Standard resistance:





NG -- REPLACE FUEL SENDER GAUGE ASSEMBLY (SUB) Removal
OK -- Continue to next step.

8. REPLACE COMBINATION METER ASSEMBLY

(a) Temporarily replace the combination meter with a new one Removal.

NEXT -- Continue to next step.

9. CHECK COMBINATION METER ASSEMBLY (FUEL RECEIVER GAUGE)

Removal

(a) Check that the operation of the fuel sender gauge in the meter returns to normal 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 (COMBINATION METER IS DEFECTIVE)
