Filing in context
The Computer (engine) is the most frequently cited component category in this archive, appearing in 16 of its 4,890 filings. This filing is one of 31 Hino notifications from 2016 in this archive. For scale, 1,772 of the 4,890 filings in this archive report a larger number of affected vehicles; the vehicles involved here were manufactured over a span of about 4 years and 5 months.
Defect
On heavy-duty trucks, the engine control program is incorrect. When manual regeneration of the DPR (exhaust gas purification device) is interrupted frequently, fuel from post-injection migrates into the EGR cooler, generating carbon deposits that adhere to the intake valves. Extended parking after this condition increases the viscosity of the carbon deposits. This causes the intake valves to bind. In the worst case, a valve may fracture, producing abnormal noise and damaging the engine.
Corrective action
On all vehicles, reprogram the engine control software. If abnormal noise from the intake valves is detected during the post-reprogramming inspection, replace the complete cylinder head assembly.
Affected models & chassis ranges
This filing lists 121 type code(s). A vehicle is affected if its chassis number falls within one of the ranges below.

Original Japanese (MLIT source text)
Show the original Japanese filing text
状況
大型トラックにおいて、エンジン制御プログラムが不適切なため、ＤＰＲ（排出ガス浄化装置）の手動再生を頻繁に中断した場合、ポスト噴射による燃料がＥＧＲクーラに廻り込み、カーボンデポジットが生成されて吸気バルブに付着し、そのままの状態で長時間駐車するとカーボンデポジットの粘度が増加することがある。そのため、吸気バルブが摺動不良となり、最悪の場合、バルブが折損し、異音が発生するとともにエンジンが破損するおそれがある。
改善措置
全車両、エンジン制御プログラムを書き換える。また、書き換え作業後の点検で吸気バルブから異音がしている場合は、シリンダヘッド一式を交換する。
