Where to look
In rough order of how little work each option takes on a Fiat DAIICHI unit.
- 01
Chassis label
Slide the unit out and read the label on the top face. Look for DAIICHI in the small print and a seven-digit serial, sometimes preceded by SN.
- 02
Rear connector shroud
Ducato units repeat the serial on a sticker beside the ISO connector at the back, which is readable once the unit is half out.
We can turn it into the 4-digit unlock code
Optional — this guide stays free either way. If you would rather not chase the code down yourself, enter the serial and we return the digits straight away.
Entering the code
However you got the four digits, this is how they go in.
- 1
Ignition on; the display shows CODE.
- 2
Enter each digit with preset buttons 1 to 4.
- 3
Hold preset 6 to submit.
Tips from the workbench
Alfa and Lancia badged units of the same generation use the same DAIICHI serial format — pick this product for those too.
