Lotus Service Notes
WARNING: The harness connector for the passenger's airbag is accessible only after removing the
fascia top panel, so care should be taken to avoid working in close proximity to the airbag door in case
of unintended deployment.
To replace passenger's airbag
WARNING: The following procedures must be followed in the order listed to temporarily disable the
airbag system whilst working in the immediate vicinity of an airbag. Failure to follow this procedure
could cause unintended airbag deployment, resulting in personal injury and unnecessary airbag system
repairs.
a). Turn off ignition.
b). Disconnect the negative battery cable, and tape back to ensure that it cannot contact the battery terminal.
c). From alongside the steering column, in the area of the column upper fixing, locate and disconnect the
yellow driver's airbag harness connector plug.
1. For access to the passenger's airbag module, the fascia top panel must first be removed. Refer to sub-
section WD.8.
2. From the right hand end of the airbag module, pull out the security tag and unplug the harness connector.
3. Release the two nuts and remove the airbag door tether strap bracket from the module mounting bracket.
4. Release the four nuts and the dash steady brackets securing the airbag module, and withdraw the module
from its mounting bracket.
WARNING: When carrying a live airbag module, make sure the bag and trim cover are pointed away
from you. In case of an accidental deployment, the bag will then deploy with minimal chance of injury.
When placing a live airbag module on a bench or other surface, always face the bag and trim cover
upwards, away from the surface. This is necessary so that a free space is provided to allow the airbag
to expand in the unlikely event of accidental deployment.
5. If an airbag deployment has occurred, the chassis scuttle beam, airbag mounting bracket, dash extru-
sions and all associated parts must be carefully examined for distortion and renewed where necessary.
WARNING: Proper operation of the SRS system requires that the vehicle structure remains in its
original production configuration. Any damage to the SRS components and/or their respective mounting
brackets, including the chassis, requires replacement, not repair.
6. If necessary, fit the airbag mounting brackets to the scuttle beam, and tighten the four M8 fixing bolts to
15 Nm.
7. Fit the airbag module to the mounting brackets, together with the dash steady brackets. Tighten the four
M6 nuts to 6 Nm.
8. Fit the airbox door tether strap bracket to the airbag module mounting bracket, and tighten the two nuts to
10 Nm.
9. Plug in the harness connector into the RH side of the module and retain with the security tag.
10. Refit the fascia top panel (see sub-section WD.8).
11. Refit the column shrouds, and when all service work is complete, mate the horn/airbag connector to the
vehicle harness (clipping the connector to the column) and reconnect the battery. Check that the airbag
tell tale lights for a few seconds with ignition, and then goes out.
