I did some more research. There are only 3 things that can cause this issue.
1) Your KAM PWR Circuit is open. Get a wiring diagram for the ECU and find out which pin is your KAM PWR Circuit. Then get a DVOM and measure voltage with the read lead on the Pin and the black lead on ground. You should have voltage. If not you have an open on that Circuit.
2) You fried the KAM in your module. Replace Module.
3) A sensor your KAM uses is not installed on an 03, but is installed on an 05. I don't know what it would be, but you would need to replace the module.
Put an 03 Module in it would be your best bet.
