Introduction

This guide describes how to install a IOX-COLD & GO device into a vehicle with a Tachograph.

    • 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 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 (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.

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

    • Ensure you use enough cable ties to secure both the device and the harness to the vehicle. 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 could protrude or interfere when 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 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, such as removing of panels. The OBD connector has been deformed/damaged or there is 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. Any installation, configuration, or removal must be done only in stationary vehicles that are securely parked.

  4. Before installing, record the following:

    • Before installing, record the following:

    • GO device serial number (located above the barcode on the device label)

    • Odometer reading

    • Vehicle or asset name

    • VIN (vehicle identification number)

  5. Locate the diagnostic port in the vehicle Start removing the dash panels required to access the vehicle’s diagnostic port. Take care not to damage any plastic clips or misplace any screws. Depending on the vehicle, the amount of disassembly can vary.

    • Start removing the dash panels required to access the vehicle’s diagnostic port. Take care not to damage any plastic clips or misplace any screws.

    • Depending on the vehicle, the amount of disassembly can vary.

  6. Remove the necessary dash panels in order to route the tachograph harness from the tachograph mounting location to the GO device. In this example we need to go from passenger side of the vehicle, across the dash, and up the driver's a-pillar.

  8. Locate the Thacograph in the cab of the vehicle. Usually it is located above drivers head. Using the correct tool, remove the tachograph from its mounting location.

    • Locate the Thacograph in the cab of the vehicle.

    • Usually it is located above drivers head.

    • Using the correct tool, remove the tachograph from its mounting location.

    • Pull firmly on both sides at the same time.

  9. Some tachograph units are protected with a security seal that must be removed to proceed with the installation. Remove the brown and red connectors. Plug the brown and red tachograph harness connectors into the tachograph until they lock into place.

    • Remove the brown and red connectors.

    • Plug the brown and red tachograph harness connectors into the tachograph until they lock into place.

    • Connect the factory brown and red connectors to the matching female connectors on the tachograph harness. Ensure both connectors are locked into place.

  10. Route the HRN-URTACHO02-A harness from the Tachograph mounting location over to the diagnostic port location. Use cable ties to secure the harness. Ensure to avoid or stay behind any airbags that may be located in the vehicle’s a-pillar.

    • Route the HRN-URTACHO02-A harness from the Tachograph mounting location over to the diagnostic port location.

    • Use cable ties to secure the harness.

    • Ensure to avoid or stay behind any airbags that may be located in the vehicle’s a-pillar.

    • Trim any excess cable tie.

  11. Using a digital multimeter, measure the resistance on the CAN wires which are located on pins 5 and 7 on the red connector. Ensure the ignition of the vehicle is off. If the resistance reading is close to 60 ohms, this is correct. Any other resistance reading will require you to cut the pink wire loop on the HRN tachograph harness.
