Service Procedure
NOTE: Perform this procedure on both front seats.
1. Remove the seat cover to access the SCMH and SCMG module. Refer to the Workshop Manual
(WSM), Section 501-10A.
2. Remove the harness shied to seat back frame retention clips and separate the plastic shield from the
harness to access the circuits.
3. Measure back 150 mm (5.9 in) from the edge of the plastic shield and mark the circuits to determine the
cut location. The finished harness must extend a minimum of 300 mm (11.8 in) beyond the edge of the
plastic shield. (Figure 1)
(1). The circuits for the left seat will run to the right side of the seat and the circuits for the right seat will
run down toward the floor.
NOTE: Do not use the butt connectors included with the pigtail kit for this repair. Each circuit must
be connected with solder and covered with heat shrink tubing.
