*1: RHD, *2: LHD, *3: w/ Curtain Shield Airbag
HINT:

When the SRS warning light remains on and the DTC is the normal code, a voltage source drop is sus-
pected.
This malfunction is not stored in memory by the airbag sensor assy center and if the power source
voltage returns to normal, the SRS warning light will automatically go off.

If a code not listed on the displayed chart, the airbag sensor assy center may be failed.

In the case of any malfunction concerning any open circuit, short to ground, or short to B+ due to any
squib, another malfunction code may not be detected. In this case, repair the malfunction currently
indicated and then perform malfunction diagnosis again. Another malfunction code may then be de-
tected.

PRE±CHECK
1.DIAGNOSIS SYSTEM
(a)Check the DLC3. (1)The vehicle's ECM conforms to ISO 9141±2 forcommunication protocol. The terminal arrangement
of the DLC3 complies with ISO 15031±3 and meets
the ISO 9141±2 format.
Terminal No.Connection/Voltage or ResistanceCondition
7Bus + Line/Pulse generationDuring Transmission
4Chassis Ground
Body Ground/1
or lessAlways
16Battery Positive
Body Ground/9 ± 14 VAlways
HINT:
If the display shows UNABLE TO CONNECT TO VEHICLE
when you connect the cable of the hand±held tester to the
DLC3, turn the ignition switch to the ON position and operate
the hand±held tester, there is a problem either on the vehicle
side or tool side.

If communication is normal when the tool is connected to
another vehicle, inspect the 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.
2.SRS WARNING LIGHT CHECK
(a)Turn the ignition switch to the ON position, and check that the SRS warning light comes on.
(b)Check that the SRS warning light goes off after approx.
6 seconds.
HINT:

When the ignition switch is ON position and the SRS
warning light remains on or flashes, the airbag sensor
assy center detects a malfunction code.

When the SRS warning light comes on even when the
ignition switch is in the LOCK position, trouble in the pow-
er source or combination meter assy is suspected. Pro-
ceed to ºSRS warning light circuit malfunction (Always
lights up, when ignition switch is LOCK position)º on page
05±1386.

When the ignition switch is turned from the LOCK to ON
position, the SRS warning light does not come on. Pro-
ceed to ºSRS warning light circuit malfunction (Does not
light up, when ignition switch is turned ON)º on page
05±1389.

3.DTC CHECK (USING SST CHECK WIRE)
(a)Output the DTCs (Present trouble code).
(1)Turn the ignition switch to the ON position, and wait
for approx. 60 seconds.
(2)Using SST, connect the TC and CG of the DLC3.
SST09843±18040
NOTICE:
Pay attention to the terminal connecting position to avoid
a malfunction.
(b)Output the DTCs (Past trouble code).
(1)Using SST, connect the TC and CG of the DLC3.
SST09843±18040
NOTICE:
Pay attention to the terminal connecting position to avoid
a malfunction. (2)Turn the ignition switch to the ON position, and wait
for approx. 60 seconds.
(c)Read the DTCs. (1)Read the DTC by counting the blinking times. Forexample, the blinking patterns for normal code,
code 11 and code 31 are shown in the illustration.

Normal code indication (w/o past trouble
code)
The light blinks twice per second.

Normal code indication (w/ past trouble code)
When the past trouble code is stored in the
airbag sensor assy center, the blinks only
once a second.

Malfunction code indication
The first blinking indicates the first DTC. Se-
cond blinking occurs after 1.5±second of
pause.
If there are 2 or more codes, there will be a 2.5±second pause
between each code. After all codes are shown, there will be a
4.0±second pause, and they will all be repeated.
HINT:

If 2 or more malfunctions are found, the indication starts
from the smaller numbered code.

If DTCs are indicated without a connection of the termi-
nals, proceed to the ºTC terminal circuitº on page
05±1391.
(d) Clear the DTCs. (1) When the ignition switch is turned off, the DTCs are cleared.
HINT:
Depending on the DTC, the code might not be cleared by turning off the ignition switch. In this case, proceed
to the next step.
