Connection Procedure Using Crimp Terminal
CAUTION:
- Always use the special service tool (49JP 03 001) when performing this procedure. If a similar tool other than the special service tool is used, the possibility of a poor connection occurring due to insufficient crimping is high even though it may appear that the crimping was done successfully.
- Select the appropriate crimp terminal and the crimping area of the special service tool according to the thickness of the wiring harness to be repaired.
Size (mark) Outer diameter 1 Compatible wiring size Crimping area of special service tool 1 S 3 mm {0.1 in} 0.5-1.0 sq 1.25 M 4 mm {0.2 in} 1.25-2.5 sq 2 - Squeeze the grips tightly until the ratchet of the special service tool detaches and open the handle of the special service tool.
- Place the appropriate crimp terminal on the crimping area of the special service tool and secure the crimp terminal by lightly squeezing the grips to a level that the crimping terminal does not deform.CAUTION:
- Set the cutter blade of the special service tool inside the scribed line (cutter blade position indicator line of special service tool) on the crimp terminal.
- Insert the wiring harness to be connected into the crimp terminal until it reaches the contact point inside the terminal.CAUTION:
- Verify that all the cores have been inserted without buckling.
- Crimp the crimp terminal completely by squeezing the grips of the special service tool tightly until the ratchet detaches.
- Pull on the connected wiring harness to verify that the wiring harness does not pull out of the crimp terminal.
- Perform the same procedure from Steps 3 to 6 for the opposite side.
- Set the heat-shrinkable tubing to the connection area so that it is centered and shrink the heat-shrinkable tubing at a temperature of approx. 100°C {212°F} using a drier until the plastic melts on both ends.CAUTION:
- Completely shrink the heat-shrinkable tubing to the wiring harness leaving no gaps.
- Perform the work being careful not to melt the insulation of the wiring harness due to excessive heat.
