Catalogue identity
The TuningService.uk ECU catalogue records EDC16C10 under Bosch EDC16 (catalogue record 1591, observed 10 November 2026). The catalogue name is an identification lead; it does not by itself prove vehicle fitment or software compatibility.
Application evidence
AutoTuner documents selected Toyota 1.4 D-4D applications including Yaris, Auris and Corolla.
Tuning and identification
Its cited OBD protocol describes a calibration read: check the actual backup scope, identifiers and checksum support for the tool and vehicle before writing.
Read EDC16 torque fuel and tuning basics and EDC16 variant application and tuning differences for the shared context. Examples are not an exhaustive fitment list; check the installed ECU and current tool documentation.
Additional source evidence
AutoTuner’s cited Toyota 1.4 D-4D release also names Verso, iQ and Urban Cruiser alongside Yaris, Auris and Corolla. For that release it lists MPC556 and an OBD normal read of the calibration, with tool checksum correction; these details describe the named protocol and should be checked against the current tool and exact vehicle.

Identification photograph
The label shows Bosch 0 281 013 414 and Toyota 89661-02E20. Bosch identifies the Bosch part number as EDC16C10. The handwritten C34 on the casing is not the factory ECU designation and illustrates why the label and part-number evidence matter.
