STO Loss 2 (STL2)
STO2–SCM2 internal loop detection error.
STO2 and SCM2 short circuit lines are not connected - Connect the short circuit lines.
After you make sure all the wiring is correct, if STL2 fault still exists after cycling the power.
Poor connection of the IO card - Check if the PIN of IO card is broken. Check if the IO card connects to the control board correctly, and if the screws are tightened well.
