Good day everyone, I've a problem... I've here a HFM T4 VSN1 with Continental code A2C92561708 and renault code 285900636R ...
I've here original HFM and a new SECOND HAND HFM .... The colleguas say that problem is HFM becouse with original HFM car no start and no work internal central locking button instead with used second hand HFM, of couse car no start, but central locking button inside car work....
So him gived me, both HFM (Original and new second hand HFM), I've clone DFLASH and PFLASH of orginal HFM to new second hand HFM and viceversa I've exachange the file Pflash and Dflash of used HFM into new HFM...
Result car no start with new second hand HFM with (original P-FLASH and D-FLASH) need consider that both HFM have same continental code and same renault code and also pcb hardware code is all same...
This meas that problem is in the file of original HFM, infact the second hand HFM after write original data of HFM of the car lost the function of central locking.... I check ever file after write if is write ok or not and both HFM file are write OK...
Now i've restore both HFM each one with them files, and I want made virgin... I can do virgin but only by OBD with AVDI ONLINE..... And my problem is that car is at 700km about me...
I need if possible please give the second hand HFM virgin by dump (after him will go in Renault to learn with rest of car) or if have i need wiring diagram of HFM (connector A and connector B) I try to read by obd in bench and made virgin it...
Instead the original HFM I will try to change only P-flash with P-flash of second hand HFM (maybe need only reflash) without car is not easy ....
THANKS A LOT IN ADVANCED
