(g) CURTAIN SHIELD AIRBAG ASSEMBLY
(1) Always store a removed or new curtain shield air-
bag assembly in a clear plastic bag, and keep it in
a safe place.
NOTICE:
Protection bag is not reused.
CAUTION:
Never disassemble the curtain shield airbag assembly
(2) Never measure the resistance of the airbag squib
(This may cause the airbag to deploy, which is very
dangerous.).
(3) Grease should not be attached to the curtain shield
airbag assembly and the surface should not be
cleaned with any kind of detergents.
(4) Store the airbag assembly where the ambient tem-
perature remains below 93°C (200°F), without high
humidity and away from electrical noise.
(5) When using electric welding, first disconnect the air-
bag connector (yellow color and 2 pins) into the
instrument panel before starting work.
(6) When disposing of a vehicle or the curtain shield air-
bag assembly alone, the airbag should be deployed
using an SST before disposal (See page RS±73).
Perform the operation in a safe place away from
electrical noise.

DIAGNOSIS SYSTEM
1. Description

When troubleshooting On±Board Diagnostic (OBD ll) ve-
hicles, the vehicle must be connected to 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 Indicator Light (MIL)
on the instrument panel when the computer detects a
malfunction in: 1) the emission control system/compo-
nents, or 2) the powertrain control components (which af-
fect vehicle emissions), or 3) the computer. In addition,
the applicable Diagnostic Trouble Codes (DTCs) pre-
scribed by SAE J2012 are recorded in the ECM memory
(See page DI±58).
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 hand±held tes-
ter). The DTC includes SAE controlled codes and manufacturer
controlled codes. SAE controlled codes must be set according
to the SAE, while manufacturer controlled codes can be set by
a manufacturer with certain restrictions (See the DTC chart on
page DI±58).
2. NORMAL MODE AND CHECK MODE
The diagnosis system operates in ºnormal modeº during normal
vehicle use. In ºnormal modeº, 2 trip detection logic* is used to
ensure accurate detection of malfunctions. A ºcheck modeº is
also available to technicians as an option. In ºcheck modeº, 1
trip detection logic is used for simulating malfunction symptoms
and increasing the system's ability to detect malfunctions, in-
cluding intermittent malfunctions (See page DI±11).
3. 2±TRIP DETECTION LOGIC
When a malfunction is first detected, the malfunction is tempo-
rarily stored in the ECM memory. This is known as 1st trip detec-
tion. If the ignition switch is turned OFF and then ON again, and
the same malfunction is detected again, the MIL will illuminate.
This is known as 2nd trip detection.

WIRING DIAGRAM
Refer to DTC P0351 on page DI±221 for the wiring diagram of the ignition system.
CONFIRMATION DRIVING PATTERN
(a) Connect the hand±held tester to the DLC3.
(b) Record DTC and the freeze frame data.
(c) Use the hand±held tester to set the check mode (See page DI±44).
(d) Read the value on the misfire counter for each cylinder when idling. If the value is displayed on the
misfire counter, skip the following procedure of confirmation driving.
(e) Drive the vehicle several times with the engine speed, load and surrounding range shown as ENGINE
SPD, CALC LOAD in the freeze frame data or MISFIRE RPM, MISFIRE LOAD in the DATA LIST.
If you have no hand±held tester, turn the ignition switch OFF after the symptom is simulated once. Then re-
peat the simulation process again.
