Security Access Denied

Post by Mobi74 »

Good morning, after a ABS change (the whell FR and BL was stuk) the brake is working fine, but the immobilizer block me to start the engine, by the function "RFA Remote Keyless Entry and Start Programming" for realign all the board I get a "Security Access Denied", so I can't go forward, someone have some advice for a possible solution?


My car is a ford cmax 2017 1.5 tdi, my software tools is forscan 2.4.22 paied with a new and original Vliker FS (from amazon), the new ABS is F1FC-2C405-AF and the old is a F1FC-2C405-BG

Thanks

It would help a lot if you told us what car you are working on ...and what type of tools you are using !!! :roll: ...As we don't have a crystal ball !

I think the problem was the driver door and the rear door open, when I have made a try with all the door close, the service have worked, now I can turn on the engine.
Thaks to forscan
