4. From the bottom of the PDC housing, remove the relay cassette from the PDC.
CAUTION: Do not remove the wiring and terminals from the terminal cavities of the faulty PDC relay cassette at this time. Refer to the
Assembly procedure that follows for the proper procedures for transferring the wiring and terminals to the replacement PDC relay cassette.
INSTALLATION
1. Move the faulty PDC relay cassette with its wiring away from the bottom of the PDC housing far enough to allow the replacement relay cassette to
be installed into the PDC.
2. Using the faulty relay cassette as a guide, be certain that the replacement relay cassette is correctly oriented before installing it into the PDC
housing.
3. From the bottom of the PDC housing, align and insert the replacement relay cassette into the PDC. Press the relay cassette up into the PDC until
both of the latches are fully engaged.
CAUTION: Proper care must be taken to be certain that the wiring and terminals from the faulty PDC relay cassette are installed in the correct
terminal cavities of the replacement relay cassette. To prevent mistakes it is recommended that the wiring and terminals be removed from the
faulty relay cassette one cavity at a time, repaired or spliced as necessary, then installed securely into the correct cavity of the replacement relay
cassette. If you are not absolutely certain into which cavity a terminal should be installed, refer to Power Distribution in the index of this service
manual for the location of complete circuit diagrams covering the PDC.
