The pin-outs for the PCM were shown representing the incorrect engine for the pin-out. To correct, change "L4" labels to "V6 VIN M" and change "V6 VIN M" labels to "L4 VIN D". There are three pin-outs for each engine that require this change.
Page 8A-202-28
The description for cavity "10" of the PCM, C2, was omitted. To cavity "10", add "DK GRN" under "WIRE COLOR", "83" under CIRCUIT NUMBER, and "Cruise Control Signal-Disengage" under CIRCUIT FUNCTION.

The cavities should appear as shown for the PCM, C3, for the L4 VIN D. L4 VIN 3 should be changed to L4 VIN D throughout Section 8A.
