*1: w/ Side Airbag
HINT:
When the SRS warning light remains lit up and the DTC is the normal code, a voltage source drop is
possible.
This malfunction is not stored in memory by the airbag sensor assembly and if the power source volt-
age returns to normal, the SRS warning light will automatically go out.
When 2 or more codes are indicated, smaller numbered code will be shown first.
If a code not listed on the chart is displayed, the airbag sensor assembly is at fault.
In the case of any malfunction concerning any open circuit, ground short, or B+ short due to any squib,
another malfunction code may not be detected. In this case, correct the malfunction currently indicated
and then perform malfunction diagnosis again. Another malfunction code may then be detected.

PRE-CHECK
1. DIAGNOSIS SYSTEM
(a) Check the DLC3.
HINT:
The vehicle's ECM uses ISO 9141-2 for communication. The
terminal arrangement of the DLC3 complies with SAE J1962
and matches the ISO 9141-2 format.
Terminal No.Connection/Voltage or ResistanceCondition
7Bus Line/Pulse generationDuring Transmission
4Chassis Ground e Body Ground/1 W or lessAlways
16Battery Positive e Body Ground/ 9 - 14 VAlways
HINT:
If your display shows UNABLE TO CONNECT TO VEHICLE
when you have connected the cable of the OBD II scan tool or
TOYOTA hand-held tester to the DLC3, turned the ignition
switch ON and operated the scan tool, there is a problem on the
vehicle side or tool side.
If communication is normal when the tool is con-
nected to another vehicle, inspect the DLC3 on the
original vehicle.
If communication is still not possible when the tool
is connected to another vehicle, the problem is
probably in the tool itself, so consult the Service De-
partment listed in the tool's instruction manual.
2. SRS WARNING LIGHT CHECK
(a) Turn the ignition switch to ON, and check that the SRS
warning light comes on.
(b) Check that the SRS warning light goes out after approx.
6 seconds.
HINT:
When the ignition switch is at ON and the SRS warning
light remains on or flashes, the airbag sensor assembly
has detected a malfunction code.
If, after approx. 6 seconds have elapsed, the SRS warn-
ing light sometimes comes on even when the ignition
switch is OFF. In this case, a short in the SRS warning light
circuit is possible. Proceed to ºSRS warning light circuit
malfunctionº on page DI-927.

(c) Read the DTC.
Read the DTC by counting the blinking times. As an ex-
ample, the blinking patterns of normal, 11 and 31 are
shown in the illustration.
Normal code indication (w/o past trouble
code)
The light blinks 2 times per seconds.
Normal code indication (w/ past trouble code)
When the past troubles code is stored in the
airbag sensor assembly, the light blinks only
ones a second.
Malfunction code indication
The first blinking indicates the first DTC. Se-
cond blinking occurs after 1.5- second of
pausing.
If there are 2 or more codes, there will be a 2.5-second pause
between each code. After all the codes are shown, there will be
a 4.0-second pausing, and they will all be repeated.
HINT:
If 2 or more malfunctions are found, the indication starts
from the smaller numbered code.
If the light does not blink or comes out at all, or if DTCs are
indicated without a connection of the terminals, proceed
to the TC terminal circuit inspection on page DI-932.
4. DTC CHECK (Using TOYOTA hand-held tester)
(a) Hook up the TOYOTA hand-held tester to the DLC3.
(b) Read the DTCs by following the prompts on the tester
screen.
HINT:
Please refer to the TOYOTA hand-held tester operator's manu-
al for further details.
5. DTC CLEARANCE (Not using service wire)
When the ignition switch is turned OFF, the diagnostic trouble
code is cleared.
HINT:
Depending on the DTC, the code might not be cleared by turn-
ing the ignition switch OFF.
In this case, proceed to the next step.
6. DTC CLEARANCE (Using service wire)
(a) Connect the service wire to terminal TC of the DLC3.
(b) Ground terminal TC of the DLC3.
(c) Turn the ignition switch to the ON position.
(d) Within 3 to 10 sec. after DTC is started to be output, re-
lease ground from terminal TC of the DLC3.
(e) The SRS warning light comes on 2 to 4 sec. later. Within
1 to 5 sec. after that, ground terminal TC of the DLC3.
(f) The SRS warning light goes off 2 to 4 sec. after grounding
terminal TC. Within 1 to 5 sec. after that, release ground
from terminal TC again.

(g) The SRS warning light comes on again 2 to 4 sec. later.
Within 1 to 5 sec. after that, ground terminal TC of the
DLC3 again.
(h) The SRS warning light goes off 2 to 4 sec. later. Within 1
sec. after that, normal code is output indicating that DTC
deletion is completed.
If DTCs are not cleared, repeat the above procedure until the
codes are cleared.
