Defect
The auxiliary power module control software is incorrect. During the transition from deceleration idling stop back to acceleration, the software incorrectly identifies the large current flowing through the motor-generator as excessive and activates a protection mode that cuts off charging to the lead-acid battery. This causes a warning lamp to flash. Continued operation in this condition discharges the lead-acid battery and, in the worst case, may cause engine stall or prevent the engine from starting.
Corrective action
Reprogram the auxiliary power module control software, or replace the auxiliary power module with a corrected part.

状況
補助電源モジュールの制御プログラムが不適切なため、減速時アイドリングストップ状態から再加速に切り替わる過渡期に、スタータ機能付発電機に流れる大電流を過大と判断し、鉛バッテリへの充電回路を遮断したままとする保護制御に入ることがある。このため、表示灯が点滅し、そのままの状態で使用を続けると、鉛バッテリが放電し、最悪の場合、エンストやエンジン始動不能に至るおそれがある。
改善措置
補助電源モジュールの制御プログラムを書き換える、または、補助電源モジュールを対策品に交換する。
