| • | 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 supplemental restraint Diagnostic Energy Reserve Module (DERM). |
| - | The supplemental restraint arming sensor. |
| - | The supplemental restraint steering wheel (inflator) module. |
| - | The supplemental restraint discriminating sensor. |
| - | The supplemental restraint steering wheel module coil. |
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
Supplemental Restraint System (SRS). |
| • | Discard any of the following components if it has been dropped
from a height of 91 centimeters (3 feet) or greater. |
| - | The supplemental restraint Diagnostic Energy Reserve Module (DERM). |
| - | The supplemental restraint arming sensor. |
| - | The supplemental restraint steering wheel (inflator) module. |
| - | The supplemental restraint discriminating sensor. |
| - | The supplemental restraint steering wheel module coil. |
Do not install the component in a vehicle.
| • | When you replace the DERM, 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 Supplemental Restraint System (SRS) when one of the following
two conditions is met: |
| - | All SRS components are properly mounted and electrically connected. |
| - | A diagnostic procedure directs you to apply power. |
| • | Begin diagnosis of malfunctions with the SRS Diagnostic System
Check. Perform the SRS Diagnostic System Check in order to verify the following: |
| - | The proper operation of the AIR BAG warning lamp. |
| - | Communication with the DERM 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 SRS Diagnostic System Check could cause extended
diagnostic time, incorrect diagnosis, and unneeded parts replacement.
