Test Step 1. Check
for Connector Damage
A. Remove power from the ECM.
B. Thoroughly inspect the ECM connector J2/P2.
Inspect the con
nectors for the right rail and for
the left rail. Refer to the diagnostic functional
test Troubleshooting, “Inspecting Electrical
Connectors” f
or details.
C. Perform a 45 N (10 lb) pull test on each of the
wires in the E
CM connector that are associated
with the circuit.
D. Check the all
en head screw on each ECM
connector for the proper torque. Refer
to Troubleshooting, “Inspecting Electrical
Connectors”
for the correct torque values.
E. Check the harness and the wiring for abrasion
and for pinch
points.
Expected Result:
All connectors, pins, and sockets are completely
coupled and/or inserted, and the harness and wiring
arefreeofc
orrosion, of abrasion and of pinch points.
Results:
•
OK – The connectors and wiring are OK. Proceed
to Test Step 2.
•
Not OK – There is a problem in the connectors
and/or wiring.
Repair: Repair the connectors or wiring and/or
replace the connectors or wiring. Ensure that all of
the seals a
re properly in place and ensure that the
connectors are completely coupled.
Verify tha
t the repair eliminates the problem.
STOP.
Test Step 2. Check for Logged Diagnostic
Codes
A. Connect C
at ET to the service tool connector.
B. Restore power to the ECM.
C. Check for logged diagnostic codes for the injector
solenoids on Cat ET.
Expected Result:
No 1-05 to
16-05 or 1-06 to 16-06 are logged.
Results:
•
OK –No1-05to16-05or1-06to16-06are
logged. Proceed to Test Step 3.
