 REQUIRED TOOLS

☆Screwdriver (Flathead) ☆Screwdriver (Phillips) ☆Socket wrench
☆Box-end wrench/Combination wrench ☆Torque wrench ☆Nipper

☆Pliers ☆Hole saw (20mm) ☆Drill (1.5mm,3mm)
☆Punch ☆Pincers ☆Remover tool
☆Flathead screwdriver wrapped with protective tape ☆Fastener remover wrapped with protective tape ☆Flat, round file
☆Round file ☆Deburring Tool ☆Masking tape
☆Soft clean cloth ☆Electrical vinyl tape ☆Mat
☆IPA (Isopropyl alcohol)

WARNING

If the negative battery is
connected while performing the
work, it may cause electrocution
or other personal injuries.
Disconnect the negative cable
before /installation.

Before performing any work,
park the vehicle on level ground,
apply the parking brake
securely, and then block the
wheels.

Be careful when handling drills
and other sharp objects.
If not handled properly, it could
result in serious injury.

When connecting/disconnecting
connectors, grasp the connectors,
not the wires. Otherwise, a fire or
other accident could occur due to
a short circuit or poor contact.

Make sure the connector is
securely pressed in until a click
sound is heard.
Otherwise, a fire or other
accident may occur due to an
open circuit or poor contact.

Secure the wiring harness with
the tape (part included) so that
they are not left dangling.
Otherwise, a fire or other
accident may occur due to a
short circuit.

Do not pull a wiring harness with
excessive force. Doing so can
cause breakage which could
result in a short circuit or a fire.

CAUTION

Be sure to cover the vehicle body
with protectors or mats to prevent
stains, scratches and damage
when removing/installing the
vehicle parts.

Using improper tools may
damage parts. Use the correct
tool for the job.

When the negative battery cable
is removed, the initial value or
memory for the power windows,
clock, i-stop, steering angle
sensor reference point will be
cleared. Perform re-initialization.

Put the removed parts and the
kit accessory parts on a
protective sheet to prevent
scratches.

Wrap protective tape around
screwdrivers and fastener
remover tools to prevent
scratching the vehicle.

If there is dust, dirt or grease on
the adhesion surface, the
adhesive strength of the
double-sided adhesive tape will
be weakened. Wash and
degrease the surface of the
adhesion area before applying
the double-sided adhesive tape.
Be sure to wash interior and
exterior parts using IPA

(

isopropyl alcohol).

If tape or a mount base is
removed and then re-adhered,
the adhesive strength will be
weakened. Before adhering,
accurately determine the
adhesion position.

To assure sufficient
adhesiveness of the
double-sided adhesive tape,
press the adhesive surface of
the tape to the adhesion surface
evenly.
In particular, press sufficiently at
the ends of the double-sided
adhesive tape where the
adhesion surface is curved.

Make sure to remove burrs from
the surface so that the bumper
surface is smooth.

Advice

Refer to the Workshop Manual
for removal and installation of
vehicle parts.

5. Fold the electro tap in the direction of the arrow

shown in the figure and lock it.

6. Soundproof using urethane tape.

■ Branch connection procedure using electro-tap (Optional ON-OFF switch installed)

1. Put the harness to be branch-connected into the

guide groove.

2. Fold back the electro-tap from the A part as shown

in the figure.

3. Lock the electro-tap temporarily.

4. Firmly press the electro tap terminal using pliers.

 Firmly engage the lock part until a click sound

is heard.

CAUTION

 The temporary lock is provided on only one

side. Stop short of lockin

 When removing the rear combination light from

the body, it could interfere with the body and
cause scratching or damage to the body. When
removing the rear combination light from the
body, apply protective tape to the body.

CAUTION

 Fogging or condensation on the inside of the

rear combination lights may occur due to a
natural phenomenon occurring as a result of a
temperature difference between the interior and
exterior of the combination lights. However, it
has no effect on the light performance because
the temperature inside the rear combination
lights rises after illuminating a rear turn light or
a period of time has elapsed.

or individual differences (coating film/thickness)
occur, the blind spot monitoring control module
radar angle will deviate which could result in the
module not detecting a vehicle approaching from
the rear correctly. If the rear bumper is replaced,
perform the blind spot monitoring (BSM) radar
test.

3. Use two-component urethane paint. (Main

component: acrylicpolyol, curing agent: isocyanate)

 Maximum paint thickness: primer 30 um, paint and

coating 95 um in total.

4. When painting, use a spray gun to apply the paint

evenly.

 Paint infiltration into connector must be avoided;

pin contact must be guaranteed after painting.

 Maximum paint curing: 90 C for 1 hour.

5. After baking, do not touch the painted product until

it has cooled down completely.

 Hot storage temperature: 85 C.

6. When the painting is dried, remove the sensors and

the bezels from plastic base.

 Paint characteristics vary according to paint

type. Check manufacturer specifications
before painting.

CAUTION

 Do not use lacquer paints because their

weatherproofing and adhesion characteristics
are poor.

 Always use a drill with a rotation speed

adjustment, otherwise the rear bumper may
deform.

 Be careful when handling drills and other sharp

objects.

 To prevent scratching and over-drilling,

always wrap the drill bit with duct tape.

INSTALLATION OF OPTIONAL ON-OFF SWITCH FOR USE WHEN TOWING

 This procedure is not necessary if the [optional on-off switch for use when towing] is not installed.

Go to 9. CAUTIONS WHEN RE-INSTALLING.

Note

 Always use a drill with a rotation speed

adjustment, otherwise the rear trunk side trim
may deform.

 Be careful when handling drills and other sharp

objects.

 To prevent scratching and over-drilling,

always wrap the drill bit with duct tape.

CAUTION

 Be careful when handling drills and other sharp

objects.
If not handled properly, it could result in serious
injury.

■ Is available when the ignition is switched ON and shift lever is in the R position.

■ The sensor detects obstructions when the shift lever is in the R position.

・ Alarm (beeper) sound

■ The beeper operates (sounds) as follows while the system is operating.

* The closer the obstruction is approached the faster the continuous sound is emitted.

Malfunction symptom Inspection Action

Alarm sound (buzzer) does not activate even though
there is an obstruction around the sensor.

Is the ignition switched ON? Switch the ignition ON.
Is each part connected correctly?

(Each connector, reverse signal line,

ground terminal)

Connect each part correctly.

Is there a device generating ultrasonic
waves near the vehicle?

(Air compressor, high-pressure car

washer, impact wrench, or electric drill)

Take the device away from the
ultrasonic wave generation
source.

Is the shift lever in the R position? Shift the shift lever to the R

position.

Alarm sound (buzzer) activates even though there is
no obstruction around the sensor.

Is the ground detected?
* If beep sound stops after placing
cardboard on the ground, the ground
may be detected.

Install the sensor correctly.
