Bulletin Summary
CONDITION Isuzu Motors Limited has decided that a defect exists in certain 2022 model year Isuzu F-Series vehicles. Due to a software calibration error, the affected vehicles were built without engine exhaust braking functionality. Without engine braking, a driver may experience longer stopping distances than expected, increasing the risk of a crash. CORRECTION Isuzu dealers will have the Cummins Engine Control Module (ECM) reprogrammed with the correct calibration setting for the engine exhaust brake. This service will be performed 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.
