A 10-digit number usually starting with 175 or 275 (e.g., 175800-4510 ). Visual, high-resolution bench and boot pinouts
Tools like the I/O Terminal Denso ECU Tool require direct "on-bench" wiring to the ECU’s pins to read and write flash memory without opening the case.
While Denso builds ECUs for many different brands, they share common architectural DNA, especially regarding terminal nomenclature. If you are looking at a Denso circuit board or factory service manual, you will frequently encounter these standardized abbreviations: Switched power from the EFI relay.
