WARNING / CAUTION labels are attached on each part of air bag system components (SDM, air bag (inflator) modules and seat belt pretensioners). Be sure to follow the instructions.
•
Many of service procedures require disconnection of “AIR BAG” fuse and air bag (inflator) module(s) (driver and passenger) from initiator circuit to avoid an accidental deployment.
•
Do not apply power to the air bag system unless all components are connected or a diagnostic flow requests it, as this will set a DTC.
•
The
Air Bag Diagnostic System Check
must be the starting point of any air bag diagnostics. The
Air Bag Diagnostic System Check
will verify proper “AIR BAG” warning lamp operation and will lead you to the correct table to diagnose any air bag malfunctions. Bypassing these procedures may result in extended diagnostic time, incorrect diagnosis, and incorrect parts replacements.
•
Never use air bag component parts from another vehicle.
•
If the vehicle will be exposed to temperatures over 93 °C (200 °F) (for example, during a paint baking process), remove the air bag system components beforehand to avoid component damage or unintended system activation.
•
When handling the air bag (inflator) modules (driver and passenger), seat belt pretensioners (driver and passenger), forward sensor or SDM, be careful not to drop it or apply an impact to it. If an excessive impact was applied (e.g., dropped from a height of 90 cm (3 ft) or more) never attempt disassembly or repair but replace it with a new one.
•
When using electric welding, be sure to disconnect air bag (inflator) module connectors (driver and passenger) and seat belt pretensioner connectors (driver and passenger) respectively.
•
When applying paint around the air bag system related parts, use care so that the harness or connector will not be exposed to the paint mist.
•
Never expose air bag system component parts directly to hot air (drying or baking the vehicle after painting) or flames.
