Troubleshooting Test Steps
4. Perform a Pull Test on Each Wire Terminal Connection
A. Ensure that the locking wedge for the connector is installed cor-
rectly. Terminals cannot be retained inside the connector if the lock-
ing wedge is not installed correctly.
B. Perform the 30 N (6.7 lb) pull test on each wire. Each terminal
and each connector should easily withstand 30 N (6.7 lb) of ten-
sion 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.
5. Check Individual Pin Retention into the Socket
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.
6. Check the Locking Mechanism of the Connectors
A. Ensure that the connectors lock correctly. After locking the con-
nectors, 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.

Injector Code - Calibrate

Injector codes are seven digit alphanumerical codes
that are supplied with each injector. The code is
printed on the injector . The code is used by the
Electronic Control Module (ECM) to balance the
performance of the injectors.
The electronic service tool is used to load the injector
codes into the ECM.
The injector codes must be loaded into the ECM if
any of the following conditions occur:

Reconnect all connectors. If there are still active diagnostic
codes, refer to Troubleshooting, "Diagnostic Trouble Codes".
• An electronic unit injector is replaced.
i05867872
• The ECM is replaced.
• Electronic unit injectors are exchanged between
cylinders.
• A 630-2 diagnostic code is active.
If the ECM is replaced, the injector codes are
normally transferred to the new ECM as part of the
"Copy Configuration" procedure. If the "Copy
Configuration" procedure fails, the injector codes
must be loaded manually.
