METER / GAUGE SYSTEM Fuel Receiver Gauge Malfunction

WIRING DIAGRAM

INSPECTION PROCEDURE

PROCEDURE

1. PERFORM ACTIVE TEST USING GTS (FUEL METER OPERATION)

   
   

   1. Use the Active Test to check the operation of the fuel receiver gauge Click here.

      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 or Sender F	-

      OK
      Fuel receiver gauge is normal.

   
   

   NG

   REPLACE COMBINATION METER ASSEMBLY Click here

   OK

2. READ VALUE USING GTS (FUEL INPUT)

   
   

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

      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: Liters

      OK
      Fuel amount value displayed on the GTS is almost the same as needle indication.

3. CHECK HARNESS AND CONNECTOR (COMBINATION METER ASSEMBLY - FRONT FUEL MAIN AND RETURN TUBE SUB-ASSEMBLY)

   
   

   1. Disconnect the H20 combination meter assembly connector.

   2. Disconnect the h1*1 or h2*2 front fuel main and return tube sub-assembly connector.

      
      

      • *1: Engine Type Diesel

      • *2: Engine Type Gasoline

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

      Standard Resistance
      Engine Type Diesel Tester Connection Condition Specified Condition H20-33 (FUEL) - h1-2 Always Below 1 Ω H20-34 (E2) - h1-3 H20-33 (FUEL) or h1-2 - Body ground Always 10 kΩ or higher H20-34 (E2) or h1-3 - Body ground
      Engine Type Gasoline Tester Connection Condition Specified Condition H20-33 (FUEL) - h2-2 Always Below 1 Ω H20-34 (E2) - h2-3 H20-33 (FUEL) or h2-2 - Body ground Always 10 kΩ or higher H20-34 (E2) or h2-3 - Body ground

   
   

   NG

   REPAIR OR REPLACE HARNESS OR CONNECTOR

   OK

4. INSPECT FRONT FUEL MAIN AND RETURN TUBE SUB-ASSEMBLY

   
   

   1. 

      Remove the front fuel main and return tube sub-assembly.
