CAUTION / NOTICE / HINT

The necessary procedures (adjustment, calibration, initialization or registration) that must be performed after parts are removed and installed, or replaced during port fuel injector 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
Battery terminal is disconnected/reconnected	Reset back door close position	Power Back Door System	(202111,999999,_59,_111831,_0505274,RM100000001ZMEG,)
· Replacement of port fuel injector assembly · Replacement of No. 2 fuel pressure sensor · Replacement of EGR valve assembly · Gas leak from exhaust system is repaired	Inspection after repair	· Poor idle, etc. · Engine start function, etc.	(202303,999999,_51,_111785,_0504416,RM1000000029BFF,)

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:: ·

This procedure includes the removal of small-head bolts. Refer to Small-Head Bolts of Basic Repair Hint to identify the small-head bolts.
