Fuel Receiver Gauge Malfunction: Procedure

1. Check if CAN communication DTC is output. Refer to DIAGNOSIS SYSTEM .

   Result

   Result	Proceed to
   CAN communication DTC is not output	A
   CAN communication DTC is output	B. Refer to DIAGNOSTIC TROUBLE CODE CHART

B → GO TO CAN COMMUNICATION SYSTEM 

A: Go to next step 

1. Connect Techstream to the DLC3.
2. Ignition switch on (IG).
3. Turn Techstream on.
4. Enter 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
   Fuel Meter Operation	Fuel receiver gauge	EMPTY, 1/2, FULL	-

   OK

   Needle indication is normal.

NG → REPLACE COMBINATION METER ASSEMBLY 

OK: Go to next step 

1. Connect Techstream to the DLC3.
2. Ignition switch on (IG).
3. Turn Techstream on.
4. Enter following menus: 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
   Fuel Input	Fuel input signal Min.: 0, Max.: 255	Fuel gauge indicates (E): 35 Fuel gauge indicates (3/4): 85 Fuel gauge indicates (1/2): 145 Fuel gauge indicates (1/4): 186 Fuel gauge indicates (E): 206	-

   OK

   Fuel value signal displayed on Techstream is almost the same as needle indication.

NG → See step   6 

OK: Go to next step 

1. Disconnect the F2 and fuel sender gauge assesmbly connectors.

2. Measure the resistance according to the value(s) in the table below.

   Standard resistance

   Tester Connection	Condition	Specified Condition
   F2-15 (FR) - 2	Always	Below 1 Ω
   F2-16 (FE) - 1	Always	Below 1 Ω
   2 - Body ground	Always	10 kΩ or higher
   F2-16 - 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. Remove the fuel sender gauge assembly.
3. Check that the float moves smoothly between F and E.
4. Measure the resistance between the terminals 1 and 2 of connector according to the value(s) in the table below.

   Standard resistance

   Float Level	Resistance (Ω)
   F	13.5 to 16.5
   Between E and F	13.5 to 414.5 (Gradually changes)
   E	405.5 to 414.5

NG → REPLACE FUEL SENDER GAUGE ASSEMBLY 

OK: Go to next step 

1. Replace the combination meter assembly to a new one or a normal one.

   OK

   The operation of the combination meter assembly returns to normal.

NG → REPLACE ECM 

OK → END
