Bulletin Summary
Customer Satisfaction Program - Certain vehicles equipped with tire size 255/70R22.5 may have a calibration error where the vehicles were built with an incorrect tire size value. As a results, the speedometer will show a vehicle speed higher than the actual vehicle speed while driving and the odometer will accumulate miles faster (approximately 14% faster) than the âactualâ or âTrueâ vehicle miles. Additionally, mileage data collected and stored in the Mimamori Unit (MMU), will be incorrect. Dealer will have the Cummins Engine Control Module (ECM) reprogrammed with the correct tire size value and reprogram the MMU.
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.
