(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±313.
3. 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.
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) Turn ignition switch to LOCK, and wait at least for 20 se-
conds.
(d) Turn ignition switch to ACC or ON, and wait at least for 20
seconds.
(e) Check DTC (See page DI±223).
OK:
DTC B0100/13 is not output.
