Results:
• OK – The connectors are in good repair. Proceed
to Test Step 7.
•
Not OK – The connector’s locking mechanism is
damaged or missing.
Repair: Repair the connector or replace the
connector, as required.
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 7. Check the Screws on the
ECM Connectors (64 way)
Visually inspect the screws for the ECM connectors.
Ensure that the threads on each screw are not
damaged.
A. Connect the ECM connectors.
a. Use a 7 mm Torx screw in order to retain each
of the ECM connectors.
b. Tighten the two Torx screws for the ECM
connector to the correct torque of 5.0 ± 1.0 N·m
(44 ± 9 lb in).
Note: If the threaded insert in the ECM is damaged,
the ECM must be replaced. Refer to Disassembly
and Assembly, “Electronic Control Module - Remove
and Install”.
Expected Result:
The ECM connectors are secure and the Torx screws
are correctly torqued.
Results:
•
OK – The ECM connectors are secured. Proceed
to Test Step 8.
•
Not OK – The screws for the ECM connectors are
damaged.
Repair: Repair the connectors or replace the
connectors or screws, as required.
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 8. Perform the “Wiggle Test” on
the Perkins Electronic Service Tool (EST)
A. Select the “Wiggle Test” from the diagnostic tests
on the Perkins Electronic Service Tool (EST).
B. Choose the appropriate group of parameters to
monitor.
C. Press the “Start” button. Wiggle the wiring harness
in order to reproduce intermittent faults.
If an intermittent fault exists, the status will be
highlighted and an audible beep will be heard.
Expected Result:
No intermittent faults were indicated during the
“Wiggle Test”.
Results:
•
OK – No intermittent faults were found. The
harness and connectors appear to be OK. If this
test was required as part of another procedure,
return to that procedure and continue testing. If
this test has resolved the fault, return the engine
to service. STOP.
•
Not OK – At least one intermittent fault was
indicated.
Repair: Repair the harness or the connector.
Use the electronic service tool in order to clear all
logged diagnostic codes and then verify that the
repair eliminates the fault.
STOP.
