Hello, I have a problem with the parking heater in Scani r420 2007 euro 5. After turning on the stove, the fan works for five seconds and the info on the remote control pops up, heater error, then you hear beeping and the stove stops working. I checked the fuel pump and it looks like it does not get an impulse from the controller and does not give fuel. The errors that popped up are ATA 112 and ATA 120 and after moving the power plug an ATA 148 error appeared, can someone tell me what these error codes mean because I can not find. The furnace is Eberspacher Airtronic M, D4. Thank you very much
