Overview
| MLIT filing number | 1146221 |
|---|---|
| Type | Statutory Recall (government-mandated recall) |
| Date filed | December 12, 2019 |
| Manufacturer(s) | Honda |
| Component | Parking brake (general) |
| Production period | July 2019 — August 30, 2019 |
| Vehicles affected | 9,437 units |
Defect
In the electric parking brake system, the crimp terminals at the motor wiring connections inside the actuator are insufficiently crimped, or the motor commutator and brushes are improperly manufactured. When driving vibration temporarily increases contact resistance within the motor, the motor circuit disconnection detection signal becomes erratic, causing the VSA system to detect an anomaly and register a fault. As a result, warning lamps and warning messages illuminate, and the parking brake may fail to apply or may become impossible to release.
Corrective action
On all vehicles, replace the left and right electric parking brake assemblies with corrected parts and reprogram the VSA modulator motor circuit disconnection detection software.

状況
電動パーキングブレーキにおいて、アクチュエータ内のモータ配線接続部の圧着端子の加締めが不十分、または、モータのコンミテータ及びブラシの製造が不適切なため、走行振動でモータ内の接触抵抗が一時的に増加するとモータ回路断線検知信号が乱れてＶＳＡが異常を検知し、故障と判定することがある。そのため、警告灯、警告表示が点灯して、駐車ブレーキが作動しなくなる、または、駐車ブレーキが解除できなくなるおそれがある。
改善措置
全車両、左右電動パーキングブレーキアッセンブリを対策品と交換するとともに、ＶＳＡモジュレータのモータ回路断線検知プログラムを書き換える。
