      OK

      No DTCs are output.

      Result

      Proceed to
      OK
      NG

    Result: 

    NG 

    GO TO CAN COMMUNICATION SYSTEM. Refer to  HOW TO PROCEED WITH TROUBLESHOOTING [10/2014 - 09/2017]  , or refer to  HOW TO PROCEED WITH TROUBLESHOOTING [09/2017 - 05/2019]  , or refer to  HOW TO PROCEED WITH TROUBLESHOOTING [05/2019 - ] 

    Result: 

    OK 

    See step  2

  2. CHECK FOR DTC (SFI SYSTEM) 
    1. Check for DTCs.

      w/ EGR System: Refer to DTC CHECK / CLEAR [10/2014 - 05/2019] , or refer to DTC CHECK / CLEAR [05/2019 - ]

      w/o EGR System:

      Powertrain > Engine and ECT > Trouble Codes 

      OK

      No DTCs are output.

      Result

      Proceed to
      OK
      NG

    Result:

    GO TO SFI SYSTEM. Refer to  HOW TO PROCEED WITH TROUBLESHOOTING [10/2014 - ] 

    Result: 

    OK 

    See step  3

  3. PERFORM ACTIVE TEST USING TECHSTREAM (WATER TEMPERATURE METER OPERATION) 
    1. Using the Techstream, perform the Active Test.

      Refer to DATA LIST / ACTIVE TEST [10/2014 - ]

      Body Electrical > Combination Meter > Active Test 

      Tester Display Measurement Item Control Range Diagnostic Note
      Water Temperature Meter Operation Engine coolant temperature receiver gauge OFF, LOW, NORMAL, HIGH -

      Body Electrical > Combination Meter > Active Test 

      Tester Display
      Water Temperature Meter Operation

      OK

      Engine coolant temperature receiver gauge indication is normal.

      Result

      Proceed to
      OK
      NG

    Result: 

    NG 

    REPLACE COMBINATION METER ASSEMBLY. Refer to  REMOVAL [10/2014 - 09/2017]  , or refer to  REMOVAL [09/2017 - ] 

    Result: 

    OK 

    See step  4

  4. READ VALUE USING TECHSTREAM (COOLANT TEMP, COOLANT TEMPERATURE) 
    1. Using the Techstream, read the Data List.

      Refer to DATA LIST / ACTIVE TEST [10/2014 - ]

      Powertrain > Engine and ECT > Data List 

      Tester Display Measurement Item Range Normal Condition Diagnostic Note
      Coolant Temp Engine coolant temperature Min.: -40°C (-40°F), Max: 215°C (419°F) 75 to 100°C (167 to 212°F): After warming up the engine -

      Body Electrical > Combination Meter > Data List 

      Tester Display Measurement Item Range Normal Condition Diagnostic Note
      Coolant Temperature Engine coolant temperature Min.: 0°C (0°F), Max.: 127.5°C (261.5°F) 75 to 100°C (167 to 212°F): After warming up the engine -

      Powertrain > Engine and ECT > Data List 

      Tester Display
      Coolant Temp

      Body Electrical > Combination Meter > Data List 

      Tester Display
      Coolant Temperature

      HINT: 

      • When the Data List values of the ECUs match, an internal malfunction of the ECM is suspected.
      • When the Data List values of the ECUs do not match, a signal output error of the ECM or an internal malfunction of the combination meter assembly is suspected.

      OK

      The Data List values of the ECUs do not match.

      Result

      Proceed to
      OK
      NG

    Result: 

    NG 

    REPLACE ECM. Refer to  REMOVAL [10/2014 - ] 

    Result: 

    OK 

    See step  5

  5. CHECK COMBINATION METER ASSEMBLY 
    1. Replace the combination meter assembly.

      Refer to REMOVAL [10/2014 - 09/2017] , or refer to REMOVAL [09/2017 - ]

    2. Check that the operation of the engine coolant temperature receiver gauge returns to normal.

      OK

      The operation of the engine coolant temperature receiver gauge returns to normal.

      Result

      Proceed to
      OK
      NG

    Result: 

    OK 

    END (COMBINATION METER ASSEMBLY IS DEFECTIVE) 

    Result:
