2008 Freightliner M2 won’t do force regen

Cummins ISB won’t run regen in Insite. According to Insite clutch or service brake is depressed. In JPRO it is showing the clutch pedal is depressed. Here is the kicker. It is an automatic with no clutch pedal. Any ideas?

 

Is it an Automatic or Autoshift?

 

Go to "features and parameters" in Insite and take a look at "clutch switch" parameter. See if it is "enabled"

 

In addition to this.....

Check Parameter trans setting in Insite. Set to automatic or automated.

If by chance you have a known good hook up for this truck? Or.....Just tranfer a template from a known good sister truck will fix it.

 

Truck is a Allison Automatic. I just checked and the Clutch Switch is set to "not installed". I will look for the other Transmission setting shortly. Had to pull off this one and look at another that was "hooked in". Here is a copy of what I saw this morning.

 

The transmission was set to automatic.

 

What was the reason the truck came in for service? Any other codes?

 

The regen light was on and was in limp mode.

 

Do you have Allison DOC?

 

They took it to the dealer. I work on their stuff all the time and I will see what they come up with.
