CAN-BUS GATEWAY MODULE
The R.A.SH Tronics CANbus gateway is a very powerful device, it allows access for many of the vehicle functions
without the need to remove plastic parts or additional external relays. The CANbus gateway interface with the OEM
CAN system in order to operate most of the secondary functions.
The CAN Gateway Module connects to the Drivein LCD touch screen on the LIN junction port and to the vehicle’s
CAN system to operate the secondary functions, listed below in the table. It is also responsible to wake up the touch
screen and put to sleep after locking the vehicle.
THESE SECONDARY FUNCTIONS WILL REQUIRE NO FURTHER PHYSICAL WIRING,
which will
greatly reduce the
amount of installation time and increase reliability.
There are, however, a few secondary functions that will require
physical wiring. These functions are not listed in the table below but in the pages to follow. The CAN Gateway
module is connected to the vehicle’s OBD connector located on the lower left dash panel in the driver’s area and
to the low speed CAN simultaneously. The Gateway module itself is typically installed behind the center console
area and secured to vehicle using the mounting tabs on the module. The CAN Gateway Module is responsible to
wake up and put to sleep of all system components, so be sure to connect the wires utilizing proper soldering
practices according to SAE J1292.
