2022 SUBARU BRZ check engine light

Preparing to Drive
228have implemented emission inspection of
the OBDII system.
The inspection of the OBDII system
consists of a visual operational check of
the “ CHECK ENGINE ” warning light/
malfunction indicator light (MIL) and an
examination of the OBDII system with an
electronic scan tool.
 A vehicle passes
the OBDII system
inspection if proper operation of the
“ CHECK ENGINE ” warning light is
observed, there are no stored diagnostic
trouble codes, and the OBDII readiness
monitors are all complete.
 A vehicle fails
the OBDII inspection if
the “ CHECK ENGINE ” warning light is not
properly operating (light is illuminated or is
not working due to a burned out bulb) or
there is one or more diagnostic trouble
codes stored in the vehicle’s computer.
 A state emission inspection may reject
(not pass or fail) a vehicle if the number of
OBDII system readiness monitors “ NOT
READY ” is greater than one. If the
vehicle’s battery has been recently
replaced or disconnected, the OBDII
system inspection may indicate that the
vehicle is not ready for the emission test.
Under this condition, the vehicle driver
should be instructed to drive his/her
vehicle for a few days to reset the readi-
ness monitors and return for an emission
re-inspection. 
Owners of rejected or failing vehicles
should contact their SUBARU Dealer for
service.
7-3. Preparing to DriveYou should perform the following checks
and adjustments every day before you
start driving.
1. Check that all windows, mirrors, and
lights are clean and unobstructed.
2. Check the appearance and condition
of the tires. Also check tires for proper
inflation.
3. Look under the vehicle for any sign of
leaks.

Starting and Stopping Engine
230When the warm-up is completed, the
engine speed lowers automatically.
On rare occasions, it may be difficult
to start the engine depending on the
fuel and the usage condition (repeated
driving of a distance in which the
engine has not warmed up suffi-
ciently). In such a case, it is recom-
mended that you change to a different
brand of fuel.
 On rare occasions, transient
knocking may be heard from the
engine when the accelerator is oper-
ated rapidly such as a rapid start-up
and a rapid acceleration. This is not a
malfunction.
 The engine starts more easily when
the headlights, air conditioner and rear
window defogger are turned off.■
Starting Engine NOTE

When pressing the push-button
ignition switch while depressing the
clutch pedal (MT models) or the brake
pedal (AT models): - The engine starter operates for a
maximum of 10 seconds and after
starting the engine, the starter stops
automatically.
- The engine can be started
regardless of the power status.
 If the engine does not start, check
the security indicator light. Then press
the push-button ignition switch
without depressing the clutch pedal
WARNING
 There are some general precau-
tions when starting the engine.
Carefully read the precautions
described in "General Precau-
tions When Starting Engine"

P229.
If the steering lock cannot be
released after the engine has
started, never drive the vehicle.
The steering is still locked, and it
may result in an accident.
CAUTION
If a system malfunction warning
message is displayed on the
combination meter, there may be
a malfunction with the vehicle.
Contact a SUBARU dealer imme-
diately.If a steering lock warning
message is displayed on the
combination me ter after the
engine has started, it means that
the steering is still locked. While
moving the steering wheel right
and left, depress the brake pedal,
and press the push-button igni-
tion switch.
 Do not continue pressing the
push-button ignition switch for
more than 10 seconds. Doing so
could cause a malfunction. If the
engine does not start, stop
pressing the push-button ignition
switch. Instead, press the push-
button ignition switch without
depressing the clutch pedal (MT
models) or the brake pedal (AT
models) to switch the power
status to “OFF”. Wait 10 seconds,
and then press the push-button
ignition switch to start the
engine.

Electronic Brake Force Distribution (EBD) System
246The ABS prevents the lock-up of wheels
which may occur during sudden braking or
braking on slippery road surfaces. This
helps prevent the loss of steering control
and directional stability caused by wheel
lock-up.
When the ABS is operating, you may hear
a chattering noise or feel a slight vibration
in the brake pedal. This is normal when
the ABS operates.■
ABS Self-Check
You may feel a slight shock in the brake
pedal and hear the operating noise of the
ABS from the engine compartment just
after the vehicle is started. This is caused
by an automatic functional test of the ABS
being carried out and does not indicate
any abnormal condition.■
ABS Warning Light
Refer to "ABS Warning Light" P140.
7-12. Electronic Brake Force Distribution (EBD) SystemThe EBD system maximizes the effective-
ness of the brakes by allowing the rear
brakes to supply a greater proportion of
the braking force. It functions by adjusting
the distribution of braking force to the rear
wheels in accordance with the vehicle’s
loading condition and speed.
The EBD system is an integral part of the
ABS and uses some of the ABS compo-
nents to perform its function of optimizing
the distribution of braking force. If any of
the ABS components used by the EBD
function fails, the EBD system also stops
working.
When the EBD system is operating, you
may hear a chattering noise or feel a slight
vibration in the brake pedal. This is normal
and does not indicate a malfunction.
■
EBD System Malfunctions
If a malfunction occurs in the EBD system,
the system stops working and the
following warning lights illuminate simulta-
neously.
 Brake system warning light
 ABS warning light
 Vehicle Stability Control (VSC)
warning light
If the both warning light remains on even
though the parking brake is released, the
brake fluid level may be low or there could
be a problem with the EBD system. Park
the vehicle in a safe place immediately
and contact an SUBARU dealer.
 When you feel the ABS operating,
you should maintain constant
brake pedal pressure. Do not
pump the brake pedal since doing
so may defeat the operation of the
ABS.

specified level when the tires are cold, and
conduct initialization again.
■
When Initialization of the Tire
Pressure Monitoring System
has Failed
Initialization can be completed in a few
minutes. However, in the following case,
the settings have not been recorded and
the system will not operate properly. If
repeated attempts to record tire inflation
pressure settings are unsuccessful, have
the vehicle checked at your SUBARU
dealer.
 When operating the TPMS set switch,
low tire pressure warning light does not
blink 3 times.
 After carrying out the initialization
procedure, the low tire pressure warning
light blinks for 1 minute then stays on after
driving for 20 minutes.
■
Registering ID Codes
Every tire pressure warning valve and
transmitter has a unique ID code. In addi-
tion to the set of tire pressure warning
system sensor ID code s initially registered
to the vehicle, a second set of ID codes
can be registered.
A second set of tire pressure warning
system sensor ID codes can be registered
at your SUBARU dealer. When 2 sets of
ID codes have been registered, either ID
code set can be selected.■
Changing the ID code set
1. Park the vehicle in a safe place and
turn the ignition switch to the “ON” posi-
tion.
2. Press the TPMS set switch 3 times
within 3 seconds.
3. The low tire pressure warning light will
illuminate for 3 seconds and then blink 3
times.
4. The low tire pressure warning light will
blink for 1 minute and then illuminate.
5. When the ID code change has
completed, the tire pressure monitoring
light will turn off.
Check that tire pressures are displayed on
the TPMS screen.
WARNING
Do not operate the TPMS set switch
without first adjusting the tire infla-
tion pressure to the specified level.
Otherwise, the low tire pressure
warning light may not come on even
if the tire inflation pressure is low,
or it may come on when the tire
inflation pressure is actually nor-
mal.
