   CAN communication DTC is not output.	A
   CAN communication DTC is output.	B

B: GO TO CAN COMMUNICATION SYSTEM  (See HOW TO PROCEED WITH TROUBLESHOOTING )

A: Go to next step 

1. Connect Techstream to the DLC3.
2. Ignition switch on (IG).
3. Turn the tester on.
4. Enter following menus: Body Electrical / Combination Meter / Active Test.
5. Check the operation by referring to the table below.

   Combination Meter: 

   ACTIVE TEST TABLE
   
   

   Tester Display	Test Part	Control Range	Diagnostic Note
   Fuel Meter Operation	Fuel receiver gauge	EMPTY, 1/2, FULL	-

   OK: Needle indication is normal. 

NG: REPLACE COMBINATION METER ASSEMBLY  (See REMOVAL  )

OK: Go to next step 

1. Connect Techstream to the DLC3.
2. Ignition switch on (IG).
3. Turn the tester on.
4. Enter following menus: Body Electrical / Combination Meter / Data List.
5. Check the values by referring to the table below.

   Combination Meter: 

   DATA LIST TABLE
   
   

   Tester Display	Measurement Item/Range	Normal Condition	Diagnostic Note
   Fuel Input	Fuel input signal Min. 0, Max 127.5	Fuel gauge indicates (E) 7.5 (L) Fuel gauge indicates (1/2) 35.0 (L) Fuel gauge indicates (F) 62.9 (L)	-

   OK: Fuel value signal displayed on the tester is almost the same as needle indication. 

NG: REPLACE COMBINATION METER ASSEMBLY  (See REMOVAL  )

OK: Go to next step 

1. Disconnect the E1 and fuel sender gauge assembly connectors.
2. Measure the resistance according to the value(s) in the table below.

   Standard resistance 

   TESTER CONNECTION SPECIFIED CONDITION TABLE
   
   

   Tester Connection	Condition	Specified Condition
   E1-34 (FR) - 2	Always	Below 1 Ω
   E1-19 (FE) - 1	Always	Below 1 Ω
   2 - Body ground	Always	10 kΩ or higher
   E1-34 (FR) - Body ground	Always	10 kΩ or higher

NG: REPAIR OR REPLACE HARNESS OR CONNECTOR 

OK: Go to next step 

1. Disconnect the fuel sender gauge connector.
2. Measure the resistance between the terminals 1 and 2 of the connector according to the value(s) in the table below.

   Standard resistance 

   RESISTANCE SPECIFICATION TABLE
   
   

   Float Level	Resistance (Ω)
   F	3.0 to 5.0
   Between E and F	3.0 to 111.0 (Gradually changes)
   E	109.0 to 111.0

3. Remove the fuel sender gauge assembly (See REMOVAL ).
4. Check that the float moves smoothly between F and E.
5. Check the fuel sender gauge if there is deformation in the arm.

NG: REPLACE FUEL SENDER GAUGE ASSEMBLY  (See REMOVAL )

OK: Go to next step 

1. Replace the combination meter assembly with a new one or a normal one (See REMOVAL  ).

   OK: The operation of the combination meter assembly returns to normal. 

NG: REPLACE ECM (for 2GR-FE)  (See REMOVAL )

OK: END
