Inspection Procedure

NOTE: When replacing the skid control ECU or brake actuator assembly, perform initialization of linear solenoid valve and calibration (see INITIALIZATION  ).
  1. CHECK HARNESS AND CONNECTOR (SKID CONTROL ECU TO BRAKE ACTUATOR ASSEMBLY) 
    1. Disconnect the skid control ECU and brake actuator assembly connector.
    2. Measure the resistance according to the value (s) in the table below.

      Resistance 

      RESISTANCE REFERENCE CHART

      Tester Connection Specified Condition
      A13-9 (PCK1) - A16-37 (PCK1) Below 1 Ω
      A13-26 (PAC1) - A16-46 (PAC1) Below 1 Ω
      A13-27 (VCM) - A16-3S (VCM) Below 1 Ω
      A13-43 (E) - A16-45 (E) Below 1 Ω
    3. Measure the resistance according to the value (s) in the table below.

      Tester Connection Specified Condition
      A13-9 (PCK1) - Body ground 10 kΩ or higher
      A13-26 (PAC1) - Body ground 10 kΩ or higher
      A13-27 (VCM) - Body ground 10 kΩ or higher
      A13-43 (E) - Body ground 10 kΩ or higher

    NG : REPAIR OR REPLACE HARNESS OR CONNECTOR

    OK : Go to Next Step 

  2. RECONFIRM DTC 
    1. Clear the DTC (see DTC CHECK/CLEAR  ).
    2. Turn the engine switch on (IG).
    3. Check if the same DTC is recorded (see DTC CHECK/CLEAR  ).

      HINT:

      Reinstall the sensors, connectors, etc. and restore the vehicle to its prior condition before rechecking for DTCs.

      Result 

      RESULT REFERENCE

      Display (DTC Output) Proceed To
      DTC (C1365/54) is output A
      DTC (C1365/54) is not output B

    B : END 

    A : Go to Next Step 

  3. CHECK FREEZE FRAME DATA 
    1. Check the information code from the Freeze Frame Data memorized when the DTC (C1365/54) is stored (see FREEZE FRAME DATA  ).

      Result 

      RESULT REFERENCE

      Condition Proceed To
      Sensor power supply voltage trouble codes (211) are output A
      Sensor output value trouble codes (212,214 and 215) are output B

    B : REPLACE BRAKE ACTUATOR ASSEMBLY 

    A : REPLACE SKID CONTROL ECU
