- 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.
