Engine Coolant Temperature Gauge Malfunction: Procedure
- CHECK CAN COMMUNICATION SYSTEM
- Check if a CAN communication DTC is output. Refer to DIAGNOSIS SYSTEM [03/2012 - ]
.RESULT
Result Proceed to CAN communication DTC is not output A CAN communication DTC is output B
B → See step 8
A: Go to next step
- Check if a CAN communication DTC is output. Refer to DIAGNOSIS SYSTEM [03/2012 - ]
.
- PERFORM ACTIVE TEST USING TECHSTREAM (WATER TEMPERATURE METER OPERATION)
- Use the Active Test to check the operation of the engine coolant temperature receiver gauge. Refer to DATA LIST / ACTIVE TEST [03/2012 - ]
.COMBINATION METER
Tester Display Test Part Control Range Diagnostic Note Water Temperature Meter Operation Engine coolant temperature receiver gauge Low, Normal or High - OK
Engine coolant temperature receiver gauge indication is normal.
NG → See step 9
OK: Go to next step
- Use the Active Test to check the operation of the engine coolant temperature receiver gauge. Refer to DATA LIST / ACTIVE TEST [03/2012 - ]
.
- READ VALUE USING TECHSTREAM (COOLANT TEMPERATURE)
- Use the Data List to check the engine coolant temperature. Refer to DATA LIST / ACTIVE TEST [03/2012 - ]
.COMBINATION METER
Tester Display Measurement Item/Range Normal Condition Diagnostic Note Coolant Temperature Engine coolant temperature/0 to 127.5°C (0 to 261.5°F) After warming up: 75 to 100°C (167 to 212°F) - OK
Engine coolant temperature value displayed on the Techstream is almost the same as the engine coolant temperature receiver gauge indication.
NG → See step 9
OK: Go to next step
- Use the Data List to check the engine coolant temperature. Refer to DATA LIST / ACTIVE TEST [03/2012 - ]
.
- READ VALUE USING TECHSTREAM (COOLANT TEMP)
- Use the Data List to check the engine coolant temperature. Refer to DATA LIST / ACTIVE TEST [03/2012 - ]
.ENGINE AND ECT
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 - OK
Engine coolant temperature value displayed on the Techstream is almost the same as the previously recorded value displayed on the Techstream.
NG → See step 6
OK: Go to next step
- Use the Data List to check the engine coolant temperature. Refer to DATA LIST / ACTIVE TEST [03/2012 - ]
.
- CHECK COMBINATION METER ASSEMBLY
- Replace the combination meter assembly with a new or normally functioning one. Refer to REMOVAL [03/2012 - ]
.
OK
The operation of the engine coolant temperature gauge returns to normal.
NG → See step 7
OK → END (COMBINATION METER ASSEMBLY WAS DEFECTIVE)
- Replace the combination meter assembly with a new or normally functioning one. Refer to REMOVAL [03/2012 - ]
.
- GO TO SFI SYSTEM. Refer to HOW TO PROCEED WITH TROUBLESHOOTING [03/2012 - ]
- REPLACE ECM. Refer to REMOVAL [03/2012 - ]
- GO TO CAN COMMUNICATION SYSTEM. Refer to HOW TO PROCEED WITH TROUBLESHOOTING [03/2012 - ]
- REPLACE COMBINATION METER ASSEMBLY. Refer to REMOVAL [03/2012 - ]
