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.

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.
