SIR? precautions for stereo removal?

Post by Chiadog »

What do YOU do to disable airbags when removing radio/cd from the dash?????

This is out of the GM service/repair DVD:
Instrument Panel Disassembly Precautions
Caution: Refer to SIR Caution 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:
Service procedures require disconnection of the following components from the deployment loop in
order to avoid an accidental deployment:
Notice: 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).
1. Do not store the inflator modules at temperatures above 65°C (150°F).
2. Do not use the following components if dropped from a height of 91.4 cm (3 ft) or more.
3. Do not apply power to the SIR except under the following circumstances:
4. The SIR Diagnostic System Check is the starting point of any SIR diagnostics.
The SIR Diagnostic System Check will perform the following functions:
5. Bypassing the SIR Diagnostic System Check procedures may result in the following
circumstances:
• After the ignition switch is turned to LOCK.
• The battery is disconnected.
• The IGN fuse
• The CIG fuse
• The RADIO fuse
• The steering column circuit (SRS coil assembly and inflator module)
• Inflator modules
• Center sensory assemblies
• All the components are connected.
• A diagnostic chart requests power.
• Powering up the SIR with the components disconnected will set a DTC.
• 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
• Extended diagnostic time
• An incorrect diagnosis
• An incorrect parts replacement
