Air Suspension Overlay

NOTE:
  • This repair applies to L320/LS, L405/LG and L494/LW models only.
  • Some variation in the illustrations may occur, but the essential information is always correct.

If after diagnosis the height sensor requires replacement and the area of wiring damage is localized to the height sensor connector, this overlay harness should be used,

  4. Remove the wiring harness insulation as required.
    NOTE:
    • It is advisable to cut only 1 of the wires at a time and to stagger each joint to allow easier insulation.
    • The colours of the overlay harness may vary.
  5. Cut the wire on the vehicle harness leading to cavity 1 of the height sensor connector in a suitable position. Then remove 10 mm (0.39 inch) of insulation. For connector location and pin identification, refer to the relevant connector:
    • L320 - C1696/7/8/9
    • L405/L494 - C1CD10/11/12/13

    In the Connector Details section of the relevant Electrical Library.

  7. Using the inline connector supplied and the correct crimping tool set to the correct jaw size from the harness repair kit, crimp the connector to the wire.
    NOTE: The overlay harness should be cut so that there is no additional length added to the overall length after repair.
  8. Select the appropriate wire on the overlay harness that also goes to cavity 1 of the new connector. Cut the wire to the correct length and remove 10 mm (0.39 inch) of insulation.

  9. Insert the overlay wire into the connector and crimp in place.
    CAUTION: Care must be taken when using the hot air applicator to avoid damage to surrounding areas.

  11. Do the same process for the wires in cavities 4 and 5 of the connector. For connector location and pin identification, refer to the relevant connector:
    • L320 - C1696/7/8/9
    • L405/L494 - C1CD10/11/12/13

    In the Connector Details section of the relevant Electrical Library.

  12. Discard the damaged connector/section of the harness.
