When checking the system, be sure to use a digital circuit tester. Use of an analog circuit tester may cause the airbag to activate erroneously.
When checking, use a test harness. Do not directly apply the tester probe to any connector terminal of the airbag.
Do not drop the airbag modulator parts, subject them to high temperature over 93°C (199°F), or let water, oil, or grease get on them; otherwise, the
internal parts may be damaged and reliability greatly lowered.
