Ford v series visteon

[alexics]

Has anyone any information on the KEYCODE DUMP output on the earlier m series Visteons? Is it simply a keypad code dump or the radio code being dumped. Any idea how to enable this output?

[alexics]

The test points for this KEYCODE DUMP in the service manual are labeled PHONE, FLASH_CD, TELE_MODE and BLUETOOTH which makes absolutely no sense at all. Any ideas or am I just talking garbage?

Could this be front panel button press combos????

Just discovered that at one point in the eeprom progression in the eeprom data you can read the code directly out of the eeprom. I have run a sequence of 50 changes through a v series Visteon and I am now examining why I can read the code at this point. It seems that the encryption reaches a point where it is not encrypted at all. However you would not know this unless you already know the code.

The code for the set under test is 9469. The code pattern found is 2F 47 F7 D2 97 55 92 08 27 01 53 88. The hex value for the code is 24FD.

[2]F [4]7 [F]7 [D]2 97 55 92 08 27 01 53 88

Why would F772 have any significance? In decimal it is 63346.

thanks

Is this a progressive sequence? For an unencrypted code the first digit cannot be greater than two. Your have:

[F]7 [1]0 [9]2 [9]5 etc

Each time the set operates this key sequence changes so it is a case of switching the set on, dumping it, switching it off and repeating until enough sequences are captured. If the power to the set is under computer control the process could be automated.

Something about the sequence I posted earlier holds the key to the decryption. I am investigating.

F7 10 92 95 ...F4 69 65 80 ...35 2B F3 49 code 5781 ok :shot:

The hex for 5781 is 1695. The key to decrypt must be in the processor.

thought this is sussposed to be an Inglish speaking forum.
