Limp Mode after pulley install

I had a shop install the 2.85 pulley on my Hell Cat. Now we are in limp mode with the dreaded P1400 and P1645. I think the P1645 is the supercharger valve actuator. It is a diablo unlocked pcm. I read on the diablo forum that after July 10th the pcms sent by diablo will no longer throw that P1400 code. lol. That does not help everyone else as it will be stored in the bcm. At any rate my major concern now is to clear the codes on the dash and to get it out of limp mode. On the hellcat forum one member said that he did a hard disconnect of the battery and then re flashed with success. The shop is leaving the battery disconnected the entire night and will try to reflash this morning. Can any one help?

Did everything get hooked back up after the pulley swap? have you logged the SC bypass position to see what it's doing?

Thank you Jay. I will refer him to this board.

Jay, they took everything apart and put it back together again. It must of been a loose or pinched wire. Now someone needs to discover a way to get the dreaded P1400 out of the blm. I appreciate your insight.

I got rid of a p1400 on a local's 2016 hellcat. Passed dealers test and still has his warranty. I would need the car in person but it can be done.

That is great. Let me guess though. Are you back east? I did not look at your full profile. But it is good to know it can be done.


lol. Well you are far away. But on other coast. I got all the codes off on the dash. But guys on the hellcat.org forum state they are hidden where the dealer still sees them.

I'm in Wa State
