Inspection Procedure

NOTE: When replacing the master cylinder solenoid, perform zero point calibration (See CALIBRATION  ).
  1. INSPECT DLC3 (DLC3 (TC) - DLC3 (CG)) 
    1. Turn the ignition switch to ON.
    2. Measure the voltage according to the value(s) in the table below.

      Standard voltage 

      VOLTAGE REFERENCE

      Tester Connection Condition Specified Condition
      D1-13 (TC) - D1-4 (C6) Ignition switch ON 10 to 14 V

      NG: Go to step  4

      OK: Go to next step 

  2. CHECK DTC (FOR CAN COMMUNICATION SYSTEM) 
    1. Check for CAN communication system DTC.

      Result 

      DTC RESULT REFERENCE

      Result Proceed to
      DTC is not output A
      DTC is output B

      B: REPAIR CAN COMMUNICATION SYSTEM 

      A: Go to next step 

  3. CHECK ECM (DLC3 (TC) INPUT) 
    1. Using SST, connect terminal TC and CG of the DLC3.

      SST 09843-18040 

    2. Check if the malfunction indicator lamp is blinking.

      OK: 

      Malfunction indicator lamp is blinking. 

      NG: REPLACE ECM

      OK: REPLACE MASTER CYLINDER SOLENOID  (See DISASSEMBLY )

  4. CHECK HARNESS AND CONNECTOR (ECM - DLC3 (TC)) 
    1. Turn the ignition switch off.

    2. Disconnect the ECM connector.
    3. Measure the resistance according to the value(s) in the table below.

      Standard resistance 

      TESTER CONNECTION CONDITION CHART

      Tester Connection Condition Specified Condition
      E8-23 (TC) - D1-13 (TC) Always Below 1 Ω

      NG: REPAIR OR REPLACE HARNESS OR CONNECTOR 

      OK: Go to next step 

  5. CHECK HARNESS AND CONNECTOR (DLC3 (CG) - BODY GROUND) 
    1. Measure the resistance according to the value(s) in the table below.

      Standard resistance 

      TESTER CONNECTION CONDITION CHART

      Tester Connection Condition Specified Condition
      D1-4 (CG) - Body ground Always Below 1 Ω

      NG: REPAIR OR REPLACE HARNESS OR CONNECTOR

      OK: Go to next step 

  6. CHECK ECM (DLC3 (TC) INPUT) 
    1. Using SST, connect terminals TC and CG of the DLC3.

      SST 09843-18040 

    2. Check if the malfunction indicator lamp is blinking.

      Result 

      DTC RESULT REFERENCE

      Result Proceed to
      Malfunction Indicator lamp Is blinking A
      Malfunction indicator lamp Is not blinking B

      B: REPLACE ECM

      A: Go to next step 

  7. CHECK DTC (FOR CAN COMMUNICATION SYSTEM) 
    1. Check for CAN communication system DTC.

      Result 

      DTC RESULT REFERENCE

      Result Proceed to
      DTC is not output A
      DTC Is output B

      B: REPAIR CAN COMMUNICATION SYSTEM 

      A: REPLACE MASTER CYLINDER SOLENOID  (See DISASSEMBLY )
