2011 RAM 5500 Aisin trans.
It is new to me. I got the truck with these codes (below): It runs and drives fine, just sluggish acceleration, but the turbo is stuck in 1 position, no Exhaust brake, no low rpm boost.
P0102 Mass Airflow sensor A circuit low
P0405 EGR Position Sensor circuit low
P049d EGR Position exceeded learning limit
P2509 ECM/PCM Power Input Signal intermittent
P2bacNOX Exceedance - Deactivation of EGR
U0101 Lost comm with TCM
U010c U010C-LOST COMMUNICATION WITH TURBOCHARGER/SUPERCHARGER CONTROL MODULE
What have I done? Verified fuses 21 and 37.
Waiting for better weather to continue following the U010c Factory document.
Any ideas would be great as a direction to go.
