Switches, Display Light, Wiring Connections

Switches

One switch kit will be required for each air bag (driver or passenger) and will be ignition key operated. When the switch is in the "OFF" position, the air bag will remain "OFF" until the switch is turned to the "ON" position. Turning the switch to the "ON" position will allow the air bag to function.

The recommended locations for the switches on most vehicles is in the instrument panel glove compartment (center console if vehicle has no glove compartment) or, in the case of some vans, in the center stowage compartment (see the recommended location illustrations that are provided with each switch kit).

Important:
Switches or display light indicators must not be placed on any instrument panel surfaces directly in front of the driver's or passenger's leg or knee areas.

Display Light

Each switch requires a display light to indicate the
"OFF" status of the air bag. Each display light includes a harness to be connected to the switch harness. The recommended mounting locations for the display lights vary, but are typically located at the center front edge of the roof headliner (or windshield garnish molding) above the rear view mirror (see the recommended location illustrations provided with each switch kit).

Important:
When installed, driver and/or passenger display light(s) must be visible by all front seat occupants.

Important:
Switches or display light indicators MUST NOT be placed on any instrument panel surfaces directly in front of the driver's or passenger's leg or knee areas.

Wiring Connections

In general terms, the switch will be connected "in series" with the appropriate air bag (at the service disconnect) and will require additional connection of a feed wire to an ignition fed circuit and a ground wire to the body to complete the circuit for the display light indicator.











Diagnostics for the switch and display light are included with this bulletin.

As always, the technician should make sure to review the wiring harness routing and installation for pinching, rubbing and chafing to brackets, braces (etc.) and take appropriate actions to protect the wiring from those potential conditions.
