P0500 is an engine code (the P stands for Powertrain). This code sets because the ABS has a code, and the ABS signals the ECM to turn on the CEL.

You'll need to figure out what code is in the ABS mudule- the code(s) will start with a C (the C stands for Chassis). That should hopefully tell you where the problem is.

Whenever I get this code, it's because I ran the car on the lift to listen for a hub bearing noise, and the vehicle speed sensor gets cranky. In those cases it doesn't indicate a problem, but clearing the ECM will never work because the ABS code is still there. To clear the code for good, the ABS code needs to be cleared.
