NOTE: Use this procedure when diagnostic testing suggests substituting PCM with known-good unit.

On models equipped with engine immobilizer system, acquire key cut from non-immobilizer key blank. Remove ECM/PCM from test vehicle. Install known-good ECM/PCM from donor vehicle into test vehicle. Tape donor vehicle's ignition key head-to-head to test vehicles temporary key. ECM/PCM will recognize code from donor vehicle's key and allow test vehicle to be started and tested.
