1. Check if a CAN communication DTC is output (Refer to DIAGNOSIS SYSTEM [08/2016 - 11/2017] Refer to DIAGNOSIS SYSTEM [11/2017 - 08/2018] Refer to DIAGNOSIS SYSTEM [08/2018 - ] ).
   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 [08/2016 - 11/2017]  Refer to  HOW TO PROCEED WITH TROUBLESHOOTING [11/2017 - ] 

Result: 

A 

See step  2

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. According to the display on the Techstream, perform the Active Test.
   COMBINATION METER
   
   

   Tester Display	Test part	Control Range	Diagnostic Note
   Fuel Meter Operation	Fuel receiver gauge	OFF, Sender E, Empty, Warning, 1/4, 1/2, 3/4, Full, Sender F	Operate with IG ON and the vehicle is stopped.

   OK

   Fuel receiver gauge indication is normal.

Result: 

NG 

REPLACE COMBINATION METER ASSEMBLY 

(Refer to REMOVAL [12/2015 - ] )

Result: 

OK 

See step  3

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 / Data List.
5. According to the display on the Techstream, read the Data List.
   COMBINATION METER
   
   

   Tester Display	Measurement Item/Range	Normal Condition	Diagnostic Note
   Fuel Input	Fuel input signal/ Min.: 0, Max.: 127.5	Current fuel level displayed	Unit: Liter

   OK

   Fuel level signal displayed on the Techstream is almost the same as fuel receiver gauge indication.

Result: 

NG 

REPLACE COMBINATION METER ASSEMBLY 

(Refer to REMOVAL [12/2015 - ] )

Result: 

OK 

See step  4

1. Disconnect the D145 combination meter assembly connector.
2. Disconnect the g4 fuel suction with pump and gauge tube assembly connector.
3. Measure the resistance according to the value(s) in the table below.

   Standard Resistance

   Tester Connection	Condition	Specified Condition
   D145-14 (FR) - g4-2	Always	Below 1 Ω
   D145-14 (FR) or g4-2 - Body ground	Always	10 kΩ or higher
   D145-15 (FE) - g4-3	Always	Below 1 Ω
   D145-15 (FE) or g4-3 - Body ground	Always	10 kΩ or higher

Result: 

NG 

REPAIR OR REPLACE HARNESS OR CONNECTOR 

Result: 

OK 

See step  5

1. Remove the fuel sender gauge assembly (Refer to REMOVAL [08/2016 - ] ).
2. Inspect the fuel sender gauge assembly (Refer to INSPECTION [08/2016 - ] ).

Result: 

NG
