Service bulletin A011473 2031458-
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.

NHTSA's summary
Supersedes Technical Service Bulletin Group 01 number 13-45 dated December 5, 2013. The MIL is on. DTCs are stored in the ECM. Under extreme driving conditions (such as short-distance, stop-and-go driving), high crankcase pressure can cause the DTCs to appear. The condition can be improved and the DTCs eliminated when the crankcase pressure valve is changed to a lower operating pressure and the ECM software is updated to compensate for new crankcase pressure.

| 01134520314584 | 2023-01-03. Service bulletin. Under extreme driving conditions (such short-distance, stop-and-go driving), high crankcase pressure can cause the DTCs to appear. |
| 01125820314581 | 2023-01-03. Service bulletin. 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. |
