A few days of normal driving will get rid of the codes.

P0603 may come up anyway, but it does all the time on its own if you fart the wrong way in the seat.
If a P1000 comes up, tell them you jumpstarted someone "last night" and disconnected the battery to clean the posts.

 

OH MY GOODNESS !!!!!!!!!

Now I have to start giving my drivers phayzyme so they'll stop "throwin codes" ?

 

I'm using the 1704 on a Feb '03 build 6.0.

You should have the latest flash loaded prior to installing the SCMT as this last flash is supposed to be about the best so far. After plugging in the SCMT and trying to load the new program, you might be asked to return to the tuner to SC for an update if the Ford factory flash is newer than what the SCMT tuner has on record in its memory.

This is normal and SC pays the shipping if you have proof of purchase.

 

This is primarily info intended to point out that there could possibly be intermittant problems with even stock trucks when disengaging the cruise control with the brake pedal.

I haven't posted earlier because it has been stated that those who have the problem (on this thread) also have the same problem when disengaging cruise with the steering wheel too.

My problem was strictly with the brake pedal; it was very intermittant; when it occured it would sometimes be repeatable for a day or too, but then may not occur again for a week.

Basically pushing the brake pedal lightly did not disengage the cruise. Pushing much harder (about 1" of travel) would disengage and the truck would have a violent abrupt deacceleration. Basically the brake switch on the pedal was defective; what would actually disengage the cruise was the brake pressure switch on the master cylinder (Ford's backup method to disengage). Dealer replaced brake switch on pedal and after about 3 weeks I believe it is repaired.

One time when it was not working I engaged the cruise at 40 MPH. I then very slowly started applying the brakes; the speed maintained 40 MPH and had just downshifted at the same time if finally disengaged. Very abrupt!

The only reason I post this is that there is a big difference between the problem posted by others if it also happens when you disengage from the steering wheel by using the off button. My 'off' button disengaged normally. I know VIC said he was near a solution with some odd hex code, IIRC. I am not trying to complicate the issue either, but as someone who solves technical problems I can't relate how many times slightly incorrect information about a problem can send someone down the incorrect path; especially if one cannot duplicate the problem and is trying to solve by studying possible issues with a program or the data acquistion. If the problem occurs with both steering wheel and brake pedal then the common item is the PCM and programming; but, if it is only via brake pedal then the situation changes. Sorry if I offend anyone by questioning the details; just trying offer some information.

BTW, I have read this entire thread; finished it sometime last year and have kept up to date.

My truck is stock, no tuner or performance mods; my only speed mod is how fast I can fill the tank to the brim!

Vic, I too appreciate your input to this thread and the site as you have offered much insight into how thinks work.

To the guy getting 18 MPG at 79-80 MPH; I'm lucky to do that holding it at 70 MPH GPS on flat ground.

 

Iam getting 17-18 with mine at 75mph on the 1704 HP tune and that is with 4" lift and 35" tires.

 

It's comin, I can feel it!

 

17-18 mpg??? That is hard for me to believe. Im getting about 15 in economy mode. But i have a hard time keeping my truck from blowing big clouds of black smoke. I tell my self today im gonna be easy on her (every truck i ever owned was a girl thats funny) but seems like i can hear her taunting me at every red light

 

As I believe Vic has stated before many people experience better mileage in HP tune than economy, but the most deciding factor is how you drive it.

When I have got 17-18 it has been on the highway empty and driven for 200-300 miles without stopping.

 

Haha!! I'm experiencing the same difficulty with black smoke, but who knows ... maybe tomorrow will be the day I go easier on the accelerator!!

My new daughter comes home from the hospital tomorrow morning, so I guess I'll be REALLY good and give her a smooth, fuel efficient ride home ... then I might have to go back out and get my "fix!"

Seriously, when I'm off the accelerator and on the highway my lie-o-meter consistently shows me mileage above 19 (with only 2500 miles on the clock), and even if you figure it's showing 2mpg high that's still exceptional. That's in Performance tune ... I still don't know if I do better this way than in Economy, but after the initial thrill wears off I'll try to do some hand calculated numbers in both modes and let you know.

The hardest part will be putting the truck back to stock next week and driving it that way for at least a week before my upcoming dealer visit...

ok guys & girls,bear with me on this. I am an atv,motorcycle & snowmobile wrench,not a novelist. Be ready to lie after programing sc back to stock when you take truck to dealer for warrenty work. I am the guy with leaky rear engine seals (2) & now new 6.0 engine & seal leaks again. My truck is an 03 F350 CC LBox singlewheel with turbo-back exh.,AFE intake,auto & SC microtuner with full autometer guages. I received my tuner after about 500 miles on new engine,tuned truck to hp mode and went for test ride with a couple of buddies(one has dodge cummins and the other has ford lightning), we turned west onto highway and throttled up,well I mashed it. next thing I know we are heading east sideways,awsome. My two buddies were screaming and laughing like a couple of 15 yr olds. CAnt say enough good about this tuner. anyway back to my problem. Took truck back to HOUSTON FORD to warrenty the rear seal leak,programmed tuner back to stock setting first, and dropped it off. The dealer said they had a ford rep comming to look at my truck. The dealer called me and asked if i had a chip in truck, i said no, then they asked me if i had a programmer on truck because they are getting a strange code. Being the honest person i am I said yes I had programmed truck. That was it,NO WARRENTY, here are there bogus reasons for the no warrenty quoted off my service invoice, (ck for oil leak ck messages road test vehical with ED from FORD monitor pids with wds ck crankcase pressure add dye to oil there isnt enough back pressure in the exh to opperate the ebp sensor at an idle or the vgt in the turbo that is why there is a lag on take off there is a code p0603 in the pcm caused by a pcm modification like a programmer call the customer to verify he is using programmer this causes to much crankcase pressure which pushes oil out of the seals clean oil off the bottom of the motor ford will not warrenty with these modifications), now Im no diesel mechanic but I know if an atv has to much crankcase pressure there are internal engine problems. I tried to talk to the ford service rep but he didnt have the time of day for me, HOUSTON FORD said the decision was final,called the FORD customer service hotline(should be called the cold line)and just got the old file a greivance line and thier decision was final. DIDNT matter I had two problems before the tuner was recieved. Had 95 psd before this truck, 300k on that truck with tuner and no leaks. $47,000.00 truck and FORD comes up with lame excuses like that. Dont know what to do from here, hope someone can give me some advice,I dont want to hire a lawyer,cost to much. Your tuner is the best bang for the buck, just letting everyone know what you need to do to get warrenty. THIS IS AN EXCELENT SITE,Im new and read the whole thing, got to rest now, my brain is full, keep up the good info. FORDFAST

 

Dealers will do anything they can to blame a failure on anything but themselves.
As you stated, the truck had the same problem bone stock!
Don't fall trap to it.
Fight.

Never tell the dealer you had a programmer (or anything, for that matter).
Truth be told, there are times where people do silly things to their cars that certainly deserve warranty denial (like my modifications list, LOL), but your case is just another example of Ford blaming their problem on you to save themselves money.

 

Oh where oh where has my super tuner gone, oh where oh where can it be? (Still waiting by mailbox).

 

Do a little more shifting from left to right foot - but, by all means, keep standing there by the mailbox. If you get cold and hungery, call Superchips Support.

 

The P0603 is a common code that comes up for no reason. I checked the codes on my '03 bone stock (about 5 min before the 1704) and it had a P0603 in it and had nothing wrong with it.

If you are using a tuner you should clear the codes and drive it a couple of days before you take it in anyways.

 

What is your ra number?
