SERVICE PROCEDURE
NOTE
THIS PROCEDURE ONLY APPLIES IF DAMAGE HAS BEEN IDENTIFIED AT THE SPECIFIC CONNECTOR AND PIN. IF DAMAGE IS
NOT VISIBLE AT THE SPECIFIC CONNECTOR AND PIN, THIS PROCEDURE DOES NOT APPLY AND CONTINUE WITH NORMAL
DIAGNOSTICS IN THE APPROPRIATE WORKSHOP MANUAL.
Refer to Workshop Manual (WSM), Section 501-10 to gain access to the DCSM connector. Seat removal may be required.
Zephyr-MKZ:
If Connector C3305A is damaged at Pin M GD139 (BK-YE), then replace connector pigtail. The replacement pigtail will have an extra wire in Pin L
position. (Figure 1)
1.
Obtain Pigtail Kit. Strip the ends of the wires from Pins L and M, 1/4" (6.3 mm). Twist them together. Insert twisted wires into one end of a 12-10
gage butt splice. Using the approved splicing methods found in the Wiring Diagram (WD), Cell 5, crimp the butt connector.
2.
Strip the end of GD139 (vehicle harness side - ground) and insert into open end of the 12-10 butt splice (at Pin M). Using the approved splicing
methods found in the WD, Cell 5, crimp the butt connector and seal with shrink tubing.
3.
Continue to attach the rest of the pigtail wires to the vehicle harness, using the approved splicing methods found in the WD, Cell 5, crimp the butt
connector and seal (with shrink tubing). Wires from pins E and F will require 12-10 butt splice which is not included in the pigtail kit.
