ANTI-LOCK BRAKE SYSTEM, Diagnostic DTC:C0226/21, C0236/22, C0246/23

DTC Code DTC Name
C0226/21 SFR Solenoid Circuit
C0236/22 SFL Solenoid Circuit
C0246/23 SRR Solenoid Circuit

DESCRIPTION

ABS solenoids turn on when receiving signals from the ECU. They control braking force by adjusting the pressure applied to the wheel cylinders.

INSPECTION PROCEDURE

PROCEDURE


  1. RECONFIRM DTC

    Tech Tips

    These codes are output when a problem is detected in the brake actuator assembly.

    As the solenoid circuit is built into the brake actuator assembly, solenoid circuit inspection and solenoid unit inspection cannot be performed.

    Be sure to check if the DTC is output before replacing the brake actuator assembly.


    1. Clear the DTCs.

    2. Turn the ignition switch ON and check that the ABS warning light illuminates for approximately 3 seconds.

    3. Check for DTCs.

      Result
      Result Proceed to
      DTC is not output A
      DTC is output B

    B

    REPLACE BRAKE ACTUATOR ASSEMBLY

    A

  2. PERFORM ACTIVE TEST BY INTELLIGENT TESTER (ABS SOLENOID)


    1. Using the intelligent tester's Active Test, generate a control command and then check that the ABS solenoid operates.

      Skid control ECU
