Video Overview

    • WARNING! Only use Geotab telematics devices with Geotab-approved harnesses acquired from Geotab-authorized channels. Use of non-Geotab harnesses from unauthorized channels can cause serious safety risks, including fire, and can lead to serious personal injury and/or damage to the vehicle.

    • IMPORTANT: Always use a vehicle-specific harness when offered by Geotab or the vehicle manufacturer to avoid possible GO device damage. Some vehicles have multiple diagnostic connectors to choose from when installing a GO device.

    • For more information on Geotab harnesses and adapters, see Harness Identification and Application & Harness Assessment Cheat Sheet GUIDE V2.0

    • If a longer length is required to facilitate installation, connect a straight harness to a T-harness. Ensure that the total harness length does not exceed 2 meters (or 6.5 feet). Any two harnesses that exceed 2 meters may compromise the integrity of the data and cause issues with the vehicle’s Engine Control Unit (ECU).

    • For more details on compliance information and applicable products, contact your Authorized Reseller.

    • Some installations are not straightforward and must be completed by an Authorized Installer to ensure a secure installation.

    • Ensure to use many cable ties to secure both the device and harness to the vehicle. An unsecure device installation can result in poor electric and/or data connections that can lead to short circuits and fires or cause malfunctions of vehicle controls that can result in serious personal injury or significant damage to your vehicle.

    • Some examples requiring professional installation from an Authorized Installer are:

    • The OBD port location is such that the device could protrude or interfere when entering or exiting the vehicle, or located where it can be inadvertently kicked or bumped during vehicle operation. The device isn't fully secured and so may be able to vibrate loose or get kicked or knocked. An electrical harness or additional wiring is required.

    • Vehicle mounting modifications are required to secure the device i.e. removing of panels, or the OBD connector has been deformed/damaged or there is any physical damage visible to the electrical wiring.

    • The device does not power on and beep six times when first installed.

    • The installer questions their ability to complete a secure installation according to these instructions.

    • Do not attempt to install, reconfigure or remove any product from a vehicle while the vehicle is in motion or otherwise in operation. All installation, configuration or removal must be done only in stationary vehicles which are securely parked.

    • Attempting to service devices while the vehicle is in motion could result in malfunctions or accidents, leading to death or serious personal injury.

    • As seen in this compatibility graphic, the HRN-DM09T2 harness is backward compatible with Type 1 (black 9 pin) equipped vehicles as well as newer Type 2 (green).

    • Older Type 1 (black) diagnostic harnesses should not be reused with Type 2 (green) vehicles as they are not compatible.

  8. Unfasten the OEM 9 pin connector from where its mounted.
    • Unfasten the OEM 9 pin connector from where its mounted.

    • Pull connector and harness aside to make it available for connection later.

    • NOTE: US customers need to attach the Geotab CARB EO identification label sticker next to their Vehicle Emissions Control Information label which can be found inside the engine compartment (Light Duty vehicles) or on the drivers door jamb (Heavy Duty vehicles).

    • ! IMPORTANT: USA Only: Place the enclosed CARB Executive Order (EO) identification label sticker somewhere near the Vehicle Emission Control Information label on a smooth and clean surface.

    • The EO identification label is required to aid inspection of the vehicle under the California Smog Check program and other applicable smog test programs. See here for more info.

    • All in-vehicle devices and related cabling must be securely fastened and kept clear of all vehicle controls, airbags, and gas, brake and clutch pedals.

    • This requires the use of a cable tie when securing the device or any extension harness to the OBD connector, securing both sides of the harness. If you do not use a cable tie, vibration in the vehicle can lead to a loose connection which could cause the vehicle’s engine computer to fail, causing potential loss of vehicle control and serious injury.

    • Inspect devices and cabling regularly to ensure all devices and cabling continue to be securely attached.

    • If at any point after an in-vehicle device is installed a warning light illuminates on the vehicle dash or the vehicle stalls or has a marked drop in performance, shut off the engine, remove the device, and contact your reseller. Continuing to operate a vehicle with these symptoms can cause loss of vehicle control, and serious injury.

    • Your in-vehicle devices must be kept clear of debris, water and other environmental contaminants. Failure to do so may result in units malfunctioning or short-circuiting, which can lead to a fire hazard and cause loss or serious injury.

    • Do not attempt to remove the devices from the vehicle in which they are originally installed for installation in another vehicle.

    • Not all vehicles share compatibility, and doing so may result in unexpected interactions with your vehicle, including sudden loss of power or shutdown of the vehicle’s engine while in operation or cause your vehicle to operate poorly or erratically and cause serious injury and/or vehicle damage.

    • This product does not contain any user-serviceable parts. Configuration, servicing, and repairs must only be made by an authorized reseller or installer. Unauthorized servicing of these products will void your product warranty.
