerned about damaging the good one. Does anyone have any experience with this swap and what was the result. I have a condition in one van where the voltage jumps up to around 17 volts the engine starts running badly then it may quit running or the voltage drops to 13.5v and it runs fine.

I noticed that nobody actually ever answered your original question IPD324. My husband just bought a PCM at a local salvage yard. The numbers or off but it did the trick and fixed the car which is a 96 dodge grand caravan that wouldn't start. My question is, was it expensive to reflash the PMC?
Hello,
I have the same codes coming up on my 2002 Sebring Convertible. I had not had any trouble or engine/trany work done since I got this car 2 years ago. Been running great.
The MIL came on a couple weeks ago, took it to my mechanic (who is a neighbor and good friend and owns a shop that does propane conversions and services hundreds of vehicles including cabs, police cars and emerg vehicles, and I know I can trust him 110%.
He cleared the codes but they came back a few days later, and are now showing more frequently. The MIL will go off after serveral restarts or clearing with the OBD2. My trany goes into limp but will be OK for 3-5 starts after it resets after about 5-8 starts. My guy told me to take it to the dealer. P0605 is a ROM error code. P0700 is a TCM fault. The Chrysler dealer said their scanner was not able to talk to the TCM and said they could try replace it for about $700. Well.. lets not just yet.
I also have a 96 Caravan that's had computer issues and I had the PCM (yes PCM) replaced a couple times. With the 2nd PCM the MIL was staying on, but there were no faults. A wrecker in Toronto has a sale a few times a year where you pay $50 for access to an area of the yard of cars about 10years old or more, and can take anything you can carry. I grabbed 4 PCM's. I had different results with each, but I was able to just swap them without configuring/programming. I found a website of a auto computer supplier selling TCM's for $200 in Florida and they indicate they'll program it with your VIN, so I'm not sure if these have to have the correct VIN to match up with other Bus link devices to work properly.
I have also found recommendations like checking and cleaning grounds.
I would try swaping the PCM. I found TCM's go for about $50-70 so I might give that a try.
Good luck and let me know if you got yours fixed. ronkloiber at yahoo dot ca.
Thanks,
