Warning: Refer to SIR Warning in the Preface section.
The center sensor assembly may maintain sufficient voltage in order to cause a deployment for up to 2 minutes. This deployment may occur under one of the following circumstances:
| • | After the ignition switch is turned to LOCK. |
| • | The battery is disconnected. |
Service procedures require disconnection of the following components from the deployment loop in order to avoid an accidental deployment:
| • | The steering column circuit (SRS coil assembly and inflator module) |
Caution: In order to prevent possible Electrostatic Discharge damage to the PCM, Do Not touch the connector pins or the soldered components on the circuit board.
Some solid-state electrical components may be damaged by electrostatic discharge (ESD).
- Do not store the inflator modules at temperatures above 65°C (150°F).
- Do not use the following components if dropped from a height of 91.4 cm (3 ft) or more.
| • | Center sensory assemblies |
- Do not apply power to the SIR except under the following circumstances:
| • | All the components are connected. |
| • | A diagnostic chart requests power. |
| • | Powering up the SIR with the components disconnected will set a DTC. |
- The SIR Diagnostic System Check is the starting point of any SIR diagnostics.
The SIR Diagnostic System Check will perform the following functions:
| • | Verify the proper air bag indicator operation |
| • | Lead you to the correct chart in order to diagnose any SIR faults to avoid an extended diagnostic time |
- Bypassing the SIR Diagnostic System Check procedures may result in the following circumstances:
| • | Extended diagnostic time |
| • | An incorrect parts replacement |
