Disabling airbags for service?

The owner's manual for the '01 LW300 has a warning about performing any
service that might trigger the airbags. Can anybody please tell what
servicing conditions this refers to and how to disarm the airbags during
service?

The only concrete warnings written were to keep away from yellow tagged
wires, yellow connectors and yellow coverings; that these are most likely
part of the airbag system. Also that the bags can trigger for up to 1 minute
after ignition is switched off and battery disconnected.

TIA for the info,

This is likely only necessary for when you are working in close proximity to
airbag system wiring, or to the inflator modules or sensing/diagnostic
module (in the center console). These cars don't have any external impact
sensors that you have to worry about, unless you have side airbags, in which
case there is a sensor around the door pillar on each side.

To disable the system, you'd just have to remove the air bag fuse, and then
disconnect the connector for the inflator modules you're working near, if
any.

Also, as you noted, "In the event that ignition positive voltage is lost
during a collision, the SDM maintains a 23-volt loop reserve (23 VLR) for
deployment of the air bags. It is important when disabling the SIR system
for servicing or rescue operations to allow the 23 VLR to dissipate, which
could take up to 1 minute."

 

Good reply. thanks for the info. We just have front airbags and this is my
first vehicle with them. Last vehicle was an '89 Voyager that just blew the
motor at 205k miles.

Happy New Year,
