Passenger Airbag Module Replacement

After deployment, a powdery residue may be on the surface of the airbag. The powder consists primarily of cornstarch (used to lubricate the bag as it inflates) and by-products of the chemical reaction. Sodium hydroxide dust (similar to lye soap) is produced as a by-product of the deployment reaction. The sodium hydroxide then quickly reacts with atmospheric moisture and is converted to sodium carbonate and sodium bicarbonate (also known as baking soda). Therefore, it is unlikely that sodium hydroxide will be present after deployment. Wear gloves and safety glasses during the disposal procedure. Refer to "Deployed Airbag Module Disposal Procedure".

Removal Procedure

CAUTION: The SDM can maintain sufficient voltage to deploy the airbags for 10 minutes after the ignition if OFF or the AIRBAG fuse has been removed.




1. Turn the ignition switch to LOCK and remove the key.
2. Remove the glove box. Refer to Instrumentation/Driver Information.
3. Disconnect the passenger airbag yellow electrical connector.
4. Remove the lower nuts and bolts from the airbag bracket.




5. Remove the upper nuts from the studs on the airbag bracket.
6. If necessary, use a hammer to lightly tap the studs in an upward direction to free the studs from the instrument panel.
7. Remove the passenger airbag module from the instrument panel.

Installation Procedure




1. Install the passenger airbag module in the instrument panel.
2. Install the upper nuts on the airbag bracket studs.
Tighten
Tighten the passenger airbag bracket upper nuts to 8 Nm (71 lb.in).




3. Install the bracket lower nuts and bolts.
Tighten
Tighten the passenger airbag bracket lower nuts and bolts to 16 Nm (12 lb.ft).

4. Connect the passenger airbag electrical connector.
5. Install the glove box. Refer to Instrumentation/Driver Information.
6. Perform the SIR Diagnostic System Check.
