EDC15

The workhorse diesel platform of the early 2000s. Four ident formats share the same family: A (TSW header), B (C3 fill + 1037xxxxxx SW), D (alphanumeric SW codes) and E (C167 PP22 bootstrap header).

Detection

Five checks — one exclusion pass, then four positive formats:

1. Reject if any exclusion signature is present (EDC16 / EDC17 / ME7 share the 1037xxxxxx SW prefix; Siemens PPD / SIMOS / 5WP are excluded too).
2. Format A — the TSW string at 0x8000 inside a bank. Unique to the EDC15 toolchain and the strongest anchor.
3. Format B — a 0xC3 fill ratio at or above the family threshold and a 1037xxxxxx SW string anywhere in the binary.
4. Format D — the same C3 fill ratio, plus an 0281… hardware number and an alphanumeric SW code (EB…HEX) instead of a 1037… number. Early VP37/VP44 bins.
5. Format E — a PP22..00 C167 bootstrap header in the first 64 KB, plus an 0281… HW number, plus either a 1037… SW or a structured EDC ident block. Covers C167 bins whose C3 ratio sits just below the Format B threshold.

There is no size gate. Multi-bank images are handled explicitly: a 1 MB dual-bank bin also carries TSW at 0x88000.

Checksums: no family profile (generic sweep only).
