The following items are not working on my 2002 Ford F250 4x4 Crew Cab. The door ajar light stays on all the time. The interior lights stay on all the time. The automatic door locks no longer activate when you start driving as they used too. The power windows and radio do not remain powered for the five mintue delay after the ignition is turned off as they previously did. I do not have an alarm on this truck. I have hooked a superchip diagnostic programmer up and I get the error #603 internal control module KAM error) I have found a website that explains this code( faulty PCM InOpen PCM pin, disconnect B+,ternal control module KAM error) (Huh?) How can I fix this problem. I have tried spraying DW40 in the latches as some suggets and it hasn't worked.
