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 is 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.
