8.
Disconnect the two (2) rear fuel injector connectors and roll the FICM harness over to view the underside of the two (2) injector harness take-outs
leading to the FICM.
9.
Inspect the underside of the injector harness in the two (2) areas noted in the illustration. See Figure 4.
NOTE:
The harness is constructed of a bundle of insulated copper wires wrapped in a grounded silver-colored shield (much like heavy gauge
aluminum foil), then covered with a wrapping of black vinyl tape.
^
If the harness is either NOT chafed or only lightly chafed but the copper wire strands ARE NOT visible (outer vinyl tape and possibly the
silver-colored shield is worn through), the Harness Protection Kit 4C3Z-14A099-A must be installed. Proceed to FICM Harness Protection
Kit Installation in this Attachment IV.
^
If extensive chafing has occurred which has exposed the copper strands, the harness must be replaced. Do not attempt to repair a chafed
harness if these conditions are found. Proceed to FICM Harness Replacement in this Attachment IV.
