Hazard
In large trucks, the fixing method for the urea water piping with electric heating and the coolant piping is inadequate. During operation, vibration causes both pipings to contact each other, which can break the electric heating line. This causes the engine warning light (MIL) to illuminate. If the vehicle continues to be used in this condition, urea water may freeze in low temperatures and NOx in exhaust gas may increase.

大型トラックにおいて、電熱線付き尿素水配管と冷却水配管の固定方法が不適切なため、走行中の振動で両配管が接触し電熱線が断線することがある。そのため、エンジン警告灯（ＭＩＬ）が点灯し、そのまま使用すると低温時に尿素水が凍結し排出ガス中のＮＯｘが増加するおそれがある。
Remedy
For all vehicles, replace the piping fixing bands with improved parts and add additional bands. Also inspect the piping and repair or replace it with new parts if damage is found.
