Repairing Bus Wiring
WARNING: This page is about a different car, the 2001 Lincoln Continental. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
Following procedure must be used to ensure proper repair is performed on bus wiring. Bus wiring is sensitive to moisture and oxidation and must be properly sealed to ensure proper operation of the module communications network. Regular heat shrink tubing is NOT sufficient, heat shrink tubing containing hot melt wax is required.
- When performing a repair on bus wiring, ensure wires on bus are twisted at a rate of 33-40 winds per 3.3 ft. (1 m). Twists should start within approximately 4.9" (124 mm) from any harness connector. Use only 20 AWG standard wire gauge for repairs.
- If performing a splice in wiring, strip .75" (19.0 mm) of insulation from one wire and 1.50" (38.1 mm) of insulator from other wire. Perform STEP 1 in illustration. See Fig 1 . Place hot melt wax type heat shrink tubing over one wire.
- Twist stripped portion of wires together. Solder connection using resin core RMA solder. DO NOT use acid core solder. Bend wires to allow installation of heat shrink tubing. Perform STEP 2 in illustration. See Fig 1 .
- Position heat shrink tubing over splice area. Using heat gun, evenly heat shrink tubing until wax flows from both ends of heat shrink tubing.
