Hazard

The 48V ground wiring located beneath the front passenger seat may have been improperly assembled during manufacturing, resulting in nuts not being tightened to the specified torque. This can cause loss of electrical continuity due to vibration during operation, illuminating warning lights and generating heat from increased electrical contact resistance, which in the worst case may lead to fire.

助手席の下にある48Vのアース配線において、製造時の組み付けが不適切なため、ナットが適切なトルクで締め付けられていないものがある。そのため、走行中の振動等により導通不良が発生し、警告灯が点灯すると共に増加した電気接触抵抗により発熱して、最悪の場合、火災に至るおそれがある。

Remedy

Inspect the nut tightening torque on all vehicles. If looseness or heat damage is found, replace the damaged components with new parts and secure them with the proper tightening torque.
