I took my 2002 HO cummins with the 6 speed manual transmission to the dealer the to have the 3 and 6 cylinder high idle enabled . They said it was to warm to try it but said it was enabled . I've had a chance to test it in -18C, or 0F. Nothing happened after 10 minutes. I called them and they said my remote starter and alarm probably isn't letting it work. Has anyone else ran into this or heard this?

Wont work on a manual transmission

Mopar man has a manual.

Call bull on it.

They did not do it properly.

Works on auto and manuals transmissions just fine.

 

Remote starter doesn't hook to the IAT or ECT sensors. It doesn't press the brake pedal nor the throttle. So I also call BS on the dealer. You need to find a dealer that is more intelligent.

We should start a collection of the lame excuses from the Stealerships.

Im an idiot. It worked on my 02 6speed. Man im forgetting too much stuff

For me, the best one to date is:

 

" I didn't even know  Jeep  offered a diesel".      Straight from the mouth of the service manager,   Chrysler-Jeep-Dodge  dealer.    

Ya the stealership flat told me it wont work on the manuals too. I even printed out and brought in the TSB paperwork and he laughed at me and said he doesn't know what moron wrote that up. Same guy tried telling me that the PCM and ECM on these trucks is the same unit!!!

On the 3rd gens they dont work unless you ground out a wire

If it is enabled your throttle sensor might not be reading zero. Iirc... Mike had some numbers on what resistance it should read at idle... ie zero acc El pedal position.

Not voltage but the IVS has to be ground on the idle pin.

 

The throttle is true. On my 02 my apps was going bad because I could see my throttle position on my adrenaline monitor, and every once in awhile would show 1% and my high idle wouldnt work

With my DRB 3 scan tool you just go in to owner preferences ( I think thats what it says) and there is a heading to enable high idle.

You just click the yes arrow and its done.

I should be doing this for people ...bring me a coffee.

Only takes about 2 minutes and I am not "good" at it yet.

I keep telling people its super simple to enable it and that you dont flash the computer but nobody believes me

I think I should do a little slideshow of me doing this.

Could even show the high idle kit I put in thanks to Mike and Ed they are painless.

So I finally had a chance to bring the truck back to the dealer. I told them that it wasn't working and that this time I wanted to watch the technition check that it was enabled. Turns out it was not enabled. It was called 3 cylinder high idle . It made sure it was enabledthis time. I tried it out this evening and it works!! In the 6 cylinder mode anyway. It was in the garage so maybe that's why the 3 cylinder high idle never kicked in.

If the IVS switch is grounded for idle then the APPS voltage is ignored and the idle software is used. Not if the IVS is ground for Throttling then the APPS sensor voltage is used and set the engine RPM to match. All based on IVS switch depends on which leg is grounded or not.

Makes me wonder what they did the first time I brought the truck there.

I'm pretty sure the 3 cylinder mode is working to. Sounds horrible though .
