4. Anti-rust treatment after installation

(A) body sealer application

(A) body sealer application

Purpose: for water-proofing and anti-rust measures, always apply the body sealer to the body panel seams and hems of the doors, hood, etc.

Notice

: apply body sealer neatly to parts that require a high quality appearance.

(B) undercort application

(B) undercort application

Purpose:

to prevent corrosion and protect the body from gravel, always apply a sufficient undercoating to the areas indicated.

(C) vehicle body anti-rust agent application

Purpose:

the purpose is to protect areas from rust which are difficult to paint such as the backside of the box-shaped cross section frame parts.

Method

: apply anti-rust agent through the service holes and/or installation holes of the parts.

5. Headlight bracket repair

Hint:

if the installation area of the headlight assembly is damaged, use the supply retainer for low-cost repair.
Ensure that the headlight assembly is not damaged.

(A) install upper headlight protector

(A) install upper headlight protector retainer

(1) cut off the part shaded in the illustration and smooth with sandpaper.

Notice

: after cutting off the part, place the upper headlight protector retainer against the bosses and gradually file away the old bracket if it interferes with the installation of the supply bracket.

(2) Install the upper headlight protector retainer with the

(2) Install the upper headlight protector retainer with the 2 screws.

(B) install lower headlight protector

(B) install lower headlight protector retainer

(1) cut off the part shaded in the illustration and smooth with sandpaper.

Notice

: after cutting off the part, place the lower headlight protector retainer against the bosses and gradually file away the old bracket if it interferes with the installation of the supply bracket.

(2) Install the lower headlight protector retainer with the 2

(2) Install the lower headlight protector retainer with the 2 screws.

(C) install lower headlight bracket

(1) cut off the part shaded in the illustration and smooth with sandpaper.

Notice

: after cutting off the part, place the lower headlight bracket against the bosses and gradually file away the old bracket if it interferes with the installation of the supply bracket.

(2) Install the lower headlight bracket with the 2 screws.

6. Procedures necessary when ecu or other parts are replaced

(a) the work list

(1) each inspection procedure refers to the toyota repair manual.

Replacement part	Necessary procedure	Effect/inoperative function when necessary procedures are not performed	Note
Ecm	Vehicle identification number (vin) registration	Mil comes on	Using the techstream
	Ecu commnication id registration	Wireless door lock control system (4) smart key system (4) engine start	—
	Reset memory (*1)	Large shift shock the deterioration of fuel efficiency	Using the techstream
Automatic transmission assembly (1) engine assembly (1)	Reset memory	Large shift shock the deterioration of fuel efficiency	Using the intelligent tester
Tire pressure warning ecu	Register transmitter ids Initialize tire pressure warning system	When dtc detection conditions of “transmitter id not received” dtc are met, tpws indicator blinks for 1 minute, and then illuminates tire pressure monitoring function	—
Tire pressure warning valve and transmitter	Register transmitter ids Initialize tire pressure warning system	When dtc detection conditions of “transmitter id not received” dtc are met, tpws indicator blinks for 1 minute, and then illuminates Tire pressure monitoring function of replaced wheel	Even if only one wheel is replaced, ids for all 4 wheels must be registered
Brake actuator assembly (skid control ecu)	Perform yaw rate and acceleration sensor zero point calibration	Vsc off indicator light blinks Vsc disabled or malfunctioning	Perform yaw rate and acceleration sensor zero point calibration with the ignition switch on (engine stopped).
Yaw rate and acceleration sensor front wheel alignment adjustment	Clear zero point calibration data Perform yaw rate and acceleration sensor zero point calibration	Vsc off indicator light blinks Vsc disabled or malfunctioning	Perform yaw rate and acceleration sensor zero point calibration with the ignition switch on (engine stopped)
Power steering ecu (2) steering column (2)	Perform rotation angle sensor initialization and torque sensor zero point calibration.	P/s warning light comes on Eps control	Dtc (c1515/c1525) will be stored when the power steering ecu is replaced
Power steering ecu (*3)	Assist map writing Torque sensor zero point calibration	P /s warning light comes on Eps control	Dtc (c1515/c1525) will be stored when the power steering ecu is replaced
Steering column (*3)	Torque sensor zero point calibration	Steering effort is different between turning steering wheel to left and right	—
Door control transmitter (5) door control receiver (5)	Perform identification code registration (key code) Refer to wireless door lock control system “registration” procedures	Wireless door lock control system	—
Steering lock actuator (steering lock ecu) (*4)	Ecu code registration	Engine start	—
Certification ecu (4) electrical key transmitter (4)	Key id registration	Wireless door lock control system smart key system engine start	—
Id code box (*4)	Ecu code registration Ecu communication id registration	Wireless door lock control system smart key system engine start	—
Occupant classification ecu	Perform zero point calibration registration ecu data	Occupant classification system passenger airbag on/off indicator airbag system (front passenger side) seat belt warning system (front passenger side)	—
Sliding roof drive gear (sliding roof ecu) sliding roof housing sliding roof drive cable	Perform sliding roof drive gear reset.	Automatic open/close function of roof glass jam protection function operation function after ignition switch off	Necessary when removed and installed (not necessary when the sliding roof drive gear (sliding roof ecu) is removed and installed together with the sliding roof housing.)
