FIELD SERVICE CAMPAIGN
Subject: Field Service Campaign 14M2

S60 Export Injector Harness Replacement

Issue Involved
Detroit Diesel Corporation (DDC) has determined that some export S60 engines will require
replacement of the injector harness. The injector harness wire insulation may crack,
causing poor engine performance and fault codes. Replacing the injector harness will
prevent performance issues and fault codes that may result in customer dissatisfaction.
There are approximately 273 engines affected by this Field Service Campaign.
