Troubleshooting Section
B. Check all of the hold down clamps for the harness
in order to verify that the harness is properly
clamped. Also check all of the hold down clamps
for the harness in order to verify that the harness
is not compressed by the clamp. Pull back the
harness sleeves in order to check for a flattened
portion of wire. The flattened portion of wire is
caused by the clamp that holds the harness.
Expected Result:
The wires are free of abrasion, nicks, or cuts and the
harness is properly clamped.
Results:
•
OK – Proceed to Test Step 6.
•
Not OK – Repair the wires or replace the wires,
as required. If the fault has not been eliminated
proceed to test step 6.
Test Step 6. Check Connectors for
Moisture or Corrosion.

Connector seals
A. Ensure that the connector seals and the white
sealing plugs are in place. If any of the seals
or plugs are missing, replace the seal or plug. If
necessary, replace the connector.
B. Check all of the wiring harnesses in order to verify
that the harness does not make a sharp bend
out of a connector. This will deform the connector
seal and this will create a path for the entrance
of moisture.
Thoroughly inspect ECM connectors J1/P1 and
J20/P20 for evidence of moisture entry.
Note: It is normal to see some minor seal abrasion
on the ECM connector seals. Minor seal abrasion will
not allow the entry of moisture.
