NR Series FUEL FUEL PUMP(for High Pressure) REMOVAL

CAUTION / NOTICE / HINT

The necessary procedures (adjustment, calibration, initialization or registration) that must be performed after parts are removed and installed, or replaced during fuel pump assembly removal/installation are shown below.

Necessary Procedures After Parts Removed/Installed/Replaced
Replaced Part or Performed Procedure	Necessary Procedure	Effect/Inoperative Function when Necessary Procedure not Performed	Link
· Replacement of fuel pump assembly · Replacement of throttle body with motor assembly · Cleaning the deposits from the throttle body with motor 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.

·

To prevent serious injury due to fuel spray from the high-pressure fuel lines, always discharge fuel system pressure before removing any fuel system components.

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
