IMPORTANT:Failure to follow instructions below may result in the accidental deployment of “airbag”, “seat belt”, which increases the risk of serious personal injury or death.

• Never probe the electrical connectors on airbag or seat belt.
• Never disassemble or tamper with safety belt buckle/retractor pretensioners, adaptive load limiting retractors, safety belt inflators, or probe the electrical connectors.
• Do not use electrical test equipment to check SRS circuits unless instructed to in this Service Manual.
• Before servicing the SRS, turn ignition switch OFF, disconnect both battery cables and wait at least 3 minutes. For approximately 3 minutes after the cables are removed, it is still possible for the airbag and seat belt pre-tensioner to deploy. Therefore, do not work on any SRS connectors or wires until at least 3 minutes have passed.

3. You are now safe to unplug the airbag control module harness wiring plugs.
