DTC C1222 POSSIBLE CAUSE DTC C1222 ABS wheel-speed sensor (slip monitor) system DETECTION CONDITION Difference between any vehicle wheel speeds exceeds specification when driving at a constant speed. ABS control operates for 60 s or more. POSSIBLE CAUSE 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
