Diagnostic Test

  1. CHECK THE TEMPERATURE OF CONTROL MODULE

    G-20With CONSULT 

    1. Start the engine.
      CAUTION:

      Never drive the vehicle.

    2. On the CONSULT screen, select "EPS/DAST 3">>"DATA MONITOR">>"C/M TEMPERATURE".
    3. Wait with the ignition switch OFF until the data monitor indication becomes 140°C (284°F) or less.

    Does the temperature drop to 140°C (284°F) or less?

    YES 

    GO TO STEP 2  .

    NO 

    GO TO STEP 3  .

  2. PERFORM SELF-DIAGNOSIS

    G-20With CONSULT 

    1. Turn the ignition switch ON.
    2. Erase self-diagnosis for "EPS/DAST 3".
    3. Turn the ignition switch OFF and wait for at least 10 seconds.
    4. Start the engine.
      CAUTION:

      Never drive the vehicle.

    5. Perform self-diagnosis for "EPS/DAST 3".

    Is DTC "C13E6 - 00" detected?

    YES 

    Replace steering force control module. Refer to REMOVAL AND INSTALLATION .

    NO 

    The rise of steering force motor internal temperature caused the protection function to operate. This is not a system malfunction. INSPECTION END

  3. CHECK TEMPERATURE SENSOR POWER SUPPLY (1)

    1. Turn the ignition switch OFF.
    2. Disconnect force motor angle sensor harness connector.
    3. Turn the ignition switch ON.
    4. Check the voltage between force motor angle sensor harness connector pin terminals.
      Force motor angle sensor Voltage (Approx.)
      Connector Terminal
      + -
      M73 3 7 5 V

    Is the inspection result normal?

    YES 

    GO TO STEP 9  .

    NO 

    GO TO STEP 4  .

  4. CHECK TEMPERATURE SENSOR POWER SUPPLY (2)

    Check the voltage between force motor angle sensor harness connector pin terminals.

    Force motor angle sensor - Voltage (Approx.)
    Connector Terminal
    + -
    M73 3 Ground 5 V

    Is the inspection result normal?

    YES 

    GO TO STEP 5  .

    NO 

    GO TO STEP 7  .

  5. CHECK TEMPERATURE SENSOR GROUND CIRCUIT

    1. Turn the ignition switch OFF.
    2. Disconnect steering force control module harness connector.
    3. Check the continuity between steering force control module harness connector and force motor angle sensor harness connector.
      Steering force control module Force motor angle sensor Continuity
      Connector Terminal Connector Terminal
      M71 29 M73 7 Existed

    Is the inspection result normal?

    YES 

    GO TO STEP 6  .

    NO 

    Repair open circuit or short to ground or short to power in harness or connectors.

  6. CHECK CONTROL MODULE GROUND CIRCUIT

    Check the continuity between steering force control module harness connector and ground.

    Steering force control module - Continuity
    Connector Terminal
    M71 30 Ground Existed
    M72 33

    Is the inspection result normal?

    YES 

    GO TO STEP 10  .

    NO 

    Repair open circuit or short to ground or short to power in harness or connectors.

  7. CHECK TEMPERATURE SENSOR POWER SUPPLY CIRCUIT

    1. Turn the ignition switch OFF.
    2. Disconnect steering force control module harness connector.
    3. Check the continuity between steering force control module harness connector and force motor angle sensor harness connector.
      Steering force control module Force motor angle sensor Continuity
      Connector Terminal Connector Terminal
      M71 31 M73 3 Existed
    4. Check the continuity between steering force control module harness connector and ground.
      Steering force control module - Continuity
      Connector Terminal
      M71 31 Ground Not existed

    Is the inspection result normal?

    YES 

    GO TO STEP 8  .

    NO 

    Repair open circuit or short to ground or short to power in harness or connectors.

  8. CHECK CONTROL MODULE POWER SUPPLY CIRCUIT

    Check the power supply circuit for steering force control module. Refer to DIAGNOSIS PROCEDURE .

    Is the inspection result normal?

    YES 

    GO TO STEP 10  .

    NO 

    Repair or replace error - detected part.

  9. CHECK TEMPERATURE SENSOR

    Check the force motor temperature sensor. Refer to COMPONENT INSPECTION .

    Is the inspection result normal?

    YES 

    GO TO STEP 10  .

    NO 

    Force motor temperature sensor is malfunction. Replace steering column assembly. Refer to REMOVAL AND INSTALLATION .

  10. CHECK INTERMITTENT INCIDENT

    1. Check enlarged contact spring of terminal. Refer to HOW TO CHECK TERMINAL .
    2. Perform intermittent incident while turning steering wheel. Refer to INTERMITTENT INCIDENT .

    Is the inspection result normal?

    YES 

    Replace steering force control module. Refer to REMOVAL AND INSTALLATION .

    NO 

    Repair or replace error - detected part.
