EXCEPT FOR R9M : Component Function Check
INFOID:0000000010715026
1.
PERFORM COMPONENT FUNCTION CHECK (1)
1.
Turn ignition switch OFF.
2.
Disconnect fuel level sensor unit and fuel pump connector.
3.
Connect variable resistor between harness connector terminals located on the vehicle side of the fuel
level sensor unit.
4.
Set variable resistor according to the resistance value shown in the following table and turn ignition switch
ON.
*1: Reference resistance values used when the combination meter judges the indication position of the
fuel gauge.
*2: The inspection of 1/4 is not required.
Is the inspection result normal?
YES
>> GO TO 2.
NO
>> Refer to
MWI-136, "EXCEPT FOR R9M : Diagnosis Procedure"
2.
PERFORM COMPONENT FUNCTION CHECK (2)
Check the fuel level sensor unit and fuel pump, and fuel level sensor unit (sub). Refer to
FOR R9M : Component Inspection"
Is the inspection result normal?
YES
>> INSPECTION END
NO
>> Replace malfunctioning parts.
