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, Oppie

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, Oppie
