Hey ONELLY23,
Did you end up resolving this issue I am having the exact same symptoms with the lights on, radiator fan and ac fan, wipers not working ect. This issue came up while I was driving and caused the gauge cluster to go haywire, felt like it was in limp mode as the shift from 1st to 2nd was a little rough - I checked my codes: U1000 P1212 P1610 P1612 P0462 U1001
U1000 Can Communication Error
P1212 TCS Circuit
P1610 Immobilizer Lock Mode
P1612 Communication between ECU & Imm.
P0462 Fuel lvl sensor
U1001 Can Communication Circuit
Did cleaning the ECM ground work for you here? Did you get an immobilizer code thrown too?
