(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.
6. DTC CLEARANCE (Using TOYOTA hand±held tester)
(a) Hook up the TOYOTA hand±held tester to the DLC3.
(b) Clear the DTCs by following the prompts on the tester
screen.
HINT:
Please refer to the TOYOTA hand±held tester operation's
manual for further details.

7. RELEASE METHOD OF AIRBAG ACTIVATION PRE-
VENTION MECHANISM
An airbag activation prevention mechanism is built into the con-
nector for the squib circuit of the SRS.
When release of the airbag activation prevention mechanism is
directed in the troubleshooting procedure as shown in the il-
lustration of the connectors on the next pages, insert paper
which has the same thickness as the male terminal, between
the terminal and the short spring.
CAUTION:
Never release the airbag activation prevention mechanism
on the steering wheel pad connector.
NOTICE:
Do not release the airbag activation prevention mech-
anism unless specifically directed by the trouble-
shooting procedure.
If the inserted paper is too thick the terminal and short
spring may be damaged, so always use paper with
the same thickness as the male terminal.

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.
