Randy, the ECU is located under the seat below the tool holder(3 bolts and a plastic hook at the rear).
On top of the ECU is a decal with containing the ECU part number.
If the last 3 characters read J10, J11, J20, or J21 the ECU is to be replaced. If the last 3 characters read J12 or J22, the ECU does not need to be replaced.
My '14 DL1000 came with the J10, was replaced with the J12.
The last 8 characters of the VIN range for the '14 is E2100025--E2102822.
The service campaign number 2A74 for US models, 2A75 for California models.
You can call Suzuki Customer Service @ (714)-572-1490. They should be able to look up the VIN# and tell you if the campaign has been performed.
