Diagnosis Procedure
1.CHECKING CONNECTOR
  1. Disconnect 12V battery negative terminal.
  2. Check if there is open circuit or looseness in the parking brake actuator harness connector.
  3. Check if there is open circuit or looseness in the ABS actuator and electric unit (control unit) harness connector.
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).
  2. Check the continuity between the ABS actuator and electric unit (control unit) harness connector terminals.

5.CHECK MOTOR POWER SUPPLY CIRCUIT
  1. Disconnect 12V battery negative terminal.
  2. Check the 30 A fuse (No. 2).
  3. Check the continuity and short circuit between the ABS actuator and electric unit (control unit) harness connector terminal No. 30 and the 30 A fuse (No. 2).
Is the inspection result normal?
Perform trouble diagnosis for 12V battery power supply.
Repair / replace harness, connector or fuse.
 
6.CHECK ABS ACTUATOR AND ELECTRIC UNIT (CONTROL UNIT) GROUND CIRCUIT
Check the continuity between the ABS actuator and electric unit (control unit) harness connector and ground.

E12546GroundContinuity exists
Is the inspection result normal?
Repair / replace harness, connector or terminal.
 
7.CHECK TERMINAL
  1. Check that there is no damage on the parking brake actuator terminals, and check that the wiring harness connector is properly connected.
  2. Check if there is damage tn the terminal, or looseness in the ABS actuator and electric unit (control unit) harness connector.
Is the inspection result normal?
Repair / replace harness, connector or terminal.
 
8.PERFORM DIAGNOSTIC TROUBLE CODE
M.U.T.-IIISE
  1. Connect the parking brake actuator harness connector.
  2. Connect the ABS actuator and electric unit (control unit).
  3. Connect the battery negative terminal.
  4. Change the electric motor switch to ON.
  5. Apply and release the parking brake five times.
  6. Perform Diagnostic Trouble Code for “ABS".
Is DTC "C10B3-49" detected?
-1"Active DTC" is displayed.: Replace the ABS actuator and electric unit (control unit). Removal and Installation.
-2"Stored DTC" is displayed: INSPECTION END (Erase the memory of Diagnostic Trouble Code results.)
