MIL Circuit [05/2013 - 01/2014]: Procedure

  1. CHECK THAT MIL IS ILLUMINATED 
    1. Perform troubleshooting in accordance with the table below.
      RESULT

      Result Proceed to
      MIL remains on A
      MIL does not illuminate B

    B → See step   5 

    A: Go to next step 

  2. CHECK WHETHER MIL TURNS OFF 
    1. Connect the Techstream to the DLC3.
    2. Turn the ignition switch to ON.
    3. Turn the Techstream on.
    4. Enter the following menus: Powertrain / Engine / Trouble Codes.
    5. Check if any DTCs have been stored. Note down any DTCs.
    6. Clear the DTCs. Refer to DTC CHECK / CLEAR [05/2013 - 01/2014] .
    7. Check if the MIL goes off.

      OK

      MIL goes off.

    NG → See step   3 

    OK → See step   8 

  3. CHECK HARNESS AND CONNECTOR (CHECK FOR SHORT IN WIRE HARNESS) 
    1. Disconnect the ECM connector.
    2. Turn the ignition switch to ON.
    3. Check that the MIL is not illuminated.

      OK

      MIL is not illuminated.

    NG → See step   4 

    OK → See step   9 

  4. CHECK HARNESS AND CONNECTOR (COMBINATION METER - ECM) 
    1. Disconnect the ECM connector.
    2. Disconnect the combination meter connector.
    3. Measure the resistance according to the value(s) in the table below.

      Standard Resistance

      Tester Connection Condition Specified Condition
      A35-36 (W) or C50-20 (CHK) - Body ground Always 10 kΩ or higher

    NG → REPAIR OR REPLACE HARNESS OR CONNECTOR 

    OK → See step   10 

  5. CHECK THAT MIL IS ILLUMINATED 
    1. Check if the MIL is illuminated when the ignition switch is turned to ON.

      OK

      MIL is illuminated.

    NG → See step   6 

    OK → END 

  6. CHECK THAT ENGINE STARTS 
    1. Turn the ignition switch to ON.
    2. Start the engine.
      RESULT

      Result Proceed to
      Engine starts A
      Engine does not start* B

      HINT: 

      *: The Techstream cannot communicate with the ECM.

    B → See step   12 

    A: Go to next step 

  7. CHECK HARNESS AND CONNECTOR (COMBINATION METER - ECM) 
    1. Disconnect the ECM connector.
    2. Disconnect the combination meter connector.
    3. Measure the resistance according to the value(s) in the table below.

      Standard Resistance

      Tester Connection Condition Specified Condition
      A35-36 (W) - C50-20 (CHK) Always Below 1 Ω

    NG → REPAIR OR REPLACE HARNESS OR CONNECTOR 

    OK → See step   11 

  8. REPAIR CIRCUITS INDICATED BY OUTPUT DTCS. Refer to  DIAGNOSTIC TROUBLE CODE CHART [05/2013 - 01/2014] 
  9. REPLACE ECM. Refer to  REMOVAL [05/2013 - 01/2014] 
  10. REPLACE COMBINATION METER ASSEMBLY. Refer to  REMOVAL [05/2013 - 01/2014] 
  11. REPLACE COMBINATION METER ASSEMBLY. Refer to  REMOVAL [05/2013 - 01/2014] 
  12. GO TO VC OUTPUT CIRCUIT. Refer to  VC Output Circuit
