Bulletin Summary
This Preliminary information communicates concerns created by an aftermarket ECM calibration installed by fleet companies. The Fleet companies install aftermarket ECM calibrations to limit the vehicle speed to approximately 70 mph and reduce the over all power output. This calibration also reduces the engine idle speed and may induce a vibration at idle. If the vehicle needs to be returned to factory specifications, the ECM must be replaced and programmed.
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.
