Test Step 4. Perform a Pull Test on Each
Wire Terminal Connection

A typical example of the lock wedge.
(1) Lock wedge
A. Ensure that the locking wedge for the connector
is installed correctly. Terminals cannot be retained
inside the connector if the locking wedge is not
installed correctly.
B. Perform the 45 N (10 lb) pull test on each wire.
Each terminal and each connector should easily
withstand 45 N (10 lb) of tension and each wire
should remain in the connector body. This test
checks whether the wire was correctly crimped
in the terminal and whether the terminal was
correctly inserted into the connector.
Expected Result:
Each terminal and each connector easily withstands
45 N (10 lb) of pull and each wire remains in the
connector body.
Results:
•
OK – All terminals pass the pull test. Proceed to
Test Step 5.
•
Not OK – A wire has been pulled from a terminal
or a terminal has been pulled from the connector.
Repair: Use the CH11155 Crimp Tool to replace
the terminal. Replace damaged connectors, as
required.
Use the electronic service tool in order to clear all
logged diagnostic codes and then verify that the
repair eliminates the fault.

Test Step 5. Check Individual Pin
Retention into the Socket

Diagram for testing pin retention
A. Verify that the sockets provide good retention for
the pins. Insert a new pin into each socket one
at a time in order to check for a good grip on the
pin by the socket.
Expected Result:
The sockets provide good retention for the new pin.
Results:
•
OK – The terminals are OK. Proceed to Test Step
6.
•
Not OK – Terminals are damaged.
Repair: Use the CH11155 Crimp Tool to replace
the damaged terminals. Verify that the repair
eliminates the problem.
Use the electronic service tool in order to clear all
logged diagnostic codes and then verify that the
repair eliminates the fault.
STOP.
Test Step 6. Check the Locking
Mechanism of the Connectors
A. Ensure that the connectors lock correctly. After
locking the connectors, ensure that the two halves
cannot be pulled apart.
B. Verify that the latch tab of the connector is
correctly latched. Also verify that the latch tab of
the connector returns to the locked position.
Expected Result:
The connector is securely locked. The connector and
the locking mechanism is not cracked or broken.
