Question about Cars & Trucks
9400 is the brake pedal switch - and often just that switch.
400c is the evaporative emissions system - often a gas cap that isn't screwed on tight, but it could be a leaky hose, or emissions pump etc.
928c is the steering wheen control module - either you need to replace that, or it's the power steering module.
720A is the immobilizer and means that the computer doesn't see or get the right code from the immobilizer. I believe this is the unit that senses that you have the right key inserted before starting.
E003 is usually a DIM (driver information module) fault, basically a problem with the cluster. A software reload for that might fix it, or replacement of the instrument cluster.
If all of these errors happened at the same time, I would say that the ECM has the hiccups. You can either find the ECM fuse inside the driver side door fuse box (open door, open lid to fuse box, remove fuse... 25? there's a diagram on the lid).
Otherwise remove the negative battery cable in the trunk for an hour or so and then turn the ignition to Pos II and then reconnect it. That should clear the brain.

Hi RS, You'll need to have the service reset carried out with someone with a scanner. That will solve the problem! Regards Johngee10
