1. DIAGNOSIS SYSTEM
(a) Description

When troubleshooting On-Board Diagnostic (OBD
ll) vehicles, the vehicle must be connected to the
OBD ll scan tool (in compliance with SAE J1978) or
the hand-held tester. Various data output from the
vehicle's ECM can then be read.

OBD ll regulations require that the vehicle's on-
board computer illuminates the Malfunction Indica-
tor Light (MIL) on the instrument panel when the
computer detects a malfunction in: 1) the emission
control system/components, or 2) the powertrain
control components (which affect vehicle emis-
sions), or 3) the computer. In addition, the applica-
ble Diagnostic Trouble Codes (DTCs) prescribed by
SAE J2012 are recorded in the ECM memory
(See page DI-36).
If the malfunction does not reoccur in 3 consecutive trips, the
MIL goes off automatically but the DTCs remain recorded in the
ECM memory.

To check the DTC, connect the hand-held tester or
OBD II scan tool to the Data Link Connector 3
(DLC3) of the vehicle. The hand-held tester or OBD
II scan tool also enables you to erase the DTC and
check the freeze frame data and various forms of
engine data (See the instruction manual for the
OBD ll scan tool or the hand-held tester). The DTC
includes SAE controlled codes and manufacturer
controlled codes. SAE controlled codes must be set
according to the SAE, while manufacturer con-
trolled codes can be set by a manufacturer with cer-
tain restrictions (See the DTC chart on page
DI-36).

(a) Preconditions
The monitor will not run unless:

MIL is OFF

Fuel level is approximately 1/2 to 3/4

Altitude is 7,800 feet (2,400 m) or less*

Engine Coolant Temperature (ECT) is between 4.4°C and 35°C (40°F and 95°F)

Intake Air Temperature (IAT) is between 4.4°C and 35°C (40°F and 95°F)

Cold Soak Procedure has been completed

Before starting the engine, the difference between ECT and IAT must be less than 7°C (13°F)
HINT:
Examples:

Scenario 1
ECT = 24°C (75°F)
IAT = 16°C (60°F)
Difference between ECT and IAT is 8°C (15°F)
" The monitor will not run because difference between ECT and IAT is greater than 7°C (13°F)

Scenario 2
ECT = 21°C (70°F)
IAT = 20°C (68°F)
Difference between ECT and IAT is 1°C (2°F)
" The monitor will run because difference between ECT and IAT is less than 7°C (13°F)
The readiness test can be completed in cold ambient conditions (less than 40°F / 4.4°C) and/or at
high altitudes (more than 7,800 feet / 2,400 m) if the drive pattern is repeated a second time after cycl-
ing the ignition off.
(b) Drive Pattern
(1) Connect the OBD II scan tool to DLC3 to check monitor status and preconditions (refer to ºaº).
(2) Release pressure in fuel tank by removing the fuel tank cap and then reinstalling it.
(3) Start the engine and allow it to idle until ECT becomes 75°C (167°F) or higher.
(4) Run the engine at 3,000 rpm for about 10 seconds.
(5) Allow the engine to idle with the A/C ON (to create slight load) for 15 to 50 minutes.
NOTICE:
If the vehicle is not equipped with A/C put a slight load on the engine by doing the following :

Securely set the parking brake.

Block the drive wheels with wheel chocks.

Allow the vehicle to idle in drive for 15 to 50 minutes.

1. DIAGNOSIS SYSTEM
(a) Description
ECM controls the function of immobiliser on this vehicle.
Data of the immobiliser or DTC can be read from DLC3 of
the vehicle. When a trouble occurs on immobiliser, MIL
does not light up but DTC inspection is performed.
Therefore when there seems to be a trouble on immobilis-
er, use hand-held tester or SST to check and trouble-
shoot it.
(b) Inspect the DLC3.
The vehicle's ECM uses ISO 9141-2 for communication.
The terminal arrangement of DLC3 complies with
SAEJ1962 and matches the ISO 9141-2 format.

Line) - 5 (Signal ground)During communicationPulse generation
4 (Chassis Ground) - BodyAlways1 W or less
5 (Signal Ground) - BodyAlways1 W or less
16 (B+) - BodyAlways9 - 14 V
HINT:
If your display shows ºUNABLE TO CONNECT TO VEHICLEº
when you have connected the cable of hand-held tester to
DLC3, turned the ignition switch ON and operated the hand-
held tester, there is a problem on the vehicle side or tool side.

If communication is normal when the tool is connected to
another vehicle, inspect DLC3 on the original vehicle.

If communication is still not possible when the tool is con-
nected to another vehicle, the problem is probably in the
tool itself, so consult the Service Department listed in the
tool's instruction manual.

PRE-CHECK
1. OUTLINE OF THEFT DETERRENT SYSTEM
The security has an ºAlarm Controlº and the control consists of
2 modes.
Active mode
This mode begins ºAlarm Controlº as the user locks
the vehicle by intention (See the reference step 2).
Passive mode
This mode begins ºAlarm Controlº even if the user
forgets locking the vehicle (See the reference step
5). (This mode begins ºAlarm Controlº when the
user closed all doors and the engine hood.)
HINT:
ºAlarm Controlº refers to the function that detects intru-
sion into the vehicle and sounds an alarm.
Even when the ºAlarm Controlº operates in the passive
mode, it works as in the active mode if a condition to begin
the active mode is met.
2. ACTIVE ARMING MODE
There are 4 modes in active mode.
(1) Disarmed state
The alarm system is not set (theft detection is
impossible), and the alarm does not sound.
The system does not detect any theft.
(2) Arming preparation (for 30 seconds)
The waiting period when the alarm set re-
quirements are met to when the system is ac-
tually set.
(3) Armed state
The state the alarm is set (operation is possible).
The system can detect theft.
(4) Alarm sounding:
The system detects theft and informs using sounds
and lights.
The state of waiting to switch to armed state
again to have alarming interval after finishing
alarming time.
Perform forced door lock when the door is un-
locked.
