MASC (Mitsubishi Active Stability Control) is a stability control that used in Mitsubishi models. It prevents skidding and improves the car's traction and manoeuvrability.
How MASC works
The MASC sets the actual driving path of the vehicle based on it based on wheel speed, yaw rate, and lateral and longitudinal acceleration. Sensors transmit data about the steering angle, brake fluid pressure and brake pedal position, so information about the driver's actions is transmitted.
If the vehicle's actual path does not correspond to the desired course, the system brakes individual wheels and reduces the torque of the engine . The ABS pump and valves, which can increase the pressure in the relevant braking circuit, are used to actuate the brakes. Engine torque is reduced by adjusting the throttle position and/or disabling the injectors.
Popular Mitsubishi Models with MASC
- Pajero V80, V90, Sport KS
- Outlander GG, GF
- Lancer VIII
- L200 MQ
Causes of defects
- Oxidized contacts of the ABS, yaw rate and lateral acceleration sensors
- Defective air mass meter
- Assembly of tires of different sizes
- Use of a space-saving spare wheel
- Defective steering angle sensor.
