Inspection Procedure

  1. CHECK CAN COMMUNICATION SYSTEM 
    1. Check for the DTC (See DTC CHECK/CLEAR  ).

      Result: 

      RESULT REFERENCE CHART

      Result Proceed to
      CAN communication system DTC is not output A
      CAN communication system DTC is output B

      B: Go to CAN COMMUNICATION SYSTEM  (See CAN COMMUNICATION SYSTEM )

      A: Go to Next Step 

  2. PERFORM ACTIVE TEST USING TECHSTREAM (FUEL RECEIVER GAUGE) 
    1. Operate the Techstream according to the steps on the display and select "Active Test".

      OK: 

      Needle indication is normal. 

      Combination Meter: 

      COMBINATION METER REFERENCE CHART

      Tester Display Test Part Control Range
      Fuel Meter Operation Fuel receiver gauge Empty, 1/2 or Full

      NG: REPLACE NO. 1 METER ECU (See  DISASSEMBLY   ) 

      OK: Go to Next Step 

  3. READ VALUE USING TECHSTREAM (FUEL SENDER GAUGE) 
    1. Operate the Techstream according to the display and select the "Data List".

      OK: 

      Fuel value displayed on Techstream is almost same as needle indication 

      Combination Meter: 

      COMBINATION METER REFERENCE CHART

      Tester Display Measurement Item/Range Normal Condition Diagnostic Note
      Fuel Input Fuel sender gauge (main) input signal/Min.: 0, Max.: 127.5 Fuel sender input value Unit: L

      NG: Go to step 4 

      OK: REPLACE NO. 1 METER ECU (See  DISASSEMBLY   ) 

  4. INSPECT FUEL SENDER GAUGE ASSEMBLY (MAIN) 
    1. Remove the fuel sender gauge (main) (See DISASSEMBLY ).
    2. Measure the resistance according to the value (s) in the table below.

      Standard resistance 

      STANDARD RESISTANCE REFERENCE CHART

      Tester Connection Condition Specified Condition
      1 - 2 Float level is F (upper) 6.5 to 8.5 Ω
      Between float level is F (upper) and E (lower) 91.0 to 102.2 Ω
      Float level is E (lower) 184.8 to 188.8 Ω

      NG: REPLACE FUEL SENDER GAUGE ASSEMBLY (MAIN)  (See DISASSEMBLY )

      OK: Go to Next Step 

  5. INSPECT FUEL SENDER GAUGE ASSEMBLY (SUB) 
    1. Remove the fuel sender gauge (sub) (See DISASSEMBLY ).
    2. Measure the resistance according to the value (s) in the table below.

      Standard resistance 

      STANDARD RESISTANCE REFERENCE CHART

      Tester Connection Condition Specified Condition
      1 - 2 Float level is F (upper) 6.5 to 8.5 Ω
      Between float level is F (upper) and E (lower) 112.7 to 125.7 Ω
      Float level is E (lower) 220.7 to 225.7 Ω

    1. Disconnect the S61 junction block connector.
    2. Disconnect the S11 and R10 gauge connectors.
    3. Measure the resistance according to the value (s) in the table below.

      Standard resistance 

      STANDARD RESISTANCE REFERENCE CHART

      Tester Connector Condition Specified Condition
      S61-7 (FR) - S11-2 Always Below 1 Ω
      S61-18 (FE) - R10-2
      S61-7 (FR) or S11-2 - Body ground Always 10 kΩ or higher
      S61-18 (FE) or R10-2 - Body ground

      NG: REPAIR OR REPLACE HARNESS OR CONNECTOR 

      OK: Go to Next Step 

  7. CHECK HARNESS AND CONNECTOR (FUEL SENDER GAUGE (MAIN) - FUEL SENDER GAUGE (SUB)) 
    1. Disconnect the S11 and R10 gauge connectors.
    2. Measure the resistance according to the value (s) in the table below.

      Standard resistance 

      STANDARD RESISTANCE REFERENCE CHART

      Tester Connection Condition Specified Condition
      S11-3 - R10-1 Always Below 1 Ω
      S11-3 or R10-1 -Body ground Always 10 kΩ or higher

      NG: REPAIR OR REPLACE HARNESS OR CONNECTOR 

      OK: Go to Next Step 

  8. REPLACE NO. 1 METER ECU 
    1. Temporarily replace the No. 1 meter ECU with a new one (See DISASSEMBLY  ).
  9. CHECK NO. 1 METER ECU (FUEL RECEIVER GAUGE) 
    1. Check that the operation of the fuel sender gauge in the meter returns to normal (See OPERATION CHECK  ).

      OK: 

      Operation of the fuel sender gauge returns to normal. 

      NG: REPLACE LUGGAGE ROOM JUNCTION BLOCK ASSEMBLY (REAR JUNCTION BLOCK ECU) 

      OK: END (NO. 1 METER ECU IS DEFECTIVE)
