Fuel Receiver Gauge Malfunction [08/2019 - ]: Procedure

1. Check if a CAN communication DTC is output.

   Refer to DIAGNOSIS SYSTEM [08/2019 - 08/2020] , or refer to DIAGNOSIS SYSTEM [08/2020 - 08/2021] , or refer to DIAGNOSIS SYSTEM [08/2021 - ]

   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 [08/2019 - ] 

Result: 

A 

See step  2

1. Using the Techstream, perform the Active Test.

   Refer to DATA LIST / ACTIVE TEST [08/2019 - ]

      *f	Fuel Gauge Operation (3/4)
      *g	Fuel Gauge Operation (Full)
      *h	Fuel Gauge Operation (Sender F)

      OK

      Fuel receiver gauge indication is normal.

   Result

   Proceed to
   OK
   NG

Result: 

NG 

REPLACE COMBINATION METER ASSEMBLY. Refer to  REMOVAL [08/2019 - ] 

Result: 

OK 

See step  3

1. Use the Data List to check if the fuel receiver gauge is operating properly.

   Refer to DATA LIST / ACTIVE TEST [08/2019 - ]

   BODY ELECTRICAL > COMBINATION METER > DATA LIST
   
   

   Tester Display	Measurement Item / Range	Normal Condition	Diagnostic Note
   Fuel Input	Fuel input signal / Min.: 0, Max. 127.5 L	Fuel receiver gauge indicates F: 78.3 Fuel receiver gauge indicates 3/4: 62.2 Fuel receiver gauge indicates 1/2: 46.1 Fuel receiver gauge indicates 1/4: 27.4 Fuel receiver gauge indicates E: 8.7	Unit: Liters

   OK

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

   Result

   Proceed to
   OK
   NG

Result: 

OK 

REPLACE COMBINATION METER ASSEMBLY. Refer to  REMOVAL [08/2019 - ] 

Result: 

NG 

See step  4

1. Disconnect the G3 combination meter assembly connector.
2. Disconnect the S4 fuel suction plate sub-assembly connector.
3. Measure the resistance according to the value(s) in the table below.

   Standard Resistance

   Tester Connection	Condition	Specified Condition
   G3-26 (L) - S4-2 (FS)	Always	Below 1 Ω
   G3-2 (E3) - S4-3 (FE)	Always	Below 1 Ω
   G3-20 (MGND) - Body ground	Always	Below 1 Ω
   G3-26 (L) or S4-2 (FS) - Body ground	Always	10 kΩ or higher

   Result

   Proceed to
   OK
   NG

Result: 

NG 

REPAIR OR REPLACE HARNESS OR CONNECTOR 

Result: 

OK 

See step  5

1. Remove the fuel sender gauge assembly.
