REPAIR AIRBAG MANUAL DEPLOYMENT
CAUTION: Deployment in the vehicle will
damage the steering wheel; if the vehicle
is not being scrapped deploy the module
away from the vehicle in accordance with the
separate procedure.
If a vehicle is to be scrapped and contains an
undeployed airbag module, the module must be
manually deployed. This operation should only be
carried out using the following recommended manual
deployment procedure.
Before deployment is started the deployment tool self
test procedure should be carried out.
Deployment tool SMD 4082/1 self test procedure
1.Insert BLUE and YELLOW connectors of tool
lead into corresponding sockets on face of tool.
2.Connect crocodile clips of second tool lead to
battery, RED to positive and BLACK to negative.
3.RED "READY" light should illuminate.
4.Press and hold both operating buttons.5.GREEN "DEFECTIVE" light should illuminate.
6.Release both operating buttons.
7.RED "READY" light should illuminate.
8.Disconnect tool from battery.
9.Disconnect blue and yellow connectors from tool
face sockets.
10.Self test now complete.
Deployment with module fitted to vehicle
These guidelines are written to aid authorised
personnel to carry out the safe disposal of the airbag
module when fitted to the vehicle.
WARNING: Only use the LAND ROVER
approved deployment equipment. Deploy
airbag module in a well ventilated
designated area. Ensure airbag module is not
damaged or ruptured before deploying.
