(c) Read the DTC.
Read the 2±digit DTC as indicated by the number of times
the SRS warning light blinks. As an example, the blinking
patterns, normal, 11 and 31 are shown in the illustration.
Normal code indication
The light will blink 2 times per second.
Malfunction code indication
The first blinking output indicates the first digit
of a 2±digit DTC. After a 1.5±second pause,
the second blinking output will indicate the
second digit.
If there are 2 or more codes, there will be a 2.5±second pause
between each code. After all the codes have been output, there
will be a 4.0±second pause and they will all be repeated.
HINT:
In the event of a number of trouble codes, indication will
start from the smallest numbered code.
If a DTC is not output or a DTC is output without terminal
connection, proceed to the Tc terminal circuit inspection
on page DI±796.
3. DTC CHECK (Using TOYOTA hand±held tester)
(a) Hook up the TOYOTA hand±held tester to the DLC1 or
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.
4. DTC CLEARANCE (Not using service wire)
When the ignition switch is turned off, the diagnostic trouble
code is cleared.
HINT:
DTC might not be cleared by turning the ignition switch OFF.
In this case, proceed to the next step.
5. DTC CLEARANCE (Using service wire)
(a) Connect the 2 service wires to terminals Tc and AB of
DLC1.
(b) Turn the ignition switch to ACC or ON and wait for approx.
6 seconds.

(c) Starting with the Tc terminal, ground alternately terminal
Tc and terminal AB twice each in cycles of 1.0 seconds.
Make sure that the terminals are grounded. Ensure the
terminal Tc remain grounded.
HINT:
When alternately grounding terminals Tc and AB, release
ground from one terminal and immediately ground the other ter-
minal within an interval of 0.2 seconds.
If DTCs are not cleared, repeat the above procedure until the
codes are cleared.
(d) Several seconds after doing the clearing procedure, the
SRS warning light will blink in a 50 m sec. cycle to indicate
the codes which have been cleared.

HINT:
When the SRS warning light remains lit up and the DTC is the normal code, this means a voltage source
drops.
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, the codes will be displayed in numeral order starting from the
lowest numbered code.
If a code not listed on the chart is displayed, the airbag sensor assembly is faulty.
