General Service Instructions
1. Inflator modules should not be subjected to temperatures above 65°C (150°F).
2. Inflator modules or Sensing and Diagnostic Module (SDM) should not be used if they have been dropped from a height of 91.4 centimeters (3 feet) or greater.
3. When a SDM is replaced, it MUST be oriented with the arrow on the sensor pointing toward the front of the vehicle. It is very important for the SDM to be located flat on the mounting surface. parallel to the vehicle datum line. It is important that the mounting surface is free of any dirt or other foreign material.
4. Do not apply power to the SIR system unless all components are connected or a diagnostic chart requests it, as this will set a diagnostic trouble code.
5. The "SIR Diagnostic System Check" must be the starting point of any SIR diagnostics. The "SIR Diagnostic System Check" will verify proper "AIR BAG" warning lamp operation and will lead you to the correct chart to diagnose any SIR malfunctions. Bypassing these procedures may result in extended diagnostic time, incorrect diagnosis, and incorrect parts replacements.
