Failed to connect to Body Computer

Post by ThreshNL » 12 Sep 2018, 13:38

Hi all,

I'm trying to connect with my Fiat Grande Punto T-Jet (2008) in order to activate cruise control. However, i can't connect to the car. All the COM ports are fully functional but i still get the message "Failed to connect to Body Computer" when i try to connect. What am i doing wrong?

-ELM327
-Multiecuscan 4.2 REGISTERED

Thanks in advance,

Usually if you can connect to the engine but not other modules, than your ELM has bad termination resistor on CAN line. After removing (and even better: adding proper termination), it should work.

Only if you have FTDI USB IC in it and PIC microcontroller.
Cheap fake chinese clones are totally useless.
