4. Inspect control harness assembly (2) at location (AA) and hose assembly (3) at location (BB) for rubbing and or fouling on the DEF Tank Cover (See Image 1.4.1). If either item is damaged, replace both assembly (2) and (3).
396-3862 Control Harness Assembly (2) is compatible with serial numbers equipped WITHOUT a DEF Quality Sensor (FMC1-00772). 524-5527 Control Harness Assembly (2) is compatible with serial numbers equipped WITH a DEF Quality Sensor (FMC00773-Up).
Hardware (C) holding the DEF Module Group to the fuel tank and clamp (E) holding DEF Fill Hose (D) to the tank will need to be loosened to reposition the DEF Module Group to access control harness assembly (2) and hose assembly (3).
