ISSUE
Various driveability or engine performance concerns may be present. These concerns could be:

^ Hard to start

^ Engine hesitation

^ Rough or unusual rolling idle

These may be caused by an electrical wiring harness that is being chafed by the under carriage around/under the driver's seat area.

ACTION
Inspect affected wires and determine if chafe is present. If chafe is present, refer to the following Service Procedure for details.

SERVICE PROCEDURE

1. Inspect wire harness and inspect for wire chafing. If chafing is present, proceed to Step 2. If not, proceed with other normal electrical/driveability diagnostics for repair.

2. Remove wire harness interface bracket (connector retaining bracket-14A206-(driving board bracket))

3. Verify Mastic Insulator Patch (F87Z-1310484-AA) is present. If mastic patch is not present, proceed to Step 4. If patch is present, proceed with other diagnostics.

4. If wire chafing is evident between rear of connectors and the start of convolute, repair damaged wire with known wire repair service procedures. Protect repaired wires by applying Flex Wrap (F2TZ-18K459-AA) to affected area. Secure flex wrap with electrical tape or equivalent.
