Fuel Receiver Gauge Malfunction: Procedure

1. Check DTC.Refer to DTC CHECK / CLEAR .
   RESULT
   
   

   Result	Proceed to
   DTC B1500 is not output	A
   DTC B1500 is output	B

B → See step   6 

A: Go to next step 

1. Connect the Techstream to the DLC3.
2. Turn the ignition switch to ON.
3. Turn the Techstream on.
4. Enter following menus: Body Electrical / Combination Meter / Active Test.
5. According to the display on the Techstream, perform the Active Test.

   Tester Display	Test Part	Control Range	Diagnostic Note
   Fuel Meter Operation	Fuel receiver gauge	EMPTY/ 1/2 /FULL	Perform the test with the vehicle stopped and the engine idling.

   OK

   Fuel receiver gauge indication is normal.

2. Check that the float moves smoothly between F and E.
3. Measure the resistance according to the value(s) in the table below.

   Standard Resistance

   Tester Connection	Float Level	Float Position (mm (in.))	Specified Condition
   1 - 2	F	181.9 to 177.9 (7.161 to 7.003)	12.0 to 18.0 Ω
   	1/2	99.5 (3.917)	212.5 Ω
   	Warning	32.3 (1.271)	375.4 Ω
   	E	0 (0)	405.0 to 415.0 Ω

4. Reinstall the fuel sender gauge assembly.

   *c	Connector B

3. Reinstall the fuel suction plate sub-assembly.

NG → See step   9 

OK: Go to next step 

1. Disconnect the E13 combination meter assembly connector.
2. Disconnect the L5 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
   E13-16 (L) - L5-2 (FS)	Always	Below 1 Ω
   E13-16 (L) - Body ground	Always	10 kΩ or higher
   E13-5 (E3) - L5-3 (FE)	Always	Below 1 Ω
   E13-5 (E3) - Body ground	Always	10 kΩ or higher
   E13-21 (ES) - Body ground	Always	Below 1 Ω

4. Reconnect the fuel suction plate sub-assembly connector.
5. Reconnect the combination meter assembly connector.

NG → REPAIR OR REPLACE HARNESS OR CONNECTOR 

OK → See step   10
