2015 Ram 2500 CME CM2350B intermittently displaying LPRes, DESLPres, SWBSNS and Press Solenoid Duty Cycle. All remain at 0 until SWBNS drops from 18.9v to 14v and then for a split second I get data on the pres pids. SWBNS then jumps back to 18.9. Like I said this only lasts for a split second. I don
