Procedure
Check the fusing unit for correct installation (whether it is secured in position).
Check the open/close operation of the right door.
Check the connector between the fusing unit-relay CN3-BASEB CN10E for proper connection and correct as necessary.
Check the connector between the fusing unit-relay CN2-DCPS CN2 for proper connection and correct as necessary.
Check CPUB for proper installation and correct as necessary.
