Do the S197s have gauges that do a full sweep right before startup? I heard that all 99-04 Mustangs did this but then someone said it only does it when the battery is about to fail.

How do we get the S197 gauges to do a full sweep ala European and Japanese cars?

 

i would like to know, it would be cool, though I kinda doubt it can be done, unless it's built into the speedo function

 

Reprogram the ECU to make the do a full sweep. Other than that, you are pretty much stuck as is.

Of course, why would you want our Mustangs to mimic those "other" cars???

 

Didn't the 99-04 Stang do the full sweep? I think it is kind of neat and modern. Every Ford we've owned since the 70s did the same thing w/ the instrument panel: stay still right before startup.

 

My 01 didn't do a full sweep, but I agree, it would be cool.

 

RRRoamer: Which function in the PCM controls the sweep? I have the SCT PRP so I could change most of the settings of the PCM except for those locked out by SCT for whatever reason. AFAIK there's no SCT class on instrument gauge cluster sweeps, so it should be available.

 

no mustangs do that stock.. I don't understand metro. You have an 07, why are you asking if they do the sweep thing?

 

I am asking because I would like to know if there is a way to turn on that feature. Some 99-04 Mustangs did do that prior to startup, I've seen it on YouTube and a Google search shows some discussions.

I'd like it do be different from every other Ford we've owned since the 1970s. My GT still has the green backlighting when I turn on my headlamps (no MyColor), the green backlighting for the door controls, etc... it'd be nice if it had something that was more modern, like sweeping gauges prior to startup.

 

ok. Sounds cool.. I was just a lil confused at your question..

 

Metroplex,

The problem is it isn't a parameter, so the SCT PRP can't touch it. The ECU (through the SJB) controls the instrument cluster directly. For this to work, the instrument cluster would have to be programmed with a test sweep function (assuming the cluster is reprogrammable AND you can find someone that will can and will write an updated firmware for it with the needed function) AND the ECU would have to be reprogrammed to send a message to the cluster do the test sweep at startup.

Fundamentally, this would be pretty trivial for Ford to implement as they have all the source code to all the electronics in this car. For anyone else without that source code, it would be a REAL PITA. Not saying it can't be done, but it won't be easy and it won't be cheap.

 

Thanks RRRoamer. That makes sense, Ford likes to cut costs and cut out the lines of code for Global Windows and didn't program the sweep function. I'll never understand why they try their hardest to kill the fine details on their cars.

 

They didn't cut out the lines of code for the Global Windows. They deactivated that feature after the 2005 run due to owners stating windows were automatically rolling down on their own. Mine have never done that when I was away from the car, however the odd time when I go to roll them up they do roll back down immediately, not 10 minutes later like several people claim they did.

 

thats happened to me a few times too

 

That's never happened to me in the 07. I read somewhere on TMS that it wasn't possible to re-activate on 06-up S197s, but I'd like a fully functional global windows feature because it is a convenience.

 

Yeah. The global windows thing was one thing I was very much looking forward to. And yes, they DID remove the code for this. Up until about April 2005, the code was still there, but the function was disabled. After that, the code was removed and it was NOT possible to reactive it.

I know. My car was made in late March 2005 and I investigated this throughly "back in the day". Global windows was actually the one function I REALLY wanted on my car. I was PISSED when I found that it had been deleted.

Of course, looking back, the one feature I would TRULY miss if it was removed is the express up/down on both windows!!!! I don't know HOW many new cars I have driven and ended up cussing at the windows when they WOULDN'T GO ALL THE WAY UP!!!! That is such a simple, cheap thing to implement that I REALLY don't understand why it isn't standard on all makes and models. Your talking about 10 lines of code and maybe $0.10 extra for the switch (in million lot size quantities).

But, I know a guy that bought a new truck a couple years ago and actually got manual windows...

 

One other thing. The whole point of the test sweep is, well, to test each gauge. They very well may have a better system built into the gauge cluster so they don't NEED to do a sweep to detect a failed gauge...

Or they just might not have thought of it...

 

umm. wouldn't you also know as soon as you started or moved that a gauge was not working too?

 

not necessarily, the other gauges (not speedo or tach) may only go to their normal positions, but could possibly not go any further

 

Plus, you are then assuming people are actually paying attention.... Right......

 

true, think about it. What do you think of the chance of that actually happening? 1 in a 50,000??
