it means you have NO CODES when it says done, it's done looking for codes, and none came up. when you do have codes it will say the code, then say done

He's right you code free...

The P PCU is the Powertrain Control Unit AKA: Powertrain Computer Module.
PCM

The P ECU is the Engine Control Unit AKA: Engine Computer Module.
ECM

And communicate over the CCD network.
CCD Data Bus
