1. General
A: PRECAUTION
IIf any of the airbag system parts such as
sensors, airbag module, airbag control module and
harness are damaged or deformed, replace with
new genuine parts.
G5M0291
IWhen servicing, be sure to turn the ignition
switch off, disconnect the negative (þ) battery ter-
minal then the positive (+) terminal in advance, and
wait for more than 20 seconds before starting
work.
G5M0292
IWhen checking the system, be sure to use a
digital circuit tester. Use of an analog circuit tester
may cause the airbag to activate erroneously. Do
not directly apply the tester probe to any connec-
tor terminal of the airbag. When checking, use a
test harness.
