Service bulletin 112014

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

1102152018-11-13. Service bulletin. SUBJECT Deleting DME Adaptations After Crankshaft Sensor-related Repairs. The erroneous misfire faults are stored, and the Service Engine Soon light (MIL) illuminates The ISTA Service Function to delete the DME adaptations fails to clear the crankshaft incremental wheel adaptation, depending on the current DME software version. This adaptation must be cleared whenever the following repairs are made: 1. Replacement of the crankshaft position sensor 2. Replacement of the incremental sensor wheel on the crankshaft 3. Replacement of the crankshaft 4. Replacement of the crankcase (block) with pistons 5. Replacement of the engine assembly Due to slight tolerance differences with the new replacement hardware and the original learned crankshaft position, values could cause cylinder balance calculation errors by the DME. DME software (the incremental wheel adaptation cannot be cleared)
