Expected Result:
The harness, connectors, and seals are in good
condition. There is no evidence of moisture in the
connectors.
Results:
•
OK – The harness, connectors, and seals are in
good condition. Proceed to Test Step 2.
• Not OK – A fault has been found with the harness
or the connectors.
Repair: Repair the connectors or the wiring, as
required. Ensure that all of the seals are correctly
installed. Ensure that the connectors have been
reattached.
If corrosion is evident on the pins, sockets or the
connector, use only denatured alcohol to remove
the corrosion. Use a cotton swab or a soft brush
to remove the corrosion.
If moisture was found in the connectors, run the
engine for several minutes and check again for
moisture. If moisture reappears, the moisture is
wicking into the connector. Even if the moisture
entry path is repaired, it may be necessary to
replace the wires.
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 2. Check the Wires for Damage
to the Insulation
A. Carefully inspect each wire for signs of abrasion,
nicks and cuts.
Inspect the wires for the following conditions:
•
Exposed insulation
• Rubbing of a wire against the engine
•
Rubbing of a wire against a sharp point
B. Check all of the fasteners on the harness and the
strain relief components on the ECM in order to
verify that the harness is correctly secured. Also
check all of the fasteners in order to verify that the
harness is not compressed. Pull back the harness
sleeves in order to check for a flattened portion
of wire. A fastener that has been overtightened
flattens the harness. This damages the wires that
are inside the harness.

Expected Result:
The wires are free of abrasion, nicks and cuts and
the harness is correctly clamped.
Results:
•
OK – The harness is OK. Proceed to Test Step 3.
• Not OK – There is damage to the harness.
Repair: Repair the wires or replace the wires, 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 3. Inspect the Connector
Terminals
A. Visually inspect each terminal in the connector.
Verify that the terminals are not damaged.
Verify that the terminals are correctly aligned in
the connector and verify that the terminals are
correctly located in the connector.
Expected Result:
The terminals are correctly aligned and the terminals
appear undamaged.
Results:
• OK – The terminals are OK. Proceed to Test Step
4.
•
Not OK – The terminals of the connector are
damaged.
Repair: Repair the terminals and/or replace the
terminals, 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.
