Sometimes after delete, the regen light & DEF gauge will blink (be turned on) or You will have some codes in CECU.
If You are using one of our deletes, those lights or codes will not affect engine in any way, and You can easily solve this issue with 2 pieces of black tape.

In case You don't want to use black tape method, this guide will tell You how to disabled those lights/codes in body controller.
This is applicable for Kenworth & Peterbilt vehicles with Paccar MX13 or CAT engines only.
