COOLING FAN SYSTEM (1ZZ±FE/3ZZ±FE)
ON±VEHICLE INSPECTION
HINT:
It is normal that the cooling fan sometime rotates when the ignition switc\
h is turned from ACC to ON.
1. CHECK COOLING FAN OPERATION WITH LOW TEMPERATURE (Below 94.5
C (202
F))
(a) Turn the ignition switch ON.
(b) Check that the cooling fan stops.
If not, check the cooling fan relay and engine coolant temperature sensor, and check if there is its connector
disconnection or circuit open between them.
(c) Disconnect the engine coolant temperature sensor connector.
(d) Check that the cooling fan rotates.
If not, check the fuses, cooling fan relay, ECM and cooling fan, and check for short in a circuit between the
cooling fan relay and the engine coolant temperature sensor.
(e) Reconnect the engine coolant temperature sensor connector.
2. CHECK COOLING FAN OPERATION WITH HIGH TEMPERATURE (Above 96
C (205
F))
(a) Start the engine, and raise coolant temperature to above 96
C (205
F).
HINT:
Coolant temperature is detected by the engine coolant temperature sensor\
on the water outlet.
(b) Check that the cooling fan rotates.
If not, replace the engine coolant temperature sensor.
3. INSPECT COOLING FAN
(a) Disconnect the cooling fan connector.
(b) Connect battery and ammeter to the connector.
(c) Check that the cooling fan rotates smoothly, and check the reading on the ammeter. Standard amperage: Approximately. 8 to 12 A at 20
C (68
F)
(d) Reconnect the cooling fan connector.

POWER DOOR LOCK CONTROL SYSTEM
ON±VEHICLE INSPECTION
1. DOOR LOCK FAIL±SAFE
(a) When a malfunction in the door control switch (manual switch, driver's door lock) has been detected,
door lock/unlock operation becomes disabled.
2. CHECK ELECTRICAL DOOR LOCK OPERATION
(a) Check the basic function. (1) Check that all doors lock when the door control switch (for manual operation\
) is turned to LOCKand all doors unlock when turned to UNLOCK.
(2) Check that all doors lock when the driver's door is locked from the outside using the key. Check that all doors unlock when the driver's door is unlocked from the outside using the key.
(b) Check the key lock±in prevention function.
NOTICE:
In order to prevent the key from being locked in, the inspection should be\
made with the driver side
door glass open. (1) Have the key inserted into the ignition key cylinder.
(2) With the driver side door open, check that all doors unlock immediately afte\
r the door lock knob
for the driver side door is turned to LOCK.
(3) With the driver side door open, check that all doors unlock immediately afte\
r the door control switch (for manual operation) is turned to LOCK.
(4) With the driver side door open, turn the driver side door lock knob to LOCK a\
nd hold it for 2 se- conds or more, and then close the driver side door. Then check that all doors unlock.
(c) Check the security function. (1) Close all doors with the driver side door glass open so that the door control\
switch can be oper-ated from outside the vehicle
(2) Pull out the key, open the driver side door and then close and lock the door without usi\
ng the key. Then, check that all doors do not unlock when the door control switch \
(for manual operation)
is turned to UNLOCK from outside the vehicle.
(3) Pull out the key, close and lock the driver side door by key operation. Under this condition, c\
heck
that all doors do not unlock when the door control switch (for manual opera\
tion) is turned to UN-
LOCK from outside the vehicle.
(4) Pull out the key, close the driver side door and lock the door by wireless door lock ope\
ration. Then, check that all doors do not unlock when the door control switch (for manual operation) is
turned to UNLOCK from outside the vehicle.
HINT:
Check that the security function is canceled under the following conditi\
ons.

3. FORCED DOOR LOCK CONTROL
(a) The forced door lock control prevents the vehicle from being tampered with. Immediately after a door\
is unlocked (alarm starts), the door is forced to lock by a forced doo\
r lock signal.
(1) Conditions that force the doors to lock:
When no key is in the ignition key cylinder and 0.4 seconds have elapsed aft\
er the previous out-
put of a forced door lock signal, the doors will be forced to lock if any o\
f the following conditions
is present.

The theft deterrent system is in the armed state of active arming mode.

All the doors are locked. Any door is unlocked.

Any door is unlocked.
HINT:
Only Europe:
Forced door lock control does not operate if any door is unlocked by key\
.
4. ALARM MEMORY FUNCTION
(a) If the alarm is set off (tampering is detected) while the theft deterrent system is set, the\
alarm memory function will record it. Whenever you cancel the theft deterrent system, the al\
arm memory function
causes the taillights to light up for 2 seconds in order to inform you t\
hat the alarm has been set off.
(1) Conditions of the alarm memory function that cause the taillights to lig\
ht up:
When the theft deterrent system has entered into the alarm sounding state (\
tampering has been
detected) even once, the taillights will light up for 2 seconds if any of the following conditions is
present.

Switched to the disarmed state from the armed state.
5. SECURITY INDICATOR OUTPUT
(a) The theft warning ECU outputs a signal to light up the security indicator, according to the state of the theft deterrent system. However, some of the actual lighting conditions of the security indicator are d\
if-
ferent from the outputs of the theft warning ECU.
