Engines and their ECUs
| Engine | Engine codes | ECU family | Model code |
|---|---|---|---|
| 2.5 4-cyl | A25A-FKS | Denso Gen3 (Renesas R7F7012xx, RH850) | |
| 2.5 hybrid / plug-in | A25A-FXS | Denso Gen3 (Renesas R7F7012xx, RH850) |
The model code is the family-level part of the label (for example 89661-06X91). A donor must match the full number, which we confirm against your VIN for free before you buy.
Clone the RAV4 / RAV4 Hybrid / Prime ECU — $350 flat
Mail your original and a donor with the same full part number. VIN, immobilizer data, coding and adaptations are copied across on the bench, typically within 24 hours of arrival. Factory immobilizer stays on.
Toyota / Lexus / Scion engine ECU cloneOn-car software step — remote Techstream, $250
Some cars still want an on-car step after a module swap — an ECU communication ID registration on a smart-key car, a calibration update, or a key registration. Plug a J2534 pass-thru interface into the car and we run the factory Techstream software on it from our bench — no dealer visit. The same session covers programming after any other Toyota or Lexus module replacement.

Which engine ECU does a 2019–2026 RAV4 / RAV4 Hybrid / Prime have?
It depends on the engine. The 2.5 4-cyl (A25A-FKS) runs Denso Gen3 (Renesas R7F7012xx, RH850), model code 89661-0R or 89661-42. The 2.5 hybrid / plug-in (A25A-FXS) runs Denso Gen3 (Renesas R7F7012xx, RH850), model code 89661-0R. The label on your module settles it in seconds.
Can you clone the ECU on a RAV4 / RAV4 Hybrid / Prime XA50 (TNGA)?
Yes, with a label check first. This generation runs the newest controllers; some read and clone on the bench, some need the on-car route. Text us the label and VIN and we tell you which before you pay. The clone is $350 flat.
Will a cloned RAV4 / RAV4 Hybrid / Prime ECU need dealer adaptation?
Usually not — it leaves the bench carrying your VIN, immobilizer data, coding and adaptations. If the car still asks for an on-car step, we run it remotely with Techstream over your J2534 interface for $250.
