Tester Display Measurement Item Range Normal Condition Diagnostic Note Coolant Temperature 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 This is the engine coolant temperature.
HINT:- After warming up the engine, the engine coolant temperature is 75 to 100°C (167 to 212°F).
- After a long soak, the engine coolant temperature, intake air temperature and ambient temperature are approximately equal.
- If the value is -40°C (-40°F), or 135°C (275°F), the sensor circuit is open or shorted.
- Check if the engine overheats when the value indicates 135°C (275°F).

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:
OK
REPLACE ECM. Refer to REMOVAL [01/2017 - 05/2023] , or refer to REMOVAL [05/2023 - ]
Result:
NG
REPLACE COMBINATION METER ASSEMBLY. Refer to REMOVAL [01/2017 - ]
- Using the Techstream, read the Data List.
