dss350 has that long vehicle manager, gray or black.
the current sensors are swapable but if the traction was bad and put in the lift place you should have code 6t not 2b so i don't think your current transducers are the problem, you may have a 2b code now from something being put together wrong or power cable routed through the sensor the wrong way.
have you tested the transistor modules inside the vehicle manager? tm3 and 4 are going to be worth looking at after getting 2b to go away. good luck
