I have quite a few codes showing on this car and some of them seem related to each other. Has anyone seen anything like this? It almost seems like something is unplugged somewhere. Here are a list of the codes:

IPC DTC B1004 Keep Alive Memory (KAM
IPC U1000 Class 2 Communication Malfunction

PCM P0410 Secondary Air Injection (AIR) System
PCM P0463 Fuel Level Sensor Circuit High Voltage
PCM P1571 Traction Control Torque Request Circuit
PCM P1644 Traction Control Delivered Torque Output Circuit
PCM U1040 Loss of Class 2 Communications with ABS

RSS C0635 Left Front Normal Force Circuit Malfunction
RSS C0640 Right Front Normal Force Circuit Malfunction
RSS C0710 Steering Position Signal Malfunction

SDM U1040 Loss of Class 2 Communications with ABS

What I couldnt find-

DDM B3832
DDM B3833

The traction and brake lights are of course illuminated on the dash. I have a 2000 Seville Parts car that I can take parts off to get these codes to go away. I was also taking out the dash pad and now only heat blows through the top vents :(

Thanks for any help fellas..

I also have some parts left off a 2000 STS. If anyone needs anything, holler...

it would be very helpful to include whether the code is Current or History -

your abs/traction control problems
could all be related to a faulty/dirty EBCM plug or ground -
