DTC C1222 [DYNAMIC STABILITY CONTROL (DSC)] Mazda MX-5 NC рестайлинг

Note. DTC C1222 will be detected when a malfunctioning ABS wheel-speed sensor cannot be specified.

DTC C1222 DETECTION CONDITION AND POSSIBLE CAUSE DTC C1222 ABS wheel-speed sensor (slip monitor) system DETECTION CONDITION Condition 1 ABS control for two wheels or more is continued for 60 s (If accelerator pedal is ON and brake switch is OFF and vehicle speed is more than 50 km/h {31 mph} , it is detected when 10 s has elapsed). Condition 2 While the vehicle is driven at a speed of 20 km/h {13 mph} or more, difference in each wheel speed is continuously not within the specification. Condition 3 There is difference between yaw rate value calculated based on the ABS wheel-speed sensor and yaw rate value calculated based on the steering angle sensor (abnormal cornering direction is detected). POSSIBLE CAUSE Tire type or size is different between the front and rear wheels. ABS wheel-speed sensor malfunction (low output, metal shavings on sensor) ABS sensor rotor malfunction (chipping of sensor rotor teeth) Poor installation of ABS wheel-speed sensor and/or sensor rotor (If the sensor rotor is installed at an angle, it may cause output of abnormal wave pattern at high speeds) Excessive clearance between the ABS wheel-speed sensor and sensor rotor
