Got my oil change today and asked them to flash the ECM with TSB 18-004-04. The Service Manager didn't know anything about it. He looked it up and told me, if it applies to my truck they can do it. Since the truck is out of the 3/36000 warranty, they said it was gonna cost me $89.00 for the flash. I went ahead asked them to flash it if it applies to my truck.

After the picking up the truck and paying for the flash, I tried the procedures to make the high idle work and it didn't. Went back in to talk to the Service Manager and he told me it may not work since the engine is not cold enough and to try it tomorrow morning. I said ok, and left hoping for the best.

I was reading a few threads about this and they may have flashed it, but didn't enable it. I guess I'll find out tomorrow morning.

And just so you guys know, I followed the procedure just like it said.

So how accurate is the statement about the high idle not being active if the engine is not cold enough?

Right
The temp. does not have anything to do with it.
They didn't enable it.

I was under the impression that this speed control idle feature was only for 2004.5 and newer 600 engines. Keep us posted if it works and I'll be taking mine in for a flash too...

When I had my non 600 flashed, the high idle did work, that was until they enabled it. BTW, don't let them tell you it's temp dependent. I use my high idle feature in the dead of summer when I'm stuck idling to prevent wet stacking.

I have the High Idle Flash on my 2004 305 555.AUTO
At first I did not think it worked.
The truck must be in park or neutral with the parking brake set.
Enable the cruise control and then press the SET button and release...it will take a half a second and will jump to 1100 RPM.
You can use the ACCEL button to bring her up to 1500 and the DECEL button to bring her back down.
Hitting the CANCEL or touching the brake will cancel it.
I am pretty sure you have to use the emergency brake.
Good luck.
P.S. I am pretty happy with this feature.

I had mine done, and it works great.
it is an early 04.
I bought it in NOV of 03.

I am not sure about the 2004 but my 2005 worked once the dealer enabled it. I can turn on cruise, press set and rpm's climb to 1100 rpm. (all without the e-brake being on) I can then adjust that rpm up to 1500 rpm by using the accel or deaccel buttons.

There is ALSO feature already enabled that will allow the motor to rev to about 1000 rpms by its own when the temps do get cold enough outside. I even have had that happen after the motor is totally warmed up and sitting still in P or N (without the e-brake on). It will auto rev to 1000 rpm. That is different then setting the Cruise Control.

As I suspected the flash didn't work. I called the SM and told him it didn't work, he said they are going to need the truck overnight to try the cold start themselves. I ask if they can just look to see if it's enabled, but he didn't go for that, he still wanted it overnight. What a PITA.

I guess I'll have to comply, nothing else I can do. I kinda understand their point of view, since I use work on an IT helpdesk. You just can't trust that the customer is actually doing everything right. But in this case, what upsets me, is that I knew more about the TSB than they did. Thanks of course to DTR.

AAAHHHH.... serenity now, serenity now, serenity now...

I'll update when I can.

Thanks for the input.

The outside temp doesn't matter with this particular TSB. You can turn it on if it's -20* or +110*. It is purely a manual feature using the cruise control buttons.

Read this TSB from top to bottom and you'll see. Then print it out and bring it to the dealer.

There's another high idel feature which will *AUTOMATICALLY TURN ON* and crank up the RPM's to 1100 if it's cold enough outside. That's probably the one the dealer is referring to.

That is not the one you want.

Like I said follow that link to the TSB, read it completely, then print it out and show the dealer.

find a different shop----It's obvious those clowns don't know squat

Gunrunner

It's a thirty second job, they dont need it overnight

Heater

I think $89 is a bit much also. When I had mine done the tech took about 15 seconds.....for free!

Toto

As Nuttymopar says....you don't need to actvate e-brake.
Tried mine last night without e-brake...worked fine.

To test the feature put the truck in park and do not put your foot on the brake. Depressing the brake pedal deactivates the high idle in preparation for you to shift to drive. Then follow the instructions in the TSB by turning the cruise on and hitting SET. When you release SET the engine should idle up to 1000 - 1100 rpm.

There is no temperature dependancy, None!

As others have posted, this high idle feature is NOT temp dependent. Obviously the SM has not read it and is confusing it with the low temp high idle that automaticly kicks in. When I had mine done (for free) I tried it out before I left the dealership. Didn't work. The Service writer had the tech come out. He had me activate it while he watched. He picked up on the fact that I was putting my foot on the brake pedal. Brake pedal or dropping the trans out of park or neutral turns it off. BTW, IMO, as this is a TSB, it should not be a warranty item even if warranty was still in effect. I had Duncan Motors in Key West do mine. The TSB is to correct a low cab heat issue. The record low temp for Key West is 45. I had to tell 'em that I visit folks up north & had the problem there. On the '04s, which is the only model this particular TSB applies to, the software change must be installed, then enabled. The '04.5 and later models already have the software, so an enable is all that is required.
