   Result

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

B → See step   7 

A: Go to next step 

1. Connect the Techstream to the DLC3.
2. Turn the ignition switch to ON.
3. Turn the Techstream on.
4. Enter the following menus: Body Electrical / Combination Meter / Active Test.
5. Check the operation by referring to the table below.
   COMBINATION METER
   
   

   Tester Display	Test Part	Control Range	Diagnostic Note
   Tacho Meter Operation	Tachometer	0, 1000, 2000, 3000, 4000, 5000, 6000, 7000 (rpm)	-

   OK

   Tachometer indication is normal.

NG → See step   5 

OK: Go to next step 

1. Check if the SFI system output the DTC. Refer to DTC CHECK / CLEAR for 2AR-FE. Refer to DTC CHECK / CLEAR for 2GR-FE).

   Result

   Result	Proceed to
   The DTC is not output.	A
   The DTC is output (for 2AR-FE).	B
   The DTC is output (for 2GR-FE).	C

B → See step   6 

C → See step   8 

A: Go to next step 

1. Connect the Techstream to the DLC3.
2. Turn the ignition switch to ON.
3. Turn the Techstream on.
4. Enter the following menus:
   1. for Engine and ECT: Powertrain / Engine and ECT / Data List.
   2. for Combination Meter: Body Electrical / Combination Meter / Data List.
5. Check the values by referring to the table below.
   COMBINATION METER
   
   

   Tester Display	Measurement Item/Range	Normal Condition	Diagnostic Note
   Engine Rpm	Engine speed/Min.: 0 rpm, Max.: 12750 rpm	610 to 710 rpm: Idling (for 2AR-FE) 600 to 700 rpm: Idling (for 2GR-FE)	-

   ENGINE AND ECT
   
   

   Tester Display	Measurement Item/Range	Normal Condition	Diagnostic Note
   Engine Speed	Engine speed/Min.: 0 rpm, Max.: 16383 rpm	610 to 710 rpm: Idling (for 2AR-FE) 600 to 700 rpm: Idling (for 2GR-FE)	Stored as Freeze Frame Data When the crankshaft position sensor is malfunctioning, "Engine Speed" is approximately 0 rpm or varies greatly from the actual engine speed.
   	Results of real-vehicle check: Idling (warm up the engine and A/C off): 660 rpm

   Result

   Result	Proceed to
   The Data List values of the ECUs match.	A
   The Data List values of the ECUs do not match (for 2AR-FE).	B
   The Data List values of the ECUs do not match (for 2GR-FE).	C

   HINT: 

   • When the Data List values of the ECUs match, an internal malfunction of the combination meter assembly 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
