An official CAA Japan notice concerns Passenger cars (Mitsubishi Outlander PHEV and others) - Repair. Braking system (brake hydraulic unit) defect. ■Defective part (component name): Braking system (brake hydraulic unit). ■Condition and cause of the structure, equipment, or performance deemed noncompliant with standards: Because the control program in the brake hydraulic unit ECU is inappropriate, electrical noise may occur when control of the hydraulic unit pump motor switches, interrupting ECU control. As a result, ASC※1 and ABS※2 functions may be temporarily interrupted, potentially impairing vehicle stability during that time. In vehicles equipped with ACC※3, FCM※4, BAH※5, HSA※6, or S-AWC※7, these functions may also stop while operating. ※1 ASC: A system that prevents skidding. ※2 ABS: A system that prevents the tires from locking during braking. ※3 ACC: A system that maintains a set vehicle speed and slows the vehicle to maintain distance when approaching a vehicle ahead. ※4 FCM: A system that automatically applies the brakes to reduce collision damage. ※5 BAH: A function that maintains braking force and keeps the vehicle stationary even after the brake pedal is released following a stop. ※6 HSA: A function that reduces backward rolling when starting on a slope. ※7 S-AWC: An integrated vehicle dynamics control system. Published 2018-09-13.
What to do now
(Recall) 4321. ■Corrective measures: Rewrite the brake hydraulic unit ECU control program on all vehicles to the corrected specification.
