(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.
