E150 = No communication with the motor regulators on start-up

Is the software package on the replacement A5 card's the same as what was originally installed in the truck?
When the truck is started up the software package number is displayed for a few seconds on the dash.

The BT Reflex which this is ( just with Toyota stickers on ) has 3 different A5 software packages depending on age & none of them are interchangeable due to changes in electronic parts spec / wiring.

What year & month is the truck?

What is constantly turning?

The steer tacho on the dash OR the actual steer motor itself?
