Brought to you by Eris Studios NOT FOR RESALE AB-5 General Description AIRBAG SYSTEM B: CAUTION • When servicing a vehicle, be sure to turn the ig- nition 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 di- rectly apply the tester probe to connector terminal of airbag. • Do not allow water or oil to come in contact with the connector terminals. Also do not touch the connector terminals. • Do not check continuity of the airbag modules for driver’s side, passenger’s side and curtain, or the pretensioner.
