Air Bag(s) Arming and Disarming: Service and Repair
General Description
CAUTION:
-
When servicing a vehicle, be sure to turn the ignition switch to OFF, disconnect the ground cable from battery, and wait for 20 seconds or
more before starting work.
-
The airbag system is fitted with a backup power source. After disconnecting the battery ground cable, the airbag may deploy if you do
not wait for 20 seconds or more before starting airbag system servicing.
-
If the airbag warning light illuminates, repair the vehicle immediately. Otherwise, the airbag or pretensioner may inflate incorrectly, or
not inflate in collision.
-
If each airbag sensor, airbag module, airbag control module, pretensioner, harness or satellite safing sensor is deformed or damaged,
replace with a new part.
-
When checking the airbag system, be sure to use a digital circuit tester. Use of an analog circuit tester may cause the airbag to activate
erroneously due to a minimal current inside tester.
-
When checking, use a test harness (1). Damage to connector terminal cause malfunction. Do not directly apply the tester probe to
connector terminal of airbag.
