.
- PERFORM ACTIVE TEST USING TECHSTREAM (WATER TEMPERATURE METER OPERATION)
- Connect the Techstream to the DLC3.
- Turn the ignition switch to ON.
- Turn the Techstream on.
- Enter the following menus: Body Electrical / Combination Meter / Active Test.
- According to the display on the Techstream, perform the Active Test.COMBINATION METER
Tester Display Test Part Control Range Diagnostic Note Water Temperature Meter Operation Engine coolant temperature receiver gauge LOW, NORMAL or HIGH Perform the test with the vehicle stopped and the engine idling. OK
Engine coolant temperature receiver gauge indication is normal.

- READ VALUE USING TECHSTREAM (COOLANT TEMPERATURE)
- Connect the Techstream to the DLC3.
- Turn the ignition switch to ON.
- Turn the Techstream on.
- Enter the following menus: Body Electrical / Combination Meter / Data List.
- According to the display on the Techstream, read the Data List.COMBINATION METER
Tester Display Measurement Item/Range Normal Condition Diagnostic Note Coolant Temperature Engine coolant temperature/
Min.: 0 (32), Max.: 127.5 (261.5)After warming up: 75 to 105 (167 to 221) Unit: °C (°F) OK
Engine coolant temperature value displayed on the Techstream is almost the same as the engine coolant temperature receiver gauge indication.
