# Service bulletin CB23\-N\-003

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

## NHTSA's 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 “next recommended service” date. Dealers will reprogram the MMU to correct the mileage accumulation. This service will be provided free of charge.
