INSPECTION PROCEDURE

NOTICE:
When replacing the ABS and TRACTION actuator assembly, perform zero point calibration (Click here).

1.INSPECT DLC3 TERMINAL VOLTAGE (TC TERMINAL VOLTAGE)


    C052361E66
  1. Turn the engine switch on (IG).

  1. Measure the voltage according to the value(s) in the table below.

    Voltage:
    Tester Connection
    Condition
    Specified Condition
    L16-13 (TC) - Body ground
    Engine switch on (IG)
    10 to 14 V

  1. Measure the resistance according to the value(s) in the table below.

    Resistance:
    Tester Connection
    Specified Condition
    L16-4 (CG) - Body ground
    Below 1 Ω



NG
Go to step 4
OK


2.CHECK HARNESS AND CONNECTOR (ECM TO DLC3)


    C110579E02
  1. Disconnect the ECM connector.

  1. Measure the resistance according to the value(s) in the table below.

    Resistance:
    Tester Connection
    Specified Condition
    L16-13 (TC) - A7-3 (TC)
    Below 1 Ω

  1. Measure the resistance according to the value(s) in the table below.

    Resistance:
    Tester Connection
    Specified Condition
    L16-13 (TC) - Body ground
    10 kΩ or higher



NG
REPAIR OR REPLACE HARNESS OR CONNECTOR (TC TERMINAL CIRCUIT)
OK


3.CHECK CAN COMMUNICATION SYSTEM
  1. Check if the CAN communication DTC is output (Click here).

    Result:

    Condition
    Proceed To
    DTC is not output
    A
    DTC is output
    B

    HINT:
    If troubleshooting has been carried out according to the problem symptoms table, refer back to the table and proceed to the next step before replacing the part (Click here).



B
REPAIR CAN COMMUNICATION SYSTEM
A

REPLACE ABS AND TRACTION ACTUATOR ASSEMBLY 

4.CHECK HARNESS AND CONNECTOR (ECM TO DLC3)


    C110579E02
  1. Disconnect the ECM connector.

  1. Measure the resistance according to the value(s) in the table below.

    Resistance:
    Tester Connection
    Specified Condition
    L16-13 (TC) - A7-3 (TC)
    Below 1 Ω

  1. Measure the resistance according to the value(s) in the table below.

    Resistance:
    Tester Connection
    Specified Condition
    L16-13 (TC) - Body ground
    10 kΩ or higher



NG
REPAIR OR REPLACE HARNESS OR CONNECTOR (TC CIRCUIT)
OK


5.CHECK HARNESS AND CONNECTOR (DLC3 TO BODY GROUND)


    C052361E67
  1. Measure the resistance according to the value(s) in the table below.

    Resistance:
    Tester Connection
    Specified Condition
    L16-4 (CG) - Body ground
    Below 1 Ω



NG
REPAIR OR REPLACE HARNESS OR CONNECTOR
OK


6.CHECK ECM (DLC3 (TC) INPUT)


    C052361E68
  1. Using the SST, connect terminals TC and CG of the DLC3.

  1. Check that the engine warning light is blinking.

    Result:
    Condition
    Proceed To
    Engine warning light is blinking
    A
    Engine warning light is not blinking
    B



B
REPAIR OR REPLACE HARNESS OR CONNECTOR (ECM (TC) CIRCUIT)
A


7.CHECK CAN COMMUNICATION SYSTEM
  1. Check if the CAN communication system DTC is output (Click here).

    Result:

    Condition
    Proceed To
    DTC is not output
    A
    DTC is output
    B

    HINT:
