Replaced Part or Performed Procedure	Necessary Procedure	Effect/Inoperative Function when Necessary Procedure not Performed	Link
Replacement of fuel pump with filter assembly	Inspection after repair	· Poor idle, etc. · Engine start function, etc.	(201906,999999,_51,_080777,_0393969,RM100000001I1RE,)

CAUTION:

·

Never perform work on fuel system components near any possible ignition sources.

·

Vaporized fuel could ignite, resulting in a serious accident.

·

Do not perform work on fuel system components without first disconnecting the cable from the negative (-) battery terminal.

·

Sparks could cause vaporized fuel to ignite, resulting in a serious accident.

NOTICE:

·

After the ignition switch is turned off, there may be a waiting time before disconnecting the negative (-) battery terminal.

Tube

Do not disconnect the tube shown in the illustration when disassembling the fuel suction tube with pump and gauge assembly. Doing so will cause reassembly of the fuel suction tube with pump and gauge assembly to be impossible as the tube is pressed into the fuel suction plate sub-assembly.

·

When replacing the fuel filter, replace it together with the fuel suction plate sub-assembly.

HINT:

When the cable is disconnected / reconnected to the battery terminal, systems temporarily stop operating. However, each system has a function that completes learning the first time the system is used.

Learning completes when vehicle is driven
