Air bag issues, dealer says bad passenger airbag.
So my 1997 has an airbag light. I took it to the dealer and they said that it was a bad passenger side airbag. I don't really fancy the idea of pulling e dash and putting in a new bag, or paying the dealer 980 bucks to do it either. I was wondering if there was a way to just trick the car into thinking the airbag was there and functioning?

Well,,, If it were ME, I would find the airbag and ALL the associated wiring and connectors for that loop.
NOTE! You have to DISCONNECT the battery and wait 20 min or so to allow the reserve stored charge in the firing capacitors to discharge.
Once you do that, just find the wiring and connectors and inspect them. DO NOT Ohm out the wires going to the bag module!!
Other than that, if everything looks good, you will need a new air bag assembly/module. Its really a simple loop. Try disconnecting and reconnecting each connector and see if the issue goes away.

Pull the codes as advised. Here is some info that should help.
B0017
CIRCUIT DESCRIPTION
The inflatable restraint I/P module deployment loop consists of the inflatable restraint I/P module and the I/P module high and low circuits. A shorting bar used within the I/P module connector shorts together the I/P module high and low circuits when the connector is disconnected. This helps to prevent unwanted deployment of the inflator module during servicing. During a frontal crash of sufficient force, the inflatable restraint sensing and diagnostic module (SDM) allows current to flow through the deployment loop in order to deploy the I/P module. When the ignition is turned ON, the SDM performs continuous diagnostic tests on the deployment loops to check for proper circuit continuity and for shorts to ground or voltage. If a malfunction is detected, a diagnostic trouble code (DTC) will be stored in memory.
CONDITIONS FOR RUNNING THE DTC
Ignition 1 voltage is within the normal operating voltage range.
CONDITIONS FOR SETTING THE DTC
DTC B0016 will set when the I/P module deployment loop resistance is less than 1.3 ohms for 300 milliseconds.
DTC B0017 will set when one of the following conditions occur:
I/P module high circuit is less than 2 volts and the I/P module deployment loop resistance is more than 3.7 ohms for 300 milliseconds.
I/P module deployment loop resistance is more than 6 ohms for 300 milliseconds.
DTC B0018 will set when one of the following conditions occur:
I/P module high circuit is more than 6 volts for 300 milliseconds.
I/P module high circuit is less than 2 volts and I/P module deployment loop resistance is less than6 ohms for 300 milliseconds.
ACTION TAKEN WHEN THE DTC SETS
The SDM commands the AIR BAG indicator ON via Class 2 serial data.
CONDITIONS FOR CLEARING THE DTC
The condition responsible for setting the DTC no longer exists and the scan tool Clear DTCs function is used.
A history DTC will clear once 255 malfunction free ignition cycles have occurred.
DIAGNOSTIC AIDS
The following are possible causes of the malfunction:
A short between the I/P module high and low circuits.
An open or a high resistance in the I/P module high or low circuits.
A short to ground or a short to voltage in the I/P module high or low circuits.
The I/P module connector
The SDM connector
A malfunctioning I/P module
A malfunctioning SDM
Thoroughly inspect the wiring and the connectors. An incomplete inspection of the wiring and the connectors may result in a misdiagnosis, causing a part replacement with the reappearance of the malfunction. If an intermittent malfunction exists, refer to Diagnostic Aids for Circuit Testing and Wiring Repair Procedures.
You may be able to connect a 2 ohm resistor in place of the air bag if it's bad and you don't won't to replace it.

Good deal, thanks for all of the information! Seems like it may be a bit over my head... Really interested mostly in just getting rid of the light on my dash lol
