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.
- Service these components by replacement only.
- Do not repair any of the following components:
- The supplemental restraint sensing and diagnostic module (SDM)
- The supplemental restraint IP module
- The supplemental restraint IP module switch
- The supplemental restraint steering wheel module
- The supplemental restraint steering wheel module coil
- The supplemental restraint front end discriminating sensor

- Use only original replacement parts available from your authorized dealer. Do not use salvaged parts for repairs to the SRS system.

- Discard any of the following components if the components have been dropped from a height of 91 centimeters (3 ft) or greater.
- The supplemental restraint sensing and diagnostic module (SDM)
- The supplemental restraint IP module
- The supplemental restraint IP module switch
- The supplemental restraint steering wheel module
- The supplemental restraint steering wheel module coil
- The supplemental restraint front end discriminating sensor

- 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 tine.
- The module fasteners are installed and tightened as specified.

- In order to avoid setting false diagnostic trouble codes, only apply power to the SRS system when one of the following two conditions is met:
- All SRS system components are properly mounted and electrically connected.
- A diagnostic procedure directs you to apply power.

- Begin diagnosis of malfunctions with a Diagnostic System Check - SRS. Perform a Diagnostic System Check-SRS in order to verify the following:
- The 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 a Diagnostic System Check - SRS could cause the following:
- Extended diagnostic time
- Incorrect diagnosis
- Unneeded parts replacement
