Engine Coolant Temperature Gauge Malfunction [09/2014 - 10/2015]: Procedure

1. Check if a CAN communication DTC is output (Refer to DIAGNOSIS SYSTEM [09/2014 - 10/2015] ).
   RESULT
   
   

   Result	Proceed to
   CAN communication DTC is not output	A
   CAN communication DTC is output	B

Result: 

B 

GO TO CAN COMMUNICATION SYSTEM 

(Refer to HOW TO PROCEED WITH TROUBLESHOOTING [09/2014 - 10/2015] )

Result: 

A 

See step  2

1. Use the Active Test to check the operation of the engine coolant temperature receiver gauge (Refer to DATA LIST / ACTIVE TEST [09/2014 - 10/2015] ).
   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.

Result: 

NG 

REPLACE COMBINATION METER ASSEMBLY 

(Refer to REMOVAL [09/2014 - ] )

Result: 

OK 

See step  3

1. Use the Data List to check the engine coolant temperature (Refer to DATA LIST / ACTIVE TEST [09/2014 - 10/2015] ).
   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.

Result: 

NG 

REPLACE COMBINATION METER ASSEMBLY 

(Refer to REMOVAL [09/2014 - ] )

Result: 

OK 

See step  4

1. Use the Data List to check the engine coolant temperature (Refer to DATA LIST / ACTIVE TEST [09/2014 - 10/2015] ).
   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.

Result: 

NG 

GO TO SFI SYSTEM 

(Refer to HOW TO PROCEED WITH TROUBLESHOOTING [09/2014 - 10/2015] )

Result: 

OK 

See step  5

1. Replace the combination meter assembly with a new or normally functioning one (Refer to REMOVAL [09/2014 - ] ).

   OK

   The operation of the engine coolant temperature gauge returns to normal.

Result: 

OK 

END (COMBINATION METER ASSEMBLY WAS DEFECTIVE) 

Result: 

NG 

REPLACE ECM 

(Refer to REMOVAL [09/2014 - 10/2015] )
