Supersedes Technical Service Bulletin Group 01 number 12-63 dated December 17, 2012 for reasons listed below.
Affected Vehicles
Condition
MIL on, with one or more of following DTCs stored in the 01 (Engine Control Module):
^ P113700 or P112700 (System rich, Bank 1)
^ P113900 or P112900 (System rich, Bank 2)
Technical Background
Under extreme driving conditions, such as a driving profile of mainly short distance (stop and go) driving high crankcase pressure can lead to the
above described DTC codes. By changing the crankcase pressure valve to a lower operating pressure this condition can be improved and eliminate
the mentioned possible DTC codes. Along with the crankcase pressure being lowered, a new ECM software level is required to compensate for new
crankcase pressure.
Production Solution
Crankcase pressure reduction starting with model year 2013.
Service
1. Replace crankcase pressure regulating valve using Repair Manual instruction provided in Elsa Web (Engine >> Engine Mechanical >> 17
Lubrication >> Removal and Installation >> Cover with Oil Separator) with part number 06E103547H.
Tip: Reuse collected oil.
2. Follow all instructions in the attached TSB 2011732 00 Software Version Management (SVM), operating instructions.
3. Update the 01 (Engine Control Module) using SVM action code as listed in the table above if necessary.
