This section presents standalone replacement
operations which can be done in-chassis without
a complete engine overhaul. These operations
include:
앫 OIL PUMP REPLACEMENT (IN CHASSIS)
앫 CRANKCASE VENTILATION (CCV)
SEPARATOR REPLACEMENT
앫 TURBOCHARGER SMART REMOTE

Due to the Engine Electronic Control Unit (EECU)
self-learning capability, it is necessary to reset
learned EECU parameters after servicing some
engine-related components. This allows the
EECU to learn the new component's behavior.
After servicing is complete, perform the “Learned
Data Reset” located in VCADS.
