Hill decent

[johnnypayne66]

It’s only done this one time. One day this flashed on my instrument panel.  ( hill decent ).  As far as I know this is a Manuel operation.  

 

I was braking pretty hard hard on a highway stop. 

 

Question on is I don’t think they offered that in 2014 on slt

I am not positive but I think the RPO code is JHD.

Sounds like it was powertrain grade braking not hill descent.  Hill Descent Control is button operated via a button on the dashboard and only works below 15mph.  Hill Descent is on Z71 only.

You are correct.  After searching for powertrain braking . Now that I know what it was from your statement I googled and got this.

No idea if it was offered or not, but, check the build date on the door.  Perhaps you have a late 2014 build date.
