INTERCHANGEABLE PART NUMBERS
This module is 100% compatible with modules bearing any of the following Part Numbers:
| HARDWARE CODE(S): | EFI-MA39C, D1L1 |
|---|---|
| INTERCHANGE PART(S): | F1ZF-12A650-BB, F4FF-12A650-JB |
| HOLLANDER PART NUMBER | N/A |
UNDERSTANDING PART NUMBERS:
01
The last two alpha characters in module part numbers refer only to the date of manufacture and are completely interchangeable with each other.
02
The presence or absence of a leading zero as the first character in the part number is not significant. It may appear on your old module with or without a leading zero.
03
If your old module, or one recommended by a dealership, begins with “RL” this simply means that the original manufacturer had “rebuilt” your old module, or that the dealer only offers OEM-rebuilt module instead of the original which may no longer be available. In these cases they have merely replaced the first 2 numeric digits in the part number with “RL”, meaning “rebuilt”, with no actual functional difference.
04
Your old module may show a “P”, or “P/N” in front of the part number. This is merely a field heading on the sticker that means “Part Number” and is not significant
