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

B → See step   9 

A: Go to next step 

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

   Result	Proceed to
   Multiplex communication DTC is not output	A
   Multiplex communication DTC is output	B

B → See step   10 

A: Go to next step 

1. Connect the Techstream to the DLC3.
2. Turn the engine switch on (IG).
3. Turn the 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	Confirm that the vehicle is stopped, engine idling

   OK

   Fuel receiver gauge indication is normal.

NG → See step   11 

OK: Go to next step 

1. Connect the Techstream to the DLC3.
2. Turn the engine switch on (IG).
3. Turn the 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): 206	-
   		Fuel gauge indicates (1/2): 148
   		Fuel gauge indicates (F): 48

   OK

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

NG → See step   11 

OK: Go to next step 

1. Disconnect the P10 and Q14 connectors.

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

   Standard Resistance: Fuel Sender Gauge Assembly (Main)

   Tester Connection	Condition	Specified Condition
   Q14-2 (S) - Q14-3 (FE)	Always	6.5 to 229.6 Ω

   Standard Resistance: Fuel Sender Gauge Assembly (Sub)

   Tester Connection	Condition	Specified Condition
   P10-1 (FS) - P10-2 (E)	Always	6.5 to 184.9 Ω

NG → See step   12 

OK: Go to next step 

1. Disconnect the J34 connector.

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

   Standard Resistance

   Tester Connection	Condition	Specified Condition
   J34-19 (FR) - Q14-2 (S)	Always	Below 1 Ω
   Q14-3 (FE) - P10-1 (FS)	Always	Below 1 Ω
   P10-2 (E) - J34-2 (FE)	Always	Below 1 Ω
   Q14-2 (S) - Body ground	Always	10 kΩ or higher
   P10-1 (FS) - Body ground	Always	10 kΩ or higher
   J34-2 (FE) - 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. Inspect the fuel sender gauge assembly (main).
   1. Remove the fuel sender gauge assembly (main) with harness connected.
   2. Check that the float moves smoothly between F and E.
   3. Measure the resistance between the terminals 1 (FE) and 2 (S) of the connector according to the value(s) in the table below.

      Standard Resistance (Fuel Sender Gauge Assembly (Main))

      Float Level	Resistance (Ω)
      F	6.5 to 8.5
      Between E and F	6.5 to 229.6 (Gradually changes)
      E	224.6 to 229.6

3. Inspect the fuel sender gauge assembly (sub).
   1. Remove the fuel sender gauge assembly (sub).
   2. Check that the float moves smoothly between F and E.
   3. Measure the resistance between the terminals 1 (FS) and 2 (E) according to the value(s) in the table below.

      Standard Resistance (Fuel Sender Gauge Assembly (Sub))

      Float Level	Resistance (Ω)
      F	6.5 to 8.5
      Between E and F	6.5 to 184.9 (Gradually changes)
      E	180.9 to 184.9

NG → See step   12 

OK: Go to next step 

1. Replace the combination meter with a new or a known good one. Refer to REMOVAL - Step 9 .

   OK

   The operation of the combination meter returns to normal.

NG → See step   13 

OK → END
