There's this website www.reliable-store.com
They have books on ALL vehicles.

it covers wiring diagrams, electrical diagrams, fuse diagram, torque specs, PCV, error codes, fault codes, service info, repair info, parts info, owner's/service/repair/parts/maintenance manuals etc everything totally..
I have 1987 toyota 4runner model and I keep servicing and when needed repair it on my own. worth it !!!

This is a code 46 LH Crash Sensor - Not Mounted to Vehicle Properly. Often there is a poor contact on one of the wiring connectors. Some of the problems can happen from a poor connection where everything connects under the drivers side seat.
Here is a list of codes for the airbag light issues.

Hope this helps...

Check engine light. You will need a OBD II reader to retrieve the code.
Please let me know what you found.

The air bag computer will have to be scanned and the code read to know what the fault the computer detects. The problem will have to be repaired for the light to shut off. Keep in mind, when the air bag light is illuminated the air bag system is deactivated. Meaning, in the event of a collision the bags won't deploy.

check connections at battery ,alternator ,computer input and fuses if good than have alternator and battery tested--have vehicle scanned also, some auto stores such as auto zone / advanced auto do it for free to get the trouble codes and reset codes if necessary

Around 98,000 on my 2000 Avalon, my check engine and VSC light went on. If you go to Auto Zone they could tell you the code that triggered the Check Engine light. When a sensor detects a malfunction, the engine computer turns on the Check Engine light which also disables the VCS In my case the problem was a dirty MAF mass air flow sensor which sits in the air tube between the air filter and trottle body. Two tiny screws and a disconnect to the wire and out comes the MAF. Sprints a shot of MAF cleaner, discconect your battery, reinstall MAF start her up and all was well.The key to the problem solution is finding out why the check engine light came on. If it did not come on, I would still check it for fault codes.

Seems to be a very common problem with Ford. The wiring harness beneath the drivers seat contains the sensors for the airbag system. Go under the drivers seat and secure all the wires and clips. This makes most error lights for the airbags go away. Hope this helps and good luck!

They air bag module has lost communication or in other words, cant control a SIR component.
Take your vehicle to your local Auto Zone or Advance Auto Parts and ask them to scan for codes, write the code down and respond back to me and we can go from there.
Let me know.

Yes, it's called a lamp fault code.

9 is not familiar to me. Call dealer service department and ask them what code means.

Here are codes for a 94 Aerostar. I don't have 91 Sable. Sorry.
