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
- Check for DTCs.
- CHECK FOR DTC (SFI SYSTEM)
- 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:
NG
GO TO SFI SYSTEM. Refer to HOW TO PROCEED WITH TROUBLESHOOTING [10/2014 - ]
Result:
OK
See step 3
- Check for DTCs.
- PERFORM ACTIVE TEST USING TECHSTREAM (WATER TEMPERATURE METER OPERATION)
- 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
- Using the Techstream, perform the Active Test.
- READ VALUE USING TECHSTREAM (COOLANT TEMP, COOLANT TEMPERATURE)
- 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
- Using the Techstream, read the Data List.
- CHECK COMBINATION METER ASSEMBLY
- Replace the combination meter assembly.
Refer to REMOVAL [10/2014 - 09/2017] , or refer to REMOVAL [09/2017 - ]
- 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:
NG
REPLACE ECM. Refer to REMOVAL [10/2014 - ]
- Replace the combination meter assembly.
