Still don't understand what the wrench light is for what do I do to fix it

The maintenance service indicator notifies the driver when the next service is due. Approximately one month before the maintenance service is due, the type of maintenance is indicated in the speedometer display. If one large wrench is shown, a minor service (A) is due. Conversely, if two small wrenches are shown, a major service (B) is due. The value shown in the display may reflect the calculated distance (in miles) or time (in days) remaining. When the maintenance service term has been exceeded, this value is preceded by a "-" (minus symbol).

That's impossible to know without reading codes an doing diagnostic's to find the problem . At least 1 hour diagnostic time . What's your local repair shop charge for that ? The chevy dealer near me costs $ 86.30 an hour . This is in PA .

Just rusted or stuck? A shot pf Liquid Wrench or PB Blaster and then lightly oil it. don

There is probably a scanner which can diagnose this. It would be more elaborate than the 100-200 dollar units.

There is a sensor which prevents the transmission from shifting into final drive until the engine warms up. Could be the wrench light is telling you that it is missing this signal or the signal values do not match specs.

Check your owners manual for a description of icon. May indicate some type of specific service is suggested. The Amber lite is usually an alert. Red lite would indicate repair needed. Once you understand description if you need more assistance, please refine your question. Every bit of info is helpful.

Hey pisces63 sorry if this shows up twice, im not seeing my question when i asked under comment, but would you please help me to understand where and what the minute and wrench buttons are? thank you.

That wrench is a maintenance minder indicator lettting you know that your oil's service life is at 15%, not that the level or amount is low. Have your oil changed and have the maintenance minder light reset.

This is the anti theft security system failing. I'm sorry I don't have a good way to fix it, but this is an informative link to help you understand what is going on. http://vatspasslockpasskeysecurityhelp.yolasite.com/

Service (Wrench) System Check The SERVICE (Wrench) telltale is turned ON by the cluster when it receives a command from the powertrain control module (PCM) or the body control module (BCM). The PCM or BCM will turn the SERVICE (Wrench) telltale ON for all non-emission related diagnostic trouble codes (DTCs) that require that a telltale be turned ON, some DTCs do not turn ON a telltale but are stored to aid in diagnosis.
The SERVICE (Wrench) telltale will also be turned ON if the Antilock Brake System (ABS) control module has detected a fault in its own warning indicator system. If the ABS cannot turn ON its own telltale, a message will be sent to the BCM through the Key Word 2000 data bus to turn ON the SERVICE (Wrench) telltale.
The SERVICE (Wrench) telltale will be turned ON by the cluster for 2-3 seconds, when the ignition is turned to RUN, for a visual system check.

You need to have codes checked .

I have a 2004 LS V8 & do all my own work

I can understand the battery failed as it was
more than 4 or 5 years old

The converters would have had to be damaged
in the accident if something got under the car
& damaged the exhaust pipes,no other reason

The Gas Pedal is called a Electronic Throttle
Control Module,I'm looking at my wiring diagrams
for a V6 &v8. I don't see that as an issue

The Throttle Body is almost always replaced at a dealer
& seldom an issue either. Reason --When you have a really
bad COP Ignition Coil it spikes your PCM & the signal
comes back on the TPS Sensor on the throttle body &
the pcm looses throttle plate % & starts to cut out
fuel injectors

Bottom line ,not many people like working on Ford Products
& the dealer will really cost you dearly & with negative results.

I have seen many codes related to coils & never more than
one bad one,while it could happen

It sounds as though 80% of your issues have nothing to do
with the accident.

We own one of the most complicated vehicles out there
It has Jaguar Technolgy as well

I don't know if any testing or diagnosing was done on your car
or if what was done invloved a body shop,then off the a dealer
or local repair shop,but I don't get a warm fuzzy fealing on anything
but the battery

As long as your wrench is light you have codes to at least look at

The ETC Failsafe on the right bottom side if dash is a BAD COIL
as I explained above. You will drive up to 22 miles in hot weather

The PCM you can see & feel under & behind the glove box
To remove it you have to remove the box on pass side of engine
compartment that covers the Cabin Filter as the 2 harness connectors
ar there down low

I doubt the PCM Failed

Go to a local shop that likes lincolns & just have them find
the one bad ignition coil.
them it will only go 6 mph in failsafe. Unusable for now
