An official CAA Japan notice concerns Passenger cars (Mitsubishi eK and others) - Repair. Defect in the engine (engine ECU). ■ Defective component (part name): Engine (engine ECU). ■ Noncompliant structure, equipment or performance and its cause: The generator control logic in the engine control unit (ECU) is inappropriate. When the battery charge level is low, driving immediately after a cold start or driving down a long slope may cause engine vacuum to decrease. This may result in insufficient vacuum supply to the brake booster and, in the worst case, increase the force required to operate the brake pedal and lengthen the braking stopping distance. Published 2020-04-17.
What to do now
(Recall) 4735 ■ Corrective measures: Rewrite the engine ECU control program to the corrective specification on all vehicles.
