• When servicing a vehicle, be sure to turn the ig-
nition switch OFF, disconnect the ground cable
from the battery, and wait for more than 20 seconds
before starting work.

source. If the airbag system is serviced within 20
seconds after the ground cable is disconnected, it
may inflate.

pretensioner, and harness are deformed or dam-
aged, replace them with new genuine parts.
• When checking the system, be sure to use a dig-
ital circuit tester.
Use of an analog circuit tester may cause the air-
bag to activate erroneously.

rectly apply the tester probe to any connector termi-
nal of the airbag.
