PROCEDURE

1. READ VALUE USING GTS (FUEL INPUT)

   
   

   1. Connect the GTS to the DLC3.

   2. Turn the power switch on (IG).

   3. Turn the GTS on.

   4. Enter the following menus: Body / 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.: 127.5	for Multi-information Display (Monochrome Type) Fuel sender gauge indicates F (1/1): 39.6 Fuel sender gauge indicates 3/4: 31.0 Fuel sender gauge indicates 1/2: 22.8 Fuel sender gauge indicates 1/4: 11.9 Fuel sender gauge indicates E (R): 5.1 for Multi-information Display (Color Type) 10th segment comes on: 39.6 or higher 9th segment comes on: 35.7 to 39.6 8th segment comes on: 31.8 to 35.7 7th segment comes on: 27.9 to 31.8 6th segment comes on: 24.0 to 27.9 5th segment comes on: 20.1 to 24.0 4th segment comes on: 16.2 to 20.1 3rd segment comes on: 12.3 to 16.2 2nd segment comes on: 8.4 to 12.3 1st segment comes on: 4.5 to 8.4	Unit: Liter

      Result
      Result Proceed to Fuel level data can be displayed on the GTS and DTC B1500 is output. A Fuel level data cannot be displayed on the GTS. B

3. CHECK HARNESS AND CONNECTOR (FUEL SENDER GAUGE ASSEMBLY - COMBINATION METER ASSEMBLY)

   
   

   1. Disconnect the P9 fuel sender gauge assembly connector.

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

      Standard Resistance
      Tester Connection Condition Specified Condition P9-2 (FS) - H19-27 (L) Always Below 1 Ω P9-3 (FE) - H19-30 (FE) Always Below 1 Ω P9-2 (FS) or H19-27 (L) - Body ground Always 10 kΩ or higher P9-3 (FE) or H19-30 (FE) - Body ground Always 10 kΩ or higher

   
   

   NG

   REPAIR OR REPLACE HARNESS OR CONNECTOR

   OK

   2. Check that the float moves smoothly between E and F.

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

      Standard Resistance
      Tester Connection Condition Specified Condition 1 - 2 Float level is F (upper) 13.5 to 16.5 Ω 1 - 2 Float level is between F (upper) and E (lower) 13.5 to 414.5 Ω (Gradually changes) 1 - 2 Float level is E (lower) 405.5 to 414.5 Ω

      Result
      Result Proceed to OK A NG (for 2ZR-FXE) B NG (for 5ZR-FXE) C
