Service bulletin 167-R2211-1

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

Certain 2017 ~ 2020 model year Hino Conventional vehicles were manufactured with a modified jumper harness between the Transmission Control Module (TCM) and vehicle chassis. The modified jumper harness may allow for potential water intrusion of the modified jumper harness. Water intrusion may cause illumination of the check transmission light on the dashboard. If the illuminated check transmission light is ignored, the transmission may go into fail-safe (or “limp” mode as it is also called) to protect the transmission from internal damage that could be caused by the fault. While in fail-safe (or limp mode) the transmission will be locked in either 3rd. or 4th. gear. This procedure will provide instruction for replacement of the transmission jumper harness.
