Has anyone had code P04DB pop up after installation? If you have how did you fix it? I disconnected the JB4 and the code hasn’t returned. This truck is pretty much stock

Did you unplug the jb4 from the sensor? If so check the pins/connections. Make sure theres no damage to the wiring harness. If all physical connections are good on the sensors check the jb4 itself for any damage if nothing is wrong then you might want to get in contact with BMS. -
For install issues, please contact [email protected]
Thank you!Burger Motorsports
