Bulletin Summary
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.

About Technical Service Bulletins
A Technical Service Bulletin (TSB) is a document issued by a vehicle manufacturer to its dealers, describing a known issue with a specific vehicle or set of vehicles and the recommended procedure to fix it. Unlike recalls, TSBs are not mandatory and are typically only performed if an owner reports the related issue. However, TSBs can be an indicator of common problems with a vehicle.
