Introduction

To complete this installation you will need to source the following:





    • 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 damage to the GO device. Some vehicles have multiple diagnostic connectors to choose from when installing a GO device.

    • For more information on Geotab harnesses and adapters, refer to the Harness Identification and Application & Harness Assessment Cheat Sheet & Geotab Truck Solution - Harness Identification and Application

    • 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 (6.5 feet), because this can 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.

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

    • An unsecure device can result in poor electric and/or data connections, which can lead to short circuits and fires or cause malfunctions of vehicle controls that can result in serious personal injury or significant damage to the vehicle. Some examples requiring professional installation from an Authorized Installer are:

    • The OBD port location is such that the device protrudes and interferes with entering or exiting the vehicle, or located where it could be inadvertently kicked or bumped during vehicle operation.

    • The device isn't fully secured and so may come loose with vibrations or accidental contact.

    • An electrical harness or additional wiring is required.

    • Vehicle mounting modifications are required to secure the device, i.e. removing of panels; deformed/damaged OBD connector; or physical damage 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.

    • WARNING! 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 collisions, leading to death or serious personal injury.

    • ! IMPORTANT: Ensure when securing the device into the vehicle, that this side is facing away from any metal surfaces.

  14. If the vehicle has a solid surface on top of fuse box. Ensure the surface is clean, and free of dust, oil etc. and attach the double sided tape of the back of our SPR-INSTALLBAG and stick it to the bracket. Apply firm pressure to it for at least 30 seconds to ensure the tape bonds correctly. Connect the other part of HRN-CW03K3 with the Go device and secure the connection of the IOX-CLAMP and the OBD interface with cable tie. Connect the white connectors of the HRN-CW03K3 with each other.

  17. Start Vehicle.

    • Start Vehicle.

    • Verify LED pattern.

    • The device emits 2 quick beeps every 60 seconds during set-up. Once all three LEDs turn solid you will hear 10 quick beeps.

    • 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.
