or LOCK position during Test Mode, the DTCs of the
signal check function will be erased.
(a) Turn the ignition switch off.
(b) Check that the steering wheel is in the straight-
ahead position and move the shift lever to the P
position (Automatic Transmission) or apply the
parking brake (Manual Transmission).
(c) Using SST, connect terminals TS and CG of the
DLC3.

Test Mode.
HINT:
If the ABS warning light does not blink, inspect the
TS and CG terminal circuit and the ABS warning
light circuit.
(f) Start the engine.
(g) Using SST, perform the speed sensor signal check
in Test Mode.
SST 09843-18040
(h) Drive the vehicle straight forward.
(i) Accelerate the vehicle to a speed of 28 mph (45 km/
h) or higher for several seconds and check that the
ABS warning light goes off.
HINT:
The signal check may not be completed if the
vehicle has its wheels spun.

(f) Check that the ABS warning light is blinking in the
Test Mode.
HINT:
If the ABS warning light does not blink, inspect the
TS and CG terminal circuit and the ABS warning
light circuit.
(g) Start the engine.
(h) Using the intelligent tester, perform the speed
sensor signal check in Test Mode.
(i) Drive the vehicle straight forward.
(j) Accelerate the vehicle to a speed of 28 mph (45 km/
h) or higher for several seconds and check that the
ABS warning light goes off.
HINT:
The signal check may not be completed if the
vehicle has its wheels spun.
(k) Stop the vehicle.
NOTICE:
• The speed sensor signal check may not be
completed if the steering wheel is turned or
the wheels are spun during the check.
• After the ABS warning light goes off and if
vehicle speed exceeds 50 mph (80 km/h), a
signal check code will be stored again.
Decelerate or stop the vehicle before the
speed reaches 50 mph (80 km/h).
• If the signal check has not been completed,
the ABS warning light blinks while driving
and the ABS system does not operate.
HINT:
When the signal check has been completed, the
ABS warning light goes off while driving and blinks
in the Test Mode pattern while stationary.
5. READ DTC
(a) Read the DTC(s) by following the tester screen.
HINT:
• Refer to the intelligent tester operator's manual
for further details.
• See the list of DTC.

3. PASSIVE ARMING MODE
HINT:
• Passive arming mode starts the alarm control after
the key is removed from the ignition key cylinder and
doors are closed.
• Passive arming mode can be switched ON/OFF by
the specified method.
• The alarm is initially set (when shipped from factory)
to active arming mode (not passive arming mode).
• During passive arming mode, the theft deterrent
system goes into the armed state even if the doors
are not locked.
• Detecting that the doors are unlocked does not set off
the alarm during passive arming mode.
• A forced door lock signal is not output during passive
arming mode (see FORCED DOOR LOCK
CONTROL).
• Although the theft deterrent system detects that the
doors are opened during passive arming mode, the
alarm will not go off immediately because an entry
delay time is set.
• If any of the following conditions is met during passive
arming mode, the theft deterrent system will switch to
active arming mode.
– With all doors and engine hood closed, lock all
doors by key operation.
– With all doors and engine hood closed, lock all
doors by wireless operation.
– With any door or the engine hood open, lock all
doors and close all doors and engine hood.
• This system activates as described in the diagram
below when one of items for each condition is met.
Condition (6)1. Unlock any door by wireless operation.
2. Unlock any door by key operation.
3. Insert key into ignition key cylinder and turn ignition switch from OFF to ON.
Condition (7) 1. After approx. 60 sec., alarm stops and system returns to armed state. Condition Item

THEFT DETERRENT – THEFT DETERRENT SYSTEMTD–7
TDHINT:
*1: When any door is opened while all the doors are
closed during passive arming mode, the entry delay
time starts. If the switch condition (armed state

disarmed state (1) or (2)) is met during the entry
delay time, the theft deterrent system will return to
disarmed state (1) or (2). However, if the switch
condition for disarmed state (1) or (2) is not met, the
theft deterrent system will recognize it as a theft and
set off the alarm.
Entry delay time of 0, 14 or 30 sec. can be selected
by the customizing function.
4. 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 door lock signal.
(1) Conditions that force the doors to lock:
No key is in the ignition key cylinder and both of
the following conditions are met.
• The theft deterrent system is in the alarm
sounding state of active arming mode.
• Any door is unlocked.
Condition (3)1. Unlock all door by wireless operation.
2. Insert key into ignition key cylinder.
3. Reconnect battery.
4. Turn ignition switch from OFF to ON.
5. Unlock any door by key operation.
Condition (4) 1. With all doors and engine hood closed, allow approx. 30 sec. to elapse.
Condition (5) 1. Open any door or the engine hood.
Condition (6)1. Open any door and allow entry delay time
*1 to elapse.
2. Open engine hood.
3. Reconnect battery.
4. Directly connect ignition switch without key (or turn ignition switch ON without key).
Condition (7)1. Unlock all door by wireless operation.
2. Unlock all door by key operation.
3. Insert key into ignition key cylinder and turn ignition switch from OFF to ON.
Condition (8) 1. After approx. 60 sec., alarm stops and system returns to armed state. Condition Item

PRECAUTION
1. INITIALIZATION
NOTICE:
• Perform RESET MEMORY (AT initialization) when
replacing the automatic transaxle assembly, engine
assembly or ECM (See page AX-16).
• Perform REGISTRATION (VIN registration) when
replacing the ECM (See page ES-15).
HINT:
Initialization cannot be completed by only removing the
battery.
2. FOR USING INTELLIGENT TESTER
CAUTION:
Observe the following items for safety reasons:
• Before using the tester, read the instruction
manual.
• Prevent the tester cable from being caught on the
pedals, shift lever and steering wheel when
driving with the tester connected to the vehicle.
• When driving the vehicle for testing purposes
using the tester, two persons are required. One is
for driving the vehicle, and the other operates the
tester.
3. FOR USING BATTERY DURING INSPECTION
(a) While using the battery during inspection, do not
bring the positive and negative tester probes too
close to each other as a short circuit may occur.
4. COOLING FAN SYSTEM
NOTICE:
• When the ignition switch is turned off and the engine
temperature is high, the cooling fans may operate for
approximately 3 minutes.
• After turning the ignition switch off, keep hands and
objects away from the fans when they are operating.
HINT:
If all of the following are met for a certain period of time during
a few minute period immediately before the engine is
stopped, the electric fans will continue to operate for 3
minutes after the engine is stopped. This is performed to
ensure restartability and stabilize idle speed.
– The intelligent tester indicates a very high coolant
temperature.
– The intelligent tester indicates a high outside air
temperature.
– The vehicle has been driven under high load (driving on an
uphill or equivalent).
The following sensors are used for this control:
– Coolant temperature sensor
– Outside air temperature sensor
–MAF sensor
– Vehicle speed sensors

BASIC INSPECTION
When a malfunction is not confirmed by the DTC check,
troubleshooting should be carried out in all circuits
considered to be possible causes of the problem. In many
cases, by carrying out the basic engine check shown in the
following flowchart, the location of the problem can be found
quickly and efficiently. Therefore, using this check is essential
when engine troubleshooting.
NOTICE:
Carry out this check with the engine stopped and ignition
switch off.
