Hazard
In the secondary air pump of the exhaust emission control system, improper contact pressure within the relay controlling the pump causes arc discharge when contacts close, leading to contact welding and continuous current flow. This causes the pump motor to run continuously, raising internal pressure in the secondary air piping and illuminating a warning light. Continued operation causes the pump to overheat, melting resin components and generating abnormal odors and smoke, with potential risk of fire in severe cases.

排出ガス発散防止装置の２次エアポンプにおいて、当該ポンプを制御するリレー内の接点の押付け力が不適切なため、接点オン時にアーク放電が発生し、接点が溶着され電流が流れ続けることがある。そのため、当該ポンプのポンプモーターが常時回転となり、２次エア配管の内圧が上昇し警告灯が点灯、そのまま使用を続けると、ポンプが高温となり樹脂部品が溶損し異臭や煙が発生、最悪の場合、火災に至るおそれがある。
Remedy
Replace the secondary air pump relay with a corrective part on all vehicles.
