| • | 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 the following
components by replacement only: |
| - | The inflatable restraint sensing and diagnostic module (SDM) |
| - | The inflatable restraint IP (inflator) module |
| - | The inflatable restraint steering wheel (inflator) module |
| - | The inflatable restraint steering wheel module coil |
| • | Use only new or remanufactured parts from an authorized original
equipment manufacturer dealer. Do not use salvaged parts for repairs to the
SIR system. |
| • | Discard any of the following components if the components have
been dropped from a height of 91 centimeters (3 feet) or greater. |
| - | The inflatable restraint sensing and diagnostic module (SDM) |
| - | The inflatable restraint IP (inflator) module |
| - | The inflatable restraint steering wheel (inflator) module |
| - | The inflatable restraint steering wheel module coil |
Do not install the component in a vehicle.
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 module is flat on the mounting surface, parallel to the vehicle
datum line. |
| • | The module fasteners are installed and tightened as specified. |
In order to avoid setting false diagnostic trouble codes, only apply
power to the SIR system when 1 of the following 2 conditions
is met:
| • | All SIR system components are properly mounted and electrically
connected. |
| • | A diagnostic procedure directs you to apply power. |
Begin diagnosis of malfunctions with the SIR Diagnostic System Check.
Perform the SIR Diagnostic System Check in order to verify the following
conditions exist:
| • | Proper operation of the AIR BAG warning lamp |
| • | Communication with the SDM through the serial data line |
| • | The presence or absence of diagnostic trouble codes |
| • | Whether additional diagnosis is required and where the information
resides |
Not beginning with the SIR Diagnostic System Check may cause extended
diagnostic time, incorrect diagnosis, and unneeded parts replacement.
