- 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 IP (inflator) module. |
• | The inflatable restraint steering wheel (inflator) module. |
• | The inflatable restraint steering wheel module coil. |
• | The inflatable restraint front end discriminating sensor. |
• | The inflatable restraint side impact sensing modules (SISM) |
• | The inflatable restraint side impact (inflator) modules |
- 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. Do not
install the component in a vehicle.
• | 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. |
• | The inflatable restraint front end discriminating sensor. |
• | The inflatable restraint side impact sensing modules (SISM) |
• | The inflatable restraint side impact (inflator) modules |
- 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. |
- When you replace a SISM, verify that the following conditions
are met:
• | The mounting surface is clean. |
• | The module is flat on the mounting surface. |
• | 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 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 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
the following:
• | Extended diagnostic time. |
• | Unneeded parts replacement. |
