| • | Do not expose the inflator modules to temperatures above 65°C
(150°F). |
| • | Verify the correct replacement part number. Do not substitute
a component from a different vehicle. |
| • | Do not repair any of the following components. Service these components
by replacement only: |
| - | The inflatable restraint sensing and diagnostic module (SDM) |
| - | The inflatable restraint I/P module |
| - | The inflatable restraint steering wheel module |
| - | The inflatable restraint steering wheel module coil |
| - | The inflatable restraint side impact sensors (SIS) |
| - | The inflatable restraint side impact modules |
| - | The seat belt pretensioners |
| • | Use only original GM replacement parts available from your authorized
GM dealer. Do not use salvaged parts for repairs to the SIR system. |
| • | Discard any of the following components if the component has been
dropped from a height of 91 centimeters (3 feet) or greater. |
| - | The inflatable restraint sensing and diagnostic module (SDM) |
| - | The inflatable restraint IP module |
| - | The inflatable restraint steering wheel module |
| - | The inflatable restraint steering wheel module coil |
| - | The inflatable restraint side impact sensors (SIS) |
| - | The inflatable restraint side impact modules |
| - | The seat belt pretensioners |
| • | When you replace the SDM, verify that the following conditions
are met: |
| - | The mounting surface is clean. |
| - | The arrow on the module points toward the front of the vehicle. |
| - | The SDM is flat on the mounting surface, parallel to the vehicle
datum line. |
| - | The SDM fasteners are installed and tightened as specified. |
| • | When you replace an inflatable restraint side impact sensor (SIS),
verify that the following conditions are met: |
| - | The mounting surface is clean. |
| - | The SIS is flat on the mounting surface. |
| - | The SIS fasteners are installed and tightened as specified. |
| • | In order to avoid setting false diagnostic trouble codes, only
apply power to the SIR system when one of the following two conditions is
met: |
| - | All SIR system components are properly mounted and electrically
connected. |
| - | A diagnostic procedure directs you to apply power. |
