Cooling Fan Circuit
DESCRIPTION
rd
ca
The ECM calculates an appropriate cooling fan speed based on the engine coolant temperature, air conditioning
switch condition, refrigerant pressure, engine speed, and vehicle speed and sends the signals to the cooling fan
ECU to regulate the cooling fan. The cooling fan ECU controls the cooling fan speed based on the duty ratio
signal sent from the ECM. By basing its control on the operating conditions, the ECM can control the fan speed
optimally using the cooling fan ECU, achieving both high cooling performance and quietness. The cooling fan
speed is determined based on the engine coolant temperature, air conditioner operating conditions, engine
speed, and vehicle speed.

SMART KEY SYSTEM (FOR ENTRY FUNCTION)
PRECAUTION
PRECAUTION
rd
ca
1. PRECAUTIONS WHEN USING TECHSTREAM
a. When troubleshooting the smart key system using the Techstream with the engine switch off,
connect the Techstream to the vehicle and repeat turning any of the courtesy light switches on and
off until communication between the Techstream and the vehicle begins (the interval between ON
and OFF should be less than 1.5 seconds).
b. After DTCs are all cleared, check if the trouble occurs again 6 seconds after the engine switch is
turned on (IG).
2. PRECAUTIONS FOR EACH FUNCTION
a. Precautions for the key:
m
co
n.
g
ia
The key is a precision instrument. Be sure to observe the following:
1. Do not drop or strike the key.
2. Do not keep the key in a high temperature area for a long time.
3. Do not use an ultrasonic washing machine to clean the key.
4. Keep the key away from magnets or magnetized items during use.
5. Do not attach any stickers to the key.
6. If a key is lost, delete all registered key ID codes and then reregister the remaining keys.
b. Precautions for the entry unlock function:
1. As the sensor is built into the backside of the outside door handle, the user must touch the
backside of the handle when performing the unlock function.
2. If the backside of the handle is touched with gloved hands, the response of the door may be
delayed.
3. During the entry unlock operation, if the door handle is pulled before the door unlocks, the
unlock function cannot be completed. Confirm that the door has been unlocked before
pulling the door handle to open the door.
4. Make sure that the doors are unlocked when touching the touch sensor on the outside door
handle while the key is being carried.
If the doors cannot be unlocked, the certification ECU (smart key ECU assembly) orders the
main body ECU (instrument panel junction block) to perform the door unlock operation 4
times at intervals of 0.75 seconds.
At this time, the door may not be unlocked because the handle is being pulled due to some
2013 Toyota Corolla
2013 ACCESSORIES & EQUIPMENT Smart Key System (Diagnostics & Symptom Tests) - Corolla
mechanical reasons.
Be sure to return the door handle to its original position.
If the door cannot be opened by pulling the handle, perform the entry unlock operation again.
5. If the key is too close to the electrical key oscillator on the outside of the vehicle, the door
may not be unlocked because the key cannot react to the strong wave output from the
transmitter.
6. If the key is within the vehicle exterior detection area, the door can be unlocked even when a
person other than the person carrying the key holds the door handle.
However, the doors other than the door that the codes match will not be unlocked.
rd
ca
(If the key is within the driver side door's detection area outside the vehicle, the doors will be
unlocked when the person carrying the key holds the driver side door handle. However, if
any door handle other than that of the driver side door is held, the doors will not be
unlocked).
m
co
n.
g
ia
7. If a door is not opened after the door unlock operation, the doors automatically lock after
approximately 60 seconds.
8. If a large amount of water is applied to the door handle due to a car wash or heavy rain, the
key being within the vehicle exterior detection area may cause the doors to be unlocked.
However, the doors will be locked again after approximately 60 seconds if a door is not
opened.
9. If the key of the smart key system is used while it is being carried with the key of another
smart key system, the time before the entry unlock operation will become longer than usual.
This is not a malfunction.
c. Precautions for the entry lock function:
1. When performing the entry lock operation, firmly press the lock switch on the outside door
handle.
If the lock switch is pressed too quickly or lightly, the entry lock may not operate.
2. Signals output from the indoor electrical key antenna may leak through the window. Also, if
the key is too close to a door electrical key oscillator, the electrical key oscillator output
signals are too strong and the key cannot respond. As a result, when the key is near the
vehicle (window, door handle), the entry lock function may not operate. Also, the key
reminder warning buzzer may sound and the entry unlock operation may stop functioning. In
this situation, move the key away from the vehicle (window, door handle), perform the entry
lock operation and perform the entry unlock operation.
3. Do not touch the lock switch while opening or closing a door.
If the lock switch is pressed when opening or closing a door while the key is being carried,
2013 Toyota Corolla
2013 ACCESSORIES & EQUIPMENT Smart Key System (Diagnostics & Symptom Tests) - Corolla
the door ajar warning buzzer sounds (beeps outside the vehicle for 10 seconds).
rd
ca
4. If the key is on the instrument panel, rear package tray, floor, or in the glove box, the key
reminder function may not operate and the key may be locked in the vehicle. Always carry
the key.
5. If the key is outside the vehicle but is very close to a window or door handle (the ECU
determines that the key is inside the vehicle) and the transmitter or mechanical key is used to
lock the doors (entry lock is not used), entry unlock will not operate. To unlock the doors,
perform a wireless door unlock operation. The entry lock function operates in this way to
prevent the user from unintentionally unlocking the doors from outside the vehicle. For
example, when a user operates the wireless door lock operation from inside the vehicle, radio
waves from a door electrical key oscillator may leak into the vehicle interior and the doors
may unlock.
6. To allow the user enough time to check if the doors are locked after performing a door lock
operation (entry lock function or wireless door lock operation), the entry unlock function will
not be permitted for 3 seconds after the door lock operation.
d. Precautions for luggage compartment door entry function:
m
co
Near the center of the bumper
 Too close to the ground or in a high place
e. Precautions for the function to prevent key confinement in the luggage compartment:
1. Do not place the key in the luggage compartment.

n.
g
ia
Even if the key is within the outside electrical key oscillator (luggage compartment) detection area,
the luggage compartment door cannot be opened if the key is in the following areas:
If the luggage compartment door is closed with the key in it when all the doors are locked,
the alarm to indicate key confinement will operate (beeping sound for 2 seconds outside of
the vehicle). However, the alarm may not operate for some reason relating to the key location
(near the spare tire or the side of the luggage compartment), the key condition (covered with
metal or near metal), or ambient radio waves.
2. If the luggage compartment door is closed with the key in it when any of the doors is
unlocked or open, the key confinement prevention function will not operate. In this case, use
the luggage compartment opener in the cabin to open the luggage compartment door and take
out the key.
3. The alarm may erroneously operate in the following conditions. If you can confirm that you
are carrying the key or that the key is in the cabin, there is no problem. The entry luggage
compartment open function may not operate if the alarm erroneously operates. In this case,
use the luggage compartment opener in the cabin or perform a wireless operation to open the
luggage compartment door.
- The key is brought into the cabin after the luggage compartment door is opened, and then
the luggage compartment door is closed.
- The luggage compartment door is closed by the person who is carrying the key.
2013 Toyota Corolla
2013 ACCESSORIES & EQUIPMENT Smart Key System (Diagnostics & Symptom Tests) - Corolla
rd
ca
4. If the alarm operates when the luggage compartment door is closed with all the doors locked,
the key is in the cabin or luggage compartment. Check the cabin and luggage compartment to
find the key.
5. If the luggage compartment door is closed with the key in it when all the doors are locked,
the alarm will sound and the luggage compartment door can be opened. This may increase
the risk of the vehicle being stolen.
6. Do not open or close the luggage compartment door after all the doors are locked if you want
to keep the spare keys in the cabin. As a result, the alarm may sound and the luggage
compartment door can be opened. This may increase the risk of the vehicle being stolen.
f. Precautions for the battery built into the key and the vehicle battery:
1. The key is constantly checking for signals from the vehicle, which requires power from the
key's built-in battery. The life of the battery is approximately 1 to 2 years depending on the
usage conditions. Be sure to replace the battery when its power is low. When replacing the
battery, do not touch the inner circuit board or other inner parts.
2. The key is constantly checking for signals from the vehicle using battery power to determine
whether the key is being used or not. Even if the user is carrying 2 keys and only 1 key is
used, both keys will consume battery power.
3. The key receives radio waves at approximately 314 MHz. If the key continuously receives
strong, identical frequency waves, the key's battery may be drained. Store the key at least 1 m
(3.3 ft.) away from TVs, personal computers, or other electrical products.
4. When a door is being locked, the vehicle battery is used to transmit radio waves. The battery
may be dead if the vehicle remains stopped for a long time. If the vehicle is not used for a
long time, remove the battery from the vehicle or cancel the smart key system.
5. When a door is being locked with the key in the detection area of a door electrical key
oscillator, the battery is used for regular communication between the key and vehicle. If the
vehicle is not used, keep the key away from the vehicle (more than 2 m (6.6 ft.)).
6. After disconnecting and reconnecting the battery cable, the entry unlock function may not
operate. If this occurs, perform a wireless door unlock and lock operation.
g. Precautions for the entry unlock mode switching function:
1. Use the entry unlock mode switching function within a 1 m (3.3 ft.) area around the vehicle.
2. The entry unlock mode switching function cannot be used within 5 seconds of the previous
mode change. Wait 5 seconds or more before performing a mode change.

4. CONSTRUCTION AND OPERATION
a. Key
The key consists of a mechanical key, a transmitter for the wireless door lock control, and a
transceiver for the smart key system.


The transceiver for the smart key system receives signals from the oscillators and sends the
ID code to the tuner.
The transmitter for the wireless door lock control has a LOCK switch, UNLOCK switch,
LUGGAGE COMPARTMENT switch.
2013 Toyota Corolla
2013 ACCESSORIES & EQUIPMENT Smart Key System (Diagnostics & Symptom Tests) - Corolla

b. Electrical key oscillator (door electrical key oscillators, indoor electrical key oscillators (front, rear
and luggage compartment) and outside electrical key oscillator (luggage compartment))
Each electrical key oscillator transmits the request signal received from the certification ECU
(smart key ECU assembly), and forms a key detection area to detect the presence of a key. The
detection area formed by the door electrical key oscillator and outside electrical key oscillator
(luggage compartment) is approximately 0.7 to 1.0 m (2.3 to 3.3 ft.) from the outside handle of the
door or the center of the rear bumper.
The detection area of the door electrical key oscillator is formed by transmitting a request
signal every 0.25 seconds while the engine switch is off and each door is locked. In this way,
the oscillator detects the proximity of a key. During entry lock, the detection area is formed
with the lock switch on.
 The detection area of the outside electrical key oscillator (luggage compartment) is formed
when the power luggage door open switch is on.
 The detection area of the indoor electrical key oscillator (front and rear) is formed when the
driver door is opened or closed, during start ignition, when a warning is activated, or the lock
switch is on.
 The detection area of the indoor electrical key oscillator (luggage compartment) is formed
when the luggage compartment door is closed, or the luggage compartment opener outer
switch is pressed.

2013 ACCESSORIES & EQUIPMENT Smart Key System (Diagnostics & Symptom Tests) - Corolla
rd
ca
c. In unlock standby mode, the antenna built into the outside handle starts sensing. If the outside
handle is held (the back side of the handle is touched), the door unlock operation will be performed.
At this time, the hazard warning light blinks twice and the wireless door lock buzzer sounds twice.
d. If any of the doors are not opened after a door unlock operation, all doors will automatically lock
after 60 seconds.
8. ENTRY LOCK FUNCTION
a. After leaving the vehicle carrying the key, push the lock switch on the outside handle when all the
doors are closed.
b. The certification ECU (smart key ECU assembly) determines whether the key is located inside or
outside the cabin based on the information from a door electrical key oscillator and indoor electrical
key oscillator. Then matching of the ID codes is performed.
c. When the matching result shows that the ID codes of the key and indoor antenna do not match and
the ID codes of the key and door electrical key oscillator match, the door lock function will operate.
At this time, the hazard warning lights blink once and the wireless door lock buzzer sounds once.
d. If the key is located inside the cabin, the door lock function will not operate and the alarm buzzer
(beep sound) will sound for 2 seconds.
9. ENTRY LUGGAGE COMPARTMENT OPEN FUNCTION
g

10. KEY LOCK-IN PREVENTION FUNCTION
a. If you attempt to lock the door through keyless operation (move the lock knob to the lock position
and then close the door) with the key in the cabin, the system determines that the key is located in
the cabin and unlocks the door.
b. If the luggage compartment is closed with the key in it, the alarm will sound and the luggage
compartment can be opened only when all the doors are locked in order to prevent key confinement
in the vehicle.

a. Vehicle Battery Saving Function
In the smart key system, signals are emitted outside the vehicle at a prescribed interval (0.25
seconds) when the doors are locked. Therefore, the vehicle battery could be drained if the vehicle
remains parked for a long time. For this reason, the controls listed below are carried out:

 A user carries the key and pushes a lock switch on an outside door handle.
 A door is locked or unlocked by the mechanical key.
b. Key Battery and Vehicle Battery Saving Function

In the smart key system, if the key is constantly located within the vehicle exterior detection area of
the doors, the system maintains periodic communication with the key. Therefore, if the vehicle
remains parked in that state for a long time, the key battery and the vehicle battery could be
drained. For this reason, if this state continues longer than 10 minutes, the smart key system
automatically becomes deactivated.

1. DATA LIST
HINT:
Using the Techstream to read the Data List allows the values or states of switches, sensors, actuators and
other items to be read without removing any parts. This non-intrusive inspection can be very useful
because intermittent conditions or signals may be discovered before parts or wiring is disturbed. Reading
the Data List information early in troubleshooting is one way to save diagnostic time.
NOTE:
In the table below, the values listed under "Normal Condition" are
reference values. Do not depend solely on these reference values when
deciding whether a part is faulty or not.

2. ACTIVE TEST
HINT:
Using the Techstream to perform Active Tests allows relays, VSVs, actuators and other items to be
operated without removing any parts. This non-intrusive functional inspection can be very useful because
intermittent operation may be discovered before parts or wiring is disturbed. Performing Active Tests
early in troubleshooting is one way to save diagnostic time. Data List information can be displayed while
performing Active Tests.
a. Connect the Techstream to the DLC3.

MALFUNCTION
DESCRIPTION
The skid control ECU converts these signals into 4-pulse signals and sends them to the combination meter.
After this signal is converted into a more precise rectangular waveform by the waveform shaping circuit inside
the combination meter, it is then transmitted to the main body ECU (instrument panel junction block). The main
body ECU (instrument panel junction block) determines the vehicle speed based on the frequency of these pulse
signals.
The main body ECU (instrument panel junction block) and the combination meter are connected by a cable and
the CAN. DTC B2282 is output when the cable information and CAN information are inconsistent.

DESCRIPTION

ia
Engine does not Start
1. ENGINE START SYSTEM FUNCTION
a. If the engine switch is pressed with the shift lever is in P or N and the brake pedal depressed, the
main body ECU (instrument panel junction block) determines that it is an engine start request.
b. The certification ECU (smart key ECU assembly) and other ECUs perform key verification via the
LIN communication line.
c. The main body ECU (instrument panel junction block) activates the ACC relay.
d. The main body ECU (instrument panel junction block) activates the IG1 and IG2 relays.
e. The certification ECU (smart key ECU assembly) outputs a steering UNLOCK signal. The signal is
sent to the main body ECU (instrument panel junction block) via the steering lock ECU.
f. The main body ECU (instrument panel junction block) sends an engine start request signal to the
ECM.
g. The ECM sends an ACC cut request signal to the main body ECU (instrument panel junction
block).
h. The ECM and main body ECU (instrument panel junction block) activate the ST relay.
i. The main body ECU (instrument panel junction block) deactivates the ACC relay until the main
body ECU (instrument panel junction block) detects an engine start.
j. When engine revolution speed reaches 1200 rpm, the ECM determines that the engine has been
started.
The ECM stops sending an ACC cut request signal to the main body ECU.
2013 Toyota Corolla
2013 ACCESSORIES & EQUIPMENT Smart Key System (For Start Function) (Diagnostics & Symptom Tests) - Corolla
The main body ECU (instrument panel junction block) reactivates the ACC relay and turns off the
engine switch indicator light, when engine revolution speed reaches 800 rpm.
