GM-LAN Single-wire CAN

How work with CAN-Hacker and GMLAN 

We’ve found an old Oplel instrument cluster in our car service and tryied to connect with it.

We used CAN-Hacker Baby but you can use CAN-Hacker-3.0. For connect to the GMLAN you need:

  1. Connect a CAN-Low line from CAN-Hacker to the GND
  2. Connect a CAN-High line from CAN-Hacker to the GMLAN
  3. Set 10kbit/s in the Settings->CAN-Baudrate. CAN-Hacker will understand 10 like 33.333 kbit/s

For cluster ON, you should send this message:

ID=0x170  DLC=3   DATA = 0x55 0x55 0x55
