DIAGNOSTIC STEP(s)
- Not Applicable.

REPAIR STEP(s)

1. Open the hood.
2. Disconnect the 76-way connector (1) from the IP/Center Chassis harness.

3. Starting at the IP connector, remove the wire loom from the harness to approximately 12” back from the connector.
4. Locate the A04-131-AAD wire from terminal 9 on the Center Chassis/IP connector. Using wire cutters, cut the wire
approximately 10.5” or 270 mm away from the connector body. On the wire leading to the IP connector, strip the wire insulation
back ¼”. Take the other cut end of the wire and fold it over. Slide on a heat shrink tube and shrink to cover the open end of the
wire.
5. Locate the A04-131-ABA wire from terminal 4 on the Center Chassis/IP connector. Cut the wire approximately 10.5” or 270
mm from the connector body and strip the insulation back ¼” on both ends of the cut wire.

6. Slide a 2-inch piece of heat shrink tube over the cut wires. Twist together the stripped ends of the A04-131-AAD wire from
terminal 9 and A04-131- ABA wire from terminal 4. Splice them together with solder, followed by heating the shrink tube to cover
the splice joint. Using a barrel style crimp splice of appropriate size for the wire, insert both ends of the wires into the crimp
splice until conductor hits the wire stop.

7. Using the CK90-66 crimping tool, crimp splice onto the wire. Ensure all the individual wire strands are inside the crimp
splice. Lightly pull on both ends of the wire to ensure a tight and secure connection exists.

8. Using rosin core 60/40 solder, begin tinning the solder to the crimp splice and allow it to flow into the crimp splice and fill all
voids.

9. Slide the heat shrink over the splice and apply sufficient heat using a heat gun to shrink the tubing over the splice and wires
(1). The adhesive should start to seep out of the ends, completely sealing the repaired area.

10. Re-cover the wire loom and reconnect the IP/Connector.
11. The completed wiring will reflect the diagram below.
