2023 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 in spection 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.
4. Check that no small animals enter the
engine compartment.
5. Check that the hood and trunk are fully
closed.
6. Check the adjustment of the seat.
7. Check the adjustment of the inside
and outside mirrors.
8. Fasten your seatbelt. Check that your
passengers have fastened their seatbelts.

Starting and Stopping Engine
230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
(MT models) or the brake pedal (AT
models) to switch the power to “OFF”. - If the light had illuminated, try to
start the engine again.
- If the light had been off, press the
push-button ignition switch while
depressing the clutch pedal (MT
models) or the brake pedal (AT
models) more forcefully.
 The engine start procedures may
not function depending on the radio
wave conditions around the vehicle. In
such a case, refer to "Starting Engine"
 P326.
 If the vehicle battery is discharged,
the steering cannot be unlocked.
Charge the battery.
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

ABS (Anti-Lock Brake System)
245
Starting and Operating7
■Disc Brake Pad Wear
Wa rning IndicatorsThe disc brake pad wear warning indica-
tors on the disc brakes give a warning
noise when the brake pads are worn.
If a squeaking or scraping noise is heard
from the disc brakes while braking, imme-
diately have your vehicle inspected by the
nearest SUBARU dealer.
7-11. ABS (Anti-Lock BrakeSystem)
The 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 f eel a slight vibration
in the brake pedal. This is normal when
the ABS operates.■ ABS Self-CheckYou 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 LightRefer to "ABS Warning Light" P140.
700040
WARNING
Always use the utmost care in driv-
ing – overconfidence because you
are driving with an ABS equipped
vehicle could easily lead to a seri-
ous accident.
CAUTION
 The ABS does not always
decrease stopping distance. You
should always maintain a safe
following distance from other
vehicles. When driving on badly surfaced
roads, gravel roads, icy road, or
over newly fallen snow, stopping
distances may be longer for a
vehicle with the ABS than one
without. When driving under
these conditions, therefore,
reduce your speed and leave
ample distance from other vehi-
cles.
 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.

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 CodesEvery tire pressure warning valve and
transmitter has a unique ID code. In addi-
tion to the set of tire pressure monitoring
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 monitoring
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 set1. Park the vehicle in a safe place and
turn the ignition swit ch to the “ON” posi-
tion.
2. Press the TPMS set switch 3 times
within 3 seconds.

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.
WARNING
 Never leave unattended children
or pets in the vehicle. They could
accidentally injure themselves or
others through inadvertent oper-
ation of the vehicle. Also, on hot
or sunny days, the temperature in
a closed vehicle could quickly
become high enough to cause
severe or possibly fatal injuries to
people. Do not park the vehicle over flam-
mable materials such as dry
grass, waste paper or rags, as
they may burn easily if they come
near hot engine or exhaust
system parts. Be sure to stop the engine if you
take a nap in the vehicle. If engine
exhaust gas enters the passenger
compartment, occupants in the
vehicle could die from carbon
monoxide (CO) contained in the
exhaust gas.
