Thanks for the info ...
I have voltmeters & ohm meters and am ok at troubleshooting electrical
circuits, however I have no clue as to what wires to check.
The Haynes manual I purchased is of no apparent help ...
Where might I find the 'forward crash sensor'?
Look either on the firewall or front radiator support for a little metal
box with an arrow facing forward. Take it off and check connections.
CLean the metal around where the box mounts to make a good ground.
The last time i had 9 blinks on my Taurus it took a replacement air bag
diagnostic module to fix.
If your working on the bags, disconnect the battery and wait an hour
before you start connecting and disconnecting things to be safe.
The older air bag units had a back up supply that would power the bags
You will NOT find air bag info in an after market manual. The factory
shop manual is the only place to get any information. Look on Ebay.
I have a brake warning light that does not work (another post) ...
This further indicates an electrical problem ... I suppose I could have
a connector loose ???
I just had the instruments out and checked all the bulbs, so I just
replugged the connectors on the back of the instruments.
I haven't a clue as to where all the stuff is for the air bags ... not
even the 'electronic diagnostic monitor' that it mentioned.
The Haynes manual warned me to disconnect the battery when working on
the dash ... so I did.
Speaking of manuals.
There are 3 important manuals for your car. A quick Ebay search for "1991 Ford
Manual" and "1991 EVTM" came up with these.
1. 7973060172 and 7973456554 are Body\Chassis\Electrical and Powertrain manuals
will have diag information on the SRS system. This is the basic "shop" manual.
2. You would also benefit from an Electrical\Vacuum Troubleshooting Manual,
EVTM, which has wiring diagrams, component locations, and switch pinout tests.
don't appear to be any on Ebay right now for your CV. The 1992 EVTM should be
close for everything except the engine, here's one: 7972764090.
3. 6960028839 is an Engine\Emissions Diagnosis manual, also called Volume H.
information for finding drivability concerns, etc. Contains trouble code charts
pinpoint tests along with a lot of other info.
If you plan to keep the car, these 3 manuals are the best money you can spend
your car. That's assuming you plan to do your own work.
Greed. That fellow always starts his manuals at 39.99, and they usually don't
$40 isn't really bad though, an original from Helm is ~$150. I just put that one
reply because it was there on Ebay.
My most urgent problem is understanding and resolving the problem with
the blinking air bag light.
At the moment, I have not located even located the 'forward crash
sensor' or the 'airbag diagnostic module'!
I am an electrical engineer ... NOT a automobile mechanic ... I have
rebuilt a couple transmissions, one engine, and tinkered a lot ... my
expertise in electronics.
I work well from schematics, etc.
Is there a particular book that I should concentrate on getting? If we
keep the car, I plan on getting all three +

Start with the Body\Chassis\Electrical manual. It contains all of the info on
SRS except the wiring diagram. Take the plastic panel between the header panel
(grille) and the radiator. IIRC the foreword crash sensor is down in there
I did a quick look this evening but did not see anything in the area
around the radiator that looked like any kind of sensor.
I did find a round plastic box(approx 3" dia by approx 2" deep)located
on the top center of the firewall ... with a single wire coming from it
... not sure what it is ?? Someone said that the sensor would have a
arrow on it pointing forward ... did not see any arrow.
