VC Output Circuit [10/2013 - ]: Procedure

  1. CHECK MIL 
    1. Check that the Malfunction Indicator Lamp (MIL) illuminates when turning the power switch on (IG).

      OK

      MIL lights up.

    NG → See step   2 

    OK → See step   14 

  2. CHECK CONNECTION BETWEEN TECHSTREAM AND ECM 
    1. Connect the Techstream to the DLC3.
    2. Turn the power switch on (IG).
    3. Turn the Techstream on.
    4. Check the communication between the Techstream and ECM.

      Result

      Result Proceed to
      Communication is not possible A
      Communication is possible B

    B → See step   12 

    A: Go to next step 

  3. CHECK MIL (THROTTLE POSITION SENSOR) 
    1. Disconnect the throttle position sensor connector.
    2. Turn the power switch on (IG).
    3. Check the MIL.

      Result

      Result Proceed to
      MIL does not illuminate A
      MIL illuminates B

      HINT: 

      Perform "Inspection After Repair" after replacing the throttle body assembly. Refer to INITIALIZATION [10/2013 - ] .

    B → See step   13 

    A: Go to next step 

  4. CHECK MIL (CAMSHAFT POSITION SENSOR) 
    1. Disconnect the camshaft position sensor connector.
    2. Turn the power switch on (IG).
    3. Check the MIL.

      Result

      Result Proceed to
      MIL does not illuminate A
      MIL illuminates B

    B → See step   15 

    A: Go to next step 

  5. CHECK MIL (MANIFOLD ABSOLUTE PRESSURE SENSOR) 
    1. Disconnect the manifold absolute pressure sensor connector.
    2. Turn the power switch on (IG).
    3. Check the MIL.

      Result

      Result Proceed to
      MIL does not illuminate A
      MIL illuminates B

    B → See step   17 

    A: Go to next step 

  6. CHECK MIL (CANISTER PUMP MODULE) 
    1. Disconnect the canister pump module connector.
    2. Turn the power switch on (IG).
    3. Check the MIL.

      Result

      Result Proceed to
      MIL does not illuminate A
      MIL illuminates B

    B → See step   16 

    A: Go to next step 

  7. CHECK HARNESS AND CONNECTOR (THROTTLE POSITION SENSOR - ECM) 
    1. Disconnect the throttle position sensor connector.
    2. Disconnect the ECM connector.
    3. Measure the resistance according to the value(s) in the table below.

      Standard Resistance

      Tester Connection Condition Specified Condition
      D28-88 (VCTA) or D4-5 (VC) - Body ground Always 10 kΩ or higher

    NG → REPAIR OR REPLACE HARNESS OR CONNECTOR 

    OK: Go to next step 

  8. CHECK HARNESS AND CONNECTOR (CAMSHAFT POSITION SENSOR - ECM) 
    1. Disconnect the camshaft position sensor connector.
    2. Disconnect the ECM connector.
    3. Measure the resistance according to the value(s) in the table below.

      Standard Resistance

      Tester Connection Condition Specified Condition
      D18-3 (VC) or D28-99 (VCV1) - Body ground Always 10 kΩ or higher

    NG → REPAIR OR REPLACE HARNESS OR CONNECTOR 

    OK: Go to next step 

  9. CHECK HARNESS AND CONNECTOR (MANIFOLD ABSOLUTE PRESSURE SENSOR - ECM) 
    1. Disconnect the manifold absolute pressure sensor connector.
    2. Disconnect the ECM connector.
    3. Measure the resistance according to the value(s) in the table below.

      Standard Resistance

      Tester Connection Condition Specified Condition
      D3-3 (VC) or D28-72 (VCPM) - Body ground Always 10 kΩ or higher

    NG → REPAIR OR REPLACE HARNESS OR CONNECTOR 

    OK: Go to next step 

  10. CHECK HARNESS AND CONNECTOR (CANISTER PUMP MODULE - ECM) 
    1. Disconnect the canister pump module connector.
    2. Disconnect the ECM connector.
    3. Measure the resistance according to the value(s) in the table below.

      Standard Resistance

      Tester Connection Condition Specified Condition
      S16-6 (VCC) or D28-113 (VCPP) - Body ground Always 10 kΩ or higher

    NG → REPAIR OR REPLACE HARNESS OR CONNECTOR 

    OK → See step   11
