Hi & welcome. Here's some info for you to look at.

INFLATABLE RESTRAINT IP MODULE SWITCH (PICKUP AND EXTENDED CAB ONLY)
The inflatable restraint IP module switch is a manual two-position key switch located in the instrument panel, to the right of the steering wheel. This switch gives the vehicle operator the ability to enable or disable the inflatable restraint IP module (passenger front air bag) deployment should the vehicle be involved in a severe frontal collision. The vehicle operator may choose to disable the inflatable restraint IP module if there is no occupant in front seat, or if there is a child in a rear-facing child seat in the front seat.

The manual key-switch operates in two positions. When the key is vertical, the switch is in the OFF position and the inflatable restraint IP module is in the suppressed (disabled) state. In the suppressed state, the inflatable restraint IP module will not deploy in the event of a severe frontal collision. When the key is horizontal, the switch is in the ON position and the inflatable restraint IP module is in the nonsuppressed (enabled) state. In the nonsuppressed state, the inflatable restraint IP module will deploy in the event of a severe frontal collision. The key-switch assembly also includes a backlit switch cover which illuminates when the headlights are ON.

If you need reable procedures I will do it this evening. I have to leave now. Thanks.
