Overview

MLIT filing number1134421
TypeStatutory Recall (government-mandated recall)
Date filedOctober 2, 2014
Manufacturer(s)Honda
ComponentEngine Control Computer
Production periodDecember 23, 2013 — August 18, 2014
Vehicles affected115,443 units

Defect

The engine control unit (ECU) program is incorrect, causing the data processing routines for the starter signal, intake air flow sensor, and related inputs to be overwritten with incorrect code immediately before engine shutdown. As a result, the ECU cannot perform normal control and the engine may fail to restart. On vehicles equipped with an idling stop system, the starter motor may engage intermittently without restarting the engine, causing damage to the starter motor. Additionally, after an idling stop system restart, the engine may run roughly, stall, and become unable to restart.

Corrective action

On all vehicles, reprogram the engine control unit with the corrected software. Inspect the starter motor and replace it with a new unit if damage is found.

状況

エンジン制御コンピュータ(ECU)のプログラムが不適切なため、エンジン停止直前にスタータ信号や吸気空気量センサ等のデータ処理プログラムを誤ったプログラムに書き換えてしまうことがある。そのため、ECUによる正常な制御が行われず、エンジンが再始動しないおそれがある。また、アイドリングストップシステム装着車においては、エンジンの再始動時に、スタータモータが断続的に回転して再始動せず、スタータモータが損傷する場合や、アイドリングストップシステムによるエンジン始動後にエンジン不調となり、エンジンが停止し再始動できなくなるおそれがある。

改善措置

全車両、エンジン制御コンピュータを対策プログラムに書き換えるとともに、スタータモータを点検し、損傷のあるものは新品と交換する。
