Condition Code: X4
Service Procedure
NOTE: Perform this procedure on both front seats.
- Remove the seat cover to access the SCMH and SCMG module. Refer to the Workshop Manual (WSM), Section 501-10A.
- Remove the harness shied to seat back frame retention clips and separate the plastic shield from the harness to access the circuits.
- 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.
Figure 1
(1). Cut, solder, and heat shrink each circuit one at a time following the instructions included with the kit. (Figure 2)
Figure 2
- Wrap the new wiring with Coroplast tape or equivalent from the plastic harness shield to the connector.
- Install the plastic harness shield and secure with the 4 retention clips.
- Measure 105 mm (4.13 in) from the back for the new harness connector shell and place a mark on the new harness.
- Connect the new connector to the module and loop the harness above the module placing the mark on the harness applied in Step 7 on the top of the module next to the tube connections. (Figure 3)
Figure 3
- Secure the new harness to the module body using a minimum 280 mm (11 in) long zip tie.
- Reinstall the seat back cover. Refer to the WSM, Section 501-10A.
