Hazard
In the engine ignition coils, due to inadequate maintenance of manufacturing equipment, the secondary coil wiring is excessively long, causing short circuits within the circuit that prevent high voltage generation. This results in misfiring of affected cylinders, leading to reduced engine output and illumination of the engine warning light (MIL). In worst-case scenarios, exhaust emissions may exceed regulatory limits.

エンジンの点火コイルにおいて、製造設備の保守が不適切なため、２次コイルの配線が長く、回路内で短絡が発生して高電圧が生成できなくなり、影響を受けたシリンダが失火することがある。そのため、エンジンの出力が低下するとともにエンジン警告灯（ＭＩＬ）が点灯し、最悪の場合、排出ガスが基準値を超えるおそれがある。
Remedy
Replace the ignition coil with a serviceable unit on all vehicles.
