   Refer to DIAGNOSIS SYSTEM [11/2013 - 10/2015] .

   Refer to DIAGNOSIS SYSTEM [10/2015 - 08/2016] .

   Refer to DIAGNOSIS SYSTEM [08/2016 - ] .

   Result	Proceed to
   	CAN communication system DTC is not output
   	CAN communication system DTC is output

Result: 

CAN communication system DTC is output 

GO TO CAN COMMUNICATION SYSTEM: 

Refer to HOW TO PROCEED WITH TROUBLESHOOTING [12/2012 - 10/2015] or HOW TO PROCEED WITH TROUBLESHOOTING [10/2015 - ] .

Result: 

CAN communication system DTC is not output 

See step  2

1. Check if a SFI system DTC is output.

   Refer to DTC CHECK / CLEAR [12/2012 - ] .

   Powertrain > Engine and ECT > Trouble Codes 

   Result	Proceed to
   	SFI system DTC is not output
   	SFI system DTC is output

Result: 

SFI system DTC is output 

GO TO SFI SYSTEM. 

Refer to HOW TO PROCEED WITH TROUBLESHOOTING [12/2012 - ] .

Result: 

SFI system DTC is not output 

See step  3

1. Using the Techstream, perform the Active Test:

   Refer to DATA LIST / ACTIVE TEST [12/2012 - 10/2015] .

   Refer to DATA LIST / ACTIVE TEST [10/2015 - 08/2016] .

   Refer to DATA LIST / ACTIVE TEST [08/2016 - ] .

   Body Electrical > Combination Meter > Active Test 

   Tester Display	Measurement Item	Control Range	Diagnostic Note
   Water Temperature Meter Operation	Engine coolant temperature receiver gauge	OFF, LOW, NORMAL or HIGH	-

   Body Electrical > Combination Meter > Active Test 

   Tester Display
   Water Temperature Meter Operation

   OK

   Engine coolant temperature receiver gauge indication is normal.

   Result	Proceed to
   	OK
   	NG

Result: 

NG 

REPLACE COMBINATION METER ASSEMBLY.  Refer to REMOVAL [12/2012 - ] .

Result: 

OK 

See step  4

1. Using the Techstream, read the Data List.

   Refer to DATA LIST / ACTIVE TEST [12/2012 - 10/2015] .

   Refer to DATA LIST / ACTIVE TEST [10/2015 - 08/2016] .

   Refer to DATA LIST / ACTIVE TEST [08/2016 - ] .

   Body Electrical > Combination Meter > Data List 

   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)	-

   Powertrain > Engine and ECT > Data List 

   Tester Display	Measurement Item	Range	Normal Condition	Diagnostic Note
   Coolant Temp	Engine coolant temperature	Min.: -40°C (-40°F), Max: 215°C (419°F)	60 to 90°C (140 to 194°F): After warming up engine	-

   Body Electrical > Combination Meter > Data List 

   Tester Display
   Coolant Temperature

   Powertrain > Engine and ECT > Data List 

   Tester Display
   Coolant Temp

   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.

   Result	Proceed to
   	The Data List values of the ECUs do not match
   	The Data List values of the ECUs match

Result: 

The Data List values of the ECUs do not match. 

REPLACE COMBINATION METER ASSEMBLY.  Refer to REMOVAL [12/2012 - ] .

Result: 

The Data List values of the ECUs match. 

See step  5

1. Replace the combination meter assembly with a new or normally functioning one.

   Refer to REMOVAL [12/2012 - ] .

   OK

   The operation of the tachometer returns to normal.

   Result	Proceed to
   	OK
   	NG

Result: 

OK 

END (COMBINATION METER ASSEMBLY WAS DEFECTIVE) 

Result: 

NG 

REPLACE ECM. Refer to  REMOVAL [12/2012 - ]  .
