ACTION
Follow the service procedure outlined below to address the customer concern.
SERVICE PROCEDURE
Replace the lumbar strap following the lumbar procedure in the Workshop Manual (WSM), Section 501-10. DO NOT remove the cable from the lumbar adjuster. New service parts have been released and the cables should be disconnected and reconnected at the lumbar strap.
Strap Replacement Procedure:
1. Release the two (2) lumbar spring clips from the backrest frame and remove the lumbar. Refer to WSM, Section 501-10 for more details.
2. Cut strap to allow removal of the cable in six (6) places while being careful not to damage the cable. (Figure 1)
3. Insert cable through zip tie loops and through the two (2) cable guides on the new lumbar strap. Ensure that the cable is held by the two (2) hooks. (Figure 2)
4. Snap the cable end and cable conduit end into strap. (Figure 3) Verify that both fittings are properly inserted by pushing on the fittings with the flat sur[ace of a standard screwdriver. After completing this, make sure that tabs are adequately engaged by pulling them back over the fitting with a scratch awl or small screwdriver.
NOTE
ON FUSION AND MILAN VEHICLES, THE CABLE DIE CAST MUST BE SNAPPED INTO THE STRAP NEAR THE BLUE ATTACHMENT WIRE AND THE OUTER CONDUIT END MUST BE SNAPPED IN TO THE STRAP NEAR THE BLACK CURVED ATTACHMENT WIRE.
5. Zip ties on both the die cast end fitting and conduit end fitting can now be pulled tight and the excess slack can be cut off. (Figures 4 and 5)
6. To install the lumbar strap assembly, reverse the removal procedure.
NOTE
THE LUMBAR ATTACHMENT WIRES MUST BE RUN IN AND BACK OUT OF THE LANCE TABS ON THE BACK FRAME. (Figure 6)
7. Install the front seat and repower the SRS. If a passenger seat has been serviced, do not prove out the SRS at this time. For additional information, refer to WSM, Section 501-10.
