The DTC is output when tire deformation or a difference in tire size is detected.
OK:
The diameter of all 4 tires and air pressure are the same.
Result:
C -- REPLACE TIRES SO THAT ALL FOUR TIRES ARE SAME SIZE
B -- CHECK HARNESS AND CONNECTOR (SKID CONTROL SENSOR WIRE)
A -- Continue to next step.
2. CHECK EACH SPEED SENSOR TIP
(a) Remove the front speed sensor or the rear speed sensor See: Brakes and Traction Control/Antilock Brakes / Traction Control
Systems/Wheel Speed Sensor/Service and Repair/Front Speed Sensor/Removal for front, or See: Brakes and Traction
Control/Antilock Brakes / Traction Control Systems/Wheel Speed Sensor/Service and Repair/Rear Speed Sensor/Removal for rear).
(b) Check the speed sensor tip.
OK:
No scratches, oil, or foreign matter on the sensor tip.
NOTICE:
Check the speed sensor signal after cleaning or replacement See: Brakes and Traction Control/Antilock Brakes / Traction
Control Systems/Testing and Inspection/Initial Inspection and Diagnostic Overview/Test Mode Procedure.
NG -- CLEAN OR REPLACE EACH SPEED SENSOR
OK -- Continue to next step.
3. CHECK EACH SPEED SENSOR ROTOR
(a) Remove the front speed sensor rotor or the rear speed sensor rotor See: Transmission and Drivetrain/Drive Axles, Bearings and
Joints/Axle Shaft Assembly/Service and Repair/Front Drive Shaft Assembly/Removal for front, or See: Maintenance/Wheels and
Tires/Wheel Hub/Service and Repair/Rear Axle Hub/Removal for rear).
(b) Check the speed sensor rotor.
OK:
