ECM Module
Dual Mode connects to the engine computer and will transmit the data it receives to the client’s database. There is also a
3 axis accelerometer that is used to detect vibration and is also use for collision detection and accident reconstruction.
As with all engine diagnostic devices, there is a need to be programmed for the exact year make and model of vehicle it is
going to be installed into. If not correctly programmed, the device can negatively affect the operation of the vehicle.
Hardware Included
The Dual Mode module can be installed on the GEOTrac 5800
(discontinued but still supported) and the GEOTrac 5530. Contact
sales@geotracinternational.com for more information.

Installation Procedure
Follow the installation guide and training for the GEOTrac 5800 or GEOTrac 5530 including the Peripheral Harness.
Because of the vibration and collision detection features the ECM must be mounted firmly to either the frame or firewall of
the vehicle it’s being installed into. Each ECM is mounted to a metal plate that will allow you to screw or bolt the ECM
solidly to any flat surface inside the vehicle.
Light duty vehicle connection
The ECM is shipped preprogrammed for the specific year, make
and model of light duty vehicle you are installing. Please be sure
to double check the unit number and programming prior to
install.
The ECM is shipped with a right angle OBDII connector that will
be plugged into engine diagnostics port on the vehicle. This is
usually on the drivers’ side, below the steering wheel and to the
left side.
Once connected to the vehicle port, run the cable to the
mounting location of the ECM module and connect to the port
marked “VEHICLE”. This will the side that has only one port. Be
sure to tighten down the screws to avoid accidental disconnections.
