Bulletin 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 âlimpâ 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.
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.
