EEC5 runs a protocol called SCP (standard corporate protocol)
A version of this WAS included in the OBD2 standard called J1850.

Beware, NOT all scan tools can read FORDS as they use this unique J1850 protocol
and usually only more expensive/full featured tools will read them.

You cannot reset codes on and EEC5 ecu by removing power.
Can ONLY be removed with proper scan tool.
