Date: March, 1998
Subject:
Various Driveability Conditions
(Repair/Secure Wire Harness at PCM)
Model:
1997 Chevrolet Corvette
Condition
Some customers may report one or more driveability conditions which may or may not set a Malfunction Indicator Lamp (MIL) or a Diagnostic Trouble
Code (DTC).
Cause
The service loop of the wire harness for the PCM may be incorrectly routed. The harness may rub at the top front corner of the PCM (shown on Page
6-942 of the Service Manual, Volume 3). This condition was corrected in production in May, 1997 by adding additional conduit and improving the
harness routing.
Correction
Repair any chaffed or cut wires following the instructions in Section 8 of the Service Manual. Add additional tape or conduit to the wire in the damaged
area and secure the harness to prevent any further damage.
