1Make sure you identify the faulty PCM correctly from the two modules installed.
2Lift latch which secures the power supply cord.
3Switch off and disconnect the power supply cord.
4Remove the two thumbscrews on the right and left sides of the unit.
5Firmly grip the handle on the bottom of the unit and withdraw the PCM.
