Fellow Ram owners, recently had my Ram throw up a check engine light, lost all my sensors such as blind spot monitoring, collision both front and back and also my turn signals. It kept telling me to service my shifter. Went home and turned the engine off and then back on again and all my sensor functions where restored including turn signals but a check engine light came on. I took the ram for a trip around the block to see if would repeat the issues. Nothing, only a check engine light remains. I pulled the codes from the OBD2 and came up with these codes:
U0121 Data Bus: ABS module no communication,
P30D1 - Cylinder #1 Misfire,
U0140 - Data Bus body control module no Communication,
U0405 - invalid data received cruise control module,
U113E - Lost Communication With Intelligent Battery Sensor,
U1141 - Invalid Data or Missing Gateway,
U1186 - SCP (J1850) Invalid or Missing Data for Primary Id,
Please keep in mind no check engine lights have ever came on before and no previous indications of issues as well.

My Truck is a 2019 Ram Limited 4x4 5.7L hemi stock.

Check your battery.

Sounds like a bad battery.
