TSB 25-2420

Some of the vehicles listed in the Model statement above built with minor feature code AAZNQ or AAZNS (gross vehicle weight rating ÝGVWR ̈ 9,900 lb. or 10,000 lb. pounds) may exhibit an incorrectly illuminated malfunction indicator lamp (MIL) with diagnostic trouble code (DTC) P20EE stored in the powertrain control module (PCM). This may be due to the calibration in the PCM. This condition does not affect vehicle drivability or durability. To confirm a vehicle is built with a certain minor feature code, review the build information by double-clicking the vehicle identification number (VIN) in the upper left corner in the Professional Technician System (PTS).
