Denso 175822-887 — an ECU for Toyota, Lexus, Mazda and Subaru on the Renesas SH/RH850 core. After a calibration edit the firmware checksum must be recalculated.
This unit is found on дизельных и бензиновых vehicles Toyota (2005–2016) — a total of 8 models, among them Toyota Commuter, Toyota Dyna 150, Toyota Hiace, Toyota Hilux, Toyota Land Cruiser Prado.
Recalculation is needed after any calibration edit — Stage 1, Stage 2, DPF off, EGR off, AdBlue/SCR off, DTC removal, Flap off, Lambda off, Speed limiter off, Torque monitor off, Hot start fix: the checksum no longer matches, and the ECU throws an error or refuses the firmware.
Upload the modified file (MOD) and the original (ORI) — the tool compares them, finds the affected regions and recalculates only the required checksums, leaving the rest of the calibration untouched. The result is ready in a second and free; downloading the fixed .bin requires registration in the portal.
Other checksum plugins from the same manufacturer — open any of them to recalculate the checksum.
