truck kicks into high idle

Nope, no lights if it does it automatically...only if you initiate one manually.(or at least that what I was told)

 

It was my understanding the MaxxFarce was programmed to automatically kick into high idle when the computer sensed the engine was running too cold.

 

My Volvo will do an automatic parked regen when idling. Doesn't show any lights and the only way you notice is the idle speed kicks up from 700 to 1100 or so.

 

If it shows hot exhaust temp it's a regen. It won't necessarily show the regen light but you can tell by the sound and the high idle

 

Volvos would show "Regen in progress" on the drivers information center, but the regen needed light wouldn't be on.

 

Either regening like the Volvos do. Or it could be set up that way to keep the oil running through the motor because those maxxforce run high oil pressure in just cruising speeds.

 

Cruise control on?
Hitting resume will turn on high idle,for times when you want to build air pressure.
