If a normal code is displayed during the DTC check but the problem still occurs, check the circuits for each problem symptom in the order given in the table below and proceed to the relevant troubleshooting page.

NOTE:
  • When replacing the skid control ECU, sensors or etc., turn the ignition switch off. 
  • When replacing yaw rate sensor and/or the brake actuator assy, make sure to perform yaw rate sensor zero point calibration (See  CALIBRATION   ).
