   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

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
   Engine Rpm	Engine speed	Min.: 0 rpm, Max.: 12750 rpm	Actual engine speed	-

   Powertrain > Engine and ECT 

   Tester Display	Measurement Item	Range	Normal Condition	Diagnostic Note
   Engine Speed	Engine speed	Min.: 0 rpm, Max.: 16383 rpm	750 to 850 rpm: Idling with warm engine	-

   Body Electrical > Combination Meter > Data List 

   Tester Display
   Engine Rpm

   Powertrain > Engine and ECT > Data List 

   Tester Display
   Engine Speed

   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 - ]

2. Check the tachometer operation.

   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.
