high idle via cruise control for '04 manual with pin #22 grounded and ECM flashed ?

[verk]

Hi forum. I feel bad asking this question because there are so many threads about it, but having spent time looking on this forum and dieseltruckresource I'm still not sure whether this works on my truck. My engine has a serial number and date of manufacture that meet TSB 18-004-04 requirements, but has a manual transmission. I recently grounded pin #22 of C2 connector and the ECM was flashed for this sometime ago by dealer. Does anybody out there with a '04 ( pre '4.5 ) manual have this working ?

It also has to be enabled AND activated in the ECU using a DRB or comparable tool. If your truck meets the parameters of the TSB then it should work if it is enabled and activated.

Tried to get this working on my 04 years ago. Finally gave up. All hoops jumped through but no joy.

I would double check that it is indeed activated and you have a good ground.

Didn't know about distinction between "activation" and "enabling.", thanks cerberusiam. S.Morris did your truck otherwise meet the criteria ( i.e. engine serial number < 57130284 and date of engine manufacture before December 10, 2003 ) ? Ground is good, but certainly possible the dealer didn't activate, thanks AH64ID.

While at dealer this morning for airbag recall, I had them check the state of cruise high Idle (TSB 18-004-04). It was not enabled, so they enabled it, but it still doesn't work. The dealership thought they were dealing with the high idle that comes on automatically when engine cold so I'm not confident they did the right thing. If somebody has a programmer in my area and is willing to meetup to try please pm me.

I beleive it must be a 325hp to work not the 305 or 250

Resurrecting this thread hoping that somebody with '04 manual ( manufactured before 12/03 ) can confirm they have high idle ( i.e. ability to choose idle speed via the cruise buttons ) working. I've grounded pin #22 and been the dealer sometime ago, but it never worked. Now I'm considering buying HP Tuner programmer/tuner and think it might allow me to get high idle working if the hardware supports it.

 

[Bob4x4]

As I stated in an earlier post It needs to be a 325 version to work

Thanks for reply. According to this thread, multiple 305/555 people have it working. My truck came without cruise control, but adding the steering wheel controls cruise just worked. Maybe this has something to do with ECM thinking this truck doesn't have cruise. Only been 13+ years, I'll figure this out eventually.

Only works on automatic transmission.(03-04) I wish it wasn't so, but like you I have tried, but given up on the idea.

No, it works on 04's also if the ECM is in the correct range and it has the correct flash level on it. Manual trucks are easier because they are all speed control not CC and the type of CC was the real issue. IIRC, with the oval CC buttons it will never work seamlessly thru the ECM, the square buttons should work if it has been activated, turned on and the correct ECM\flash level is there. Every truck delivered after Dec 10 2003 had the software in it to do the idle up feature so it wasn't just 325 engines. Getting the correct ECM number, flash level, the sequence of activated and on, and with the manual the ground wire was the problem. It is entirely possible that function is bad in the ECU also, a 13 year old truck can have all manner of things not working in the ECM while not impacting its primary functions.

i was told you have to have the newer steering wheel for it to work. and as for a flash, a smarty will do it. flash it to whatever Catcher Tune you want, start truck, then flash back to stock and it's enabled. but only with the newer wheel. i lucked out and have the auto.
if asking a dealer for help, ask them to enable the PTO function.
After market shop that would be installing a PTO devise could help you as well.

Wow, this is the most detailed answer I've yet seen on this question. I've never seen any mention of the style of CC buttons. I've attached a photo of the CC below if you or somebody else can identify. I still have the receipt for these steering wheel controls which I added after I bought the truck. Cruise worked when I connected them. I'll post CC part numbers tomorrow to hopefully clarify for the future.

 

[Killer223]

That's the correct ones. The old style are round.

Seems to make sense with what cerberusiam posted. Is it the wheel or the controls on the wheel? I have to imagine the clock spring the same regardless of steering wheel so perhaps it has something to do with the PCI message generated on J1850 VPW bus by the CC buttons. Thanks for informative replies.

 

[cerberusiam]

Those are the new style buttons and with a manual it is speed control so it should work.

Note that it may require a DRB III to activate the idle up feature because I think they removed a lot of stuff in the StarScan and Witech tools.

If you would post the build date and ECU number so I can check something. I think the instructions are also missing a step if you don't flash to the latest revision, there is another step I think around the PTO that needs done in older versions.

Photos of details below...

If I'm reading correctly, build date is 11-17-03 and engine number is 57121205 which meets criteria. Since these cruise switches have been identified as correct versions I looked up the part numbers in case others need to retrofit: 56049378-AA and 56049379-AA.

Now for the mistake, the ECM part number is 3957300 which I'm now realizing needs to be flashed according to this TSB. This would explain why the dealership tried to activate/enable without success. I don't know how I missed this previously, sorry for confusion. So it is possible to still have high idle if I get the ECM reflashed ? What is simplest way to realize ( e.g. dealer, programmer ) ?

Thank you

 

[Killer223]

know anyone with a smarty? see if anyone on the forums close to you might have one, there was a "rental" program a while back.
That's all you'll need to enable the function.

 

[cerberusiam]

Yeah, your build date and engine number is before the cutoff but the ECM Ref # is in the range that will accept the flash. I thought you said you had it flashed but if not then that is why it won't work, you have to have the correct software revision for it to work as speed control. If you have never had the ECU updated to the latest revision then that is the missing link.
