Service bulletin ONLJ8F20220830

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

Owner notification - Our records indicate that a Emissions Recall has not been completed on this vehicle. When the powertrain control module (PCM) detects a malfunction in one of the odd number transmission gears, it will set one of four diagnostic trouble codes (DTCs). Due to inappropriate calibration of the PCM, the On Board Diagnostic (OBD) system cannot properly clear the transmission permanent DTC as required.
