Hi everyone,

I'm looking for the CAN ID of the state of the cruise control buttons +/-  on MED17. If someone have a trick to help me to find this I would appreciate.

After research I have found a variable usually called B_canfgr but itdoesn't content state of buttons, I think it's just a condition to enable/disable fgr signals by CAN. I try to identify the variable to find the CAN associated function.

Thanks ozzy_rp Wink I already found this table but my problem is I can't find associated functions. I'm looking for functions which read/write the RAM with the CAN messages of each ID ( before an other function read/write the RAM to read/send message on CAN bus ).

I tried to make a RAM dump by CCP but I'm not able to read all RAM ( just few adress before access denied )
