DTC C0226/21 SFR Solenoid Circuit

DTC C0236/22 SFL Solenoid Circuit

DTC C0246/23 SRR Solenoid Circuit


DESCRIPTION

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

DTC No.

INSPECTION PROCEDURE

1.RECONFIRM DTC
HINT:
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.

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

  1. Check for DTCs.
