1. Precaution
1) If any of the airbag system parts such as sensors, air-
bag module, airbag control module and harness are dam-
aged or deformed, replace with new genuine parts.
G5M0292
2) When servicing, be sure to turn the ignition switch off,
disconnect the negative () battery terminal then the posi-
tive (+) terminal in advance, and wait for more than 20
seconds before starting work.

2. Inspection and Replacement
Standards
1. VEHICLES WHICH BECOME INVOLVED IN A
COLLISION
If the vehicle equipped with an SRS airbag system is
damaged in a collision, the airbag system parts must
be checked and replaced in accordance with the fol-
lowing standards:
After faulty parts are replaced, the warning light opera-
tion must be checked.
When the ignition switch is turned ON, it lights up
for 8 seconds and then it goes out for at least 30 sec-
onds.
The trouble code stored in memory must be erased
after the check.
2. AIRBAG MODULE (DRIVER AND PASSENGER)
Inspection standard:
The vehicle damaged in a collision (regardless of
whether or not airbag is deployed).
The designated trouble code is output during self-diag-
nosis. (Refer to“Diagnostics”Section.)
Replacement standard:
Airbag is deployed.
The pad surface is scratched or cracked.
Harness and/or connector is deformed or cracked, their
circuits are broken, lead wire is exposed, etc.
Mounting bracket is cracked or deformed.
The module surface is fouled with foreign matter.
