vicing.

repair the vehicle immediately to prevent it from air-
bag system malfunction.

bag control module, pretensioner, harness or satel-
lite safing sensor cover is deformed or damaged,

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.
