Service bulletin K0B Modified Veh

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

Tundra and Tacoma vehicles covered by K0B must be inspected for non-Toyota-approved modifications to determine if the remedy can be performed. Some vehicles with non-Toyota-approved modifications may have the remedy performed, depending on the type of modification. This Job Aid is designed to assist the ASM with the inspection while the vehicle is on the service drive.
