WD.6 - SAFETY PRECAUTIONS, SHIPPING, STORAGE & DISPOSAL
WARNING: The SDM can maintain sufficient voltage to cause an airbag deployment for up to 20
seconds after the battery has been disconnected. Before working on the airbag system, or in close
proximity to an airbag, first take the following precautions to temporarily disable the airbag system:
1. Turn off the ignition.
2. Before disconnecting the battery, use the Lotus Scan tool to read any stored trouble codes.
3. Disconnect the negative (earth) lead from the battery and tape back to ensure that no contact with the
battery negative terminal can be made.
4. Wait for 30 seconds.
5. If working on or near the steering wheel, locate the yellow harness connector alongside the steering
column near the column upper fixing. Unplug this connector. Note that the connector is fitted with
'shorting bars' which automatically interconnect the high and low terminals of the airbag to prevent acci-
dental deployment caused by a voltage differential.
When service work has been completed, reconnect the harness plug and secure with its locking feature,
and reconnect the battery. Ensure the airbag tell tale lights for a few seconds with ignition and then goes out.
Storage
- Airbag modules and SDMs should not be stored at temperatures above 176°F (80°C).
- Airbag modules and SDMs should not be stored in damp conditions.
- Do not store airbag module or SDM boxes more than two high.
- Always store and handle airbag modules and SDMs in an upright position. Never store SDMs upside
down.
Sensor & Diagnostic Module (SDM)
The SDM is calibrated specifically to the Elise/Exige, and is mounted on a dedicated bracket to the scuttle
beam. Never use an SDM from another vehicle, or modify its mounting to the Elise/Exige.
WARNING:
•
Handle the SDM with great care. Never strike or jar the SDM as this could cause airbag deploy-
ment and result in personal injury or improper operation of the SRS.
•
All module and mounting bracket bolts must be correctly installed and tightened to assure proper
security and operation.
•
Never power up the SRS when the SDM is not properly mounted and secured, since the SDM is
easily triggered when not attached, and could result in deployment causing personal injury.
•
Do not use or attempt to repair a damaged SDM.
Inflator Module
Live (Undeployed) Inflator Modules: Special care is necessary when handling and storing a live (undeployed)
inflator module. In the unlikely event of accidental deployment, the rapid gas generation produced during
deployment of the air bag could cause violent movement of the inflator module or surrounding objects, and
result in personal injury.
WARNING:
•
When carrying a live inflator 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 inflator 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 air bag to expand in the unlikely event of accidental deployment. Otherwise, personal injury
may result.
•
Never carry the inflator module by the wires or connector on the underside of the module.
•
Do not use or attempt to repair a damaged inflator module, and NEVER apply any electrical power
to the module except as specified in the diagnostic procedures.
Inflator Module Shipping Procedures for Live (Undeployed) Inflator Modules
The transportation of uninstalled inflator modules is regulated by the Hazardous Materials Regulations of
