Bulletin Summary
CUSTOMER SATISFACTION CAMPAIGN: In certain 2023 model year Isuzu F-Series trucks the Mimamori Control module (MMU) was not programmed with the correct tire size value. This error does not affect the drivability or performance of the affected vehicles. However, should Isuzu collect data from the MMU, this error will cause the accumulated mileage value shown in the captured data to be incorrect. As a result, the Isuzu Vehicle Health Report will incorrectly calculate mileage-based information such as the ânext recommended serviceâ date. Dealers will reprogram the MMU to correct the mileage accumulation. This service will be provided free of charge.
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.
