PDC Relay Cassete
REMOVAL
The Power Distribution Center (PDC) cover, the PDC housing lower cover, the PDC relay wedges, the PDC relay cassettes and the PDC B(+) terminal
stud module are available for service replacement. The PDC cover can be simply unlatched and removed from the PDC housing without the PDC being
removed or disassembled. Service of the remaining PDC components requires that the PDC be removed from its mounting and disassembled. Refer to
Wiring Repair in Wiring Diagrams for the location of the wiring repair procedures.
1. Remove the relay wedge from the PDC relay cassette to be removed.
NOTE: It may be necessary to remove relay cassettes that are not being serviced from the PDC housing in order to obtain sufficient clearance to
access the faulty relay cassette. The same service procedure is repeated as necessary to remove each of the interfering relay wedges and relay
cassettes from the PDC housing.
