Engine Coolant Temperature Receiver Gauge Malfunction: Procedure

1. Check if a CAN communication DTC is output. Refer to DIAGNOSIS SYSTEM [06/2012 - ] .
   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 

1. Operate the Techstream according to the display and select the Active Test. Refer to DATA LIST / ACTIVE TEST [06/2012 - ] .
   COMBINATION METER
   
   

   Tester Display	Test Part	Control Range	Diagnostic Note
   Water Temperature Meter Operation	Engine coolant temperature receiver gauge	Low, Normal, High	Confirm that the vehicle is stopped with the engine idling.

   OK

   Engine coolant temperature receiver gauge indication is normal.

NG → See step   5 

OK: Go to next step 

1. Operate the Techstream according to the display and select the Data List. Refer to DATA LIST / ACTIVE TEST [06/2012 - ] .
   COMBINATION METER
   
   

   Tester Display	Measurement Item/Range	Normal Condition	Diagnostic Note
   Coolant Temperature	Engine coolant temperature/0 to 127.5°C (32 to 261.5°F)	After warming up: 80 to 95°C (176 to 203°F)	If the value is -40°C (-40°F), the sensor circuit is open. If the value is 140°C (284°F) or higher, the sensor circuit is shorted.

   OK

   Engine coolant temperature value displayed on the Techstream is almost the same as the engine coolant temperature receiver gauge indication.

2. Record the temperature displayed on the Techstream.

NG → See step   5 

OK: Go to next step 

1. Operate the Techstream according to the display and select the Data List. Refer to DATA LIST / ACTIVE TEST [06/2012 - ] .
   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)	After warming up: 80 to 100°C (176 to 212°F)	If the value is -40°C (-40°F), the sensor circuit is open. If the value is 140°C (284°F) or higher, the sensor circuit is shorted.

   OK

   Engine coolant temperature value displayed on the Techstream is almost the same as the previously recorded Techstream indication (Body Electrical / Combination Meter / Data List / Coolant Temperature).
