General Service Instructions

^ 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:
- The inflatable restraint Sensing and Diagnostic Module (SDM).
- The inflatable restraint I/P inflator module.
- The inflatable restraint steering wheel inflator module.
- The inflatable restraint front end discriminating sensor.
- The inflatable restraint steering wheel module coil.
- The inflatable restraint Side Impact Sensing Modules (SISM).
- The inflatable restraint side impact inflator modules.
Service these components by replacement only.

^ 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 it has been dropped from a height of 91 centimeters (3 feet) or greater.
- The inflatable restraint Sensing and Diagnostic Module (SDM).
- The inflatable restraint I/P inflator module.
- The inflatable restraint steering wheel inflator module.
- The inflatable restraint front end discriminating sensor.
- The inflatable restraint steering wheel module coil.
- The inflatable restraint Side Impact Sensing Modules (SISM).
- The inflatable restraint side impact inflator modules.
Do not install the component in a vehicle.

^ When you replace the inflatable restraint Sensing and Diagnostic Module (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.
When you replace the inflatable restraint Side Impact Sensing Module (SISM), verify that the following conditions are met:
- The mounting surface is clean.
- Position the SISM on the mounting surface.
- Point the connector on the SISM toward the rear of the vehicle.
- Tighten all of the SISM module fasteners to the specified value.

^ 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.

^ Begin diagnosis of malfunctions with the SIR DIAGNOSTIC SYSTEM CHECK. Perform the SIR DIAGNOSTIC SYSTEM CHECK in order to verify the following:
- The proper operation of the AIR BAG warning lamp.
- Communication with the inflatable restraint Sensing and Diagnostic Module (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 could cause extended diagnostic time, incorrect diagnosis, and unneeded parts replacement.
