Problem:
Subaru Outback 2023 all keys lost, Denso ECU 231300-3680. Smart pro failed, Autel IM508 failed, obdstar x300 classic G3 failed, no support. What tool and how to read on bench?
Solution:
Here is the clue.
No dealer tool will touch this and even ssm5 will not touch this.
The dealer doesn’t have a tool that will do it.
The dealer simply orders a new replacement module that’s already pre-programmed from Subaru.
It is BIU SYSTEM.
The smart key unit is integrated in the internal fuse box driver side.
But not readable till now
So you will need to order a new module preprogrammed from Subaru.
Buy a replacement module and key and steering lock then used Autel to code to the car. You don’t need the engine ECU Autel can do adoption.
All you need is the Smart ECU module, the steering lock and a working key from a donor vehicle. Same as Subaru Crosstek 2025.
The other option is at VDI abrites.
With the 850 adapter and everything you need to make it work plus their interfaces and all that stuff.
