1. Disconnect the F9 gauge connector.
2. Check the meter indicator condition.

   OK

   Wire Connection	Condition	Specified Condition
   2 - 3	Short circuit (Ignition switch ON)	Fuel gauge indicator "F" or more (combination meter)

3. Measure the voltage of the wire harness side connector.

   Standard voltage

   Tester Connection	Condition	Specified Condition
   2 - Body ground	Ignition switch ON	11 to 14 V

NG → See step   3 

OK: Go to next step 

1. Remove the fuel sender gauge assembly.

2. Check that the float moves smoothly between F and E.
3. Measure the resistance between terminals 2 and 3 of the gauge.

   Standard resistance

   Float Level	Specified Condition
   SF	3.0 to 5.0 Ω
   Between E and F	3.0 to 111 Ω
   SE	109 to 111 Ω

NG → REPLACE FUEL SENDER GAUGE ASSEMBLY 

OK → REPLACE COMBINATION METER ASSEMBLY 

1. Disconnect the C6 meter connector.

2. Disconnect the F9 gauge connector.
3. Measure the resistance of the wire harness side connectors.

   Standard resistance

   Tester Connection	Specified Condition
   C6-23 - F9-2	Below 1 Ω
   C6-2 - F9-3	Below 1 Ω

NG → REPAIR OR REPLACE HARNESS AND CONNECTOR 

OK → REPLACE COMBINATION METER ASSEMBLY
