Diagnosis Procedure
1.CHECK CONNECTOR
  1. Disconnect 12V battery negative terminal.
  2. Check the parking brake actuator (LH) harness connector for disconnection or looseness.
  3. Check the ABS actuator and electric unit (control unit) harness connector for disconnection or looseness.
Is the inspection result normal?
.
Repair / replace harness or connector. .
 
2.CHECK PARKING BRAKE ACTUATOR CIRCUIT (1)
  1. Disconnect the ABS actuator and electric unit (control unit) harness connector.
  2. Check the continuity between ABS actuator and electric unit (control unit) harness connector terminals.

8.PERFORM SELF-DIAGNOSIS
With M.U.T.-III SE
  1. Connect the parking brake actuator (LH) harness connector.
  2. Connect the ABS actuator and electric unit (control unit) harness connector.
  3. Connect 12V battery negative terminal.
  4. Ignition switch ON.
  5. Apply and release the parking brake five times.
  6. Perform self-diagnosis for “ABS”.
Is DTC “C10B1-01” detected?
-1"CRNT" is displayed: Replace the ABS actuator and electric unit (control unit). Refer to Removal and Installation.
-2"PAST" is displayed: INSPECTION END (Erase the memory of self-diagnosis results.)
