High idle switch

[Tony Gibbs]

I can't seem to get my switch to work. I just left a friend and the local dodge house and he varied that the high idle was on. What do I do to get it to work?

[Mopar1973Man]

What version of switch do you have? Does the switch solder to a printed circuit board or do the wires come right out of the back of the switch?

[Tony Gibbs]

I have the solder I bought it straight from this sight earlier this year within the last 4 months

Can you go into more detail in regards to how you are using it?  

 

Any codes?

 

Do you have a live data tool to read the sensor data for IAT and ECT?

[Mopar1973Man]

Yeah, that's a current version setup. Also looks like it's in good condition.

 

Typically you toggle the mode BEFORE you start. So select 3 CYL or 6CYL for cold start. Then start the truck as normal. It should rise up in RPM within 5 minutes typically. It will not instantly rise up there is a period of time before the idle rises. It will step up slowly in about 100-150 RPM bumps till it reaches 1,200 RPM. 

 

3 CYL will not work if the coolant temp is above 140*F already.

 

6 CYL should work at any coolant temperature. 

 

If the high idle software isn't enabled it will not engage high idle no matter how long you wait... A lot of people have issues with a Dodge Dealer and getting the high idle enable correctly. Smarty tuner is the easiest just flash a tune then flash back to stock.

Do you have a live data tool to read the sensor data for the truck?  that's the easiest way to know if the switch is working or not.  

 

 

[Tony Gibbs]

Yes I have a snap on computer I will let you know something I'm 20 minutes 

[Me78569]

We need to know IAT and ECT in all positions of the switch

[Tony Gibbs]

That was with it on 6cyl I didn't get 3cyl

[Mopar1973Man]

So that is 6 CYL mode. So that means the high idle software is NOT enabled.

[Tony Gibbs]

Ok. That's what I was afraid of. I will see if I can remedy the situation and let y'all know.

I am pretty sure that you can rent a smarty from DAP for not too much money.

I took my truck to the dealer to have the computer flashed and the idle software turned on.  My switch didn't work so I went back and had them do it again.  It turns out they had done everything right the first time except turn the idle option on.
