IOX-COLD troubleshooting

This section guides Partners through the troubleshooting process for issues related to IOX-COLD.

Identify the issue

Before contacting Support, please attempt to identify whether the issue is hardware or application related. The issue is hardware related if there is a problem with the IOX-COLD. The issue is application related if there is a problem with MyGeotab.

Gather the information

Before troubleshooting, please follow the steps below to gather all the necessary information related to the issue:

Hardware-related issues

If the issue is hardware related, follow these steps:

Record the information of any hardware that is currently in use:

GO device serial number (12 characters, visible on the device, starts with G),
IOX-COLD serial number,
Tachograph model and version, and
Make, model, year, and VIN of the associated vehicle.
etc.

Check for connectivity and installation issues:

Check to ensure that the device is securely mounted and installed according to Installation Instructions.
Take note of IOX-COLD status indicator blinks and refer to IOX-COLD/IOX-COLD RUGGED Troubleshooting Matrix.

✱ NOTE: Regardless of hardware issues, always make sure to check each and every connection, including harnesses and/or the IOX, as applicable. The vast majority of issues result from loose or insecure connections.

For more detailed troubleshooting steps, see the section on Troubleshooting the Issue.

Application-related issues

If the issue is MyGeotab-related, please contact Support. Before doing so, record the following information:

Database name,
GO device serial number (12 characters, visible on the device, starts with G),
IOX-COLD serial number,
Tachograph model and version, and
Make, model, year and VIN of the vehicle in which the hardware is installed.

Troubleshoot the issue

Once basic information is collected, please refer to the IOX-COLD/IOX-COLD RUGGED Troubleshooting Matrix for more detailed troubleshooting steps. Some issues may require advanced troubleshooting. If your issue is not listed or solved with the proposed solutions, please contact Support. The IOX-COLD device has a status LED that produces a series of blinks followed by a pause. The first blink corresponds to the first row of the matrix, the second blink corresponds to the second row, and so on. Ensure the ignition is ON when checking the installation status. If the LED is OFF, it could be due to a power problem or a device failure. Check if the GO device LEDs are on. If so, check that the IOX harness is correctly plugged to the GO Device. It could be a power issue with the GO device.

✱ NOTE: If the problem is not resolved, repeat the installation with another IOX-COLD. If the problem persists, please contact Support.

Important Safety Information and Limitations of Use

WARNING! Do not attempt to install, configure or remove any product from any 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 units while being operated could cause malfunctions or accidents, leading to death or serious personal injury.

WARNING! All in-vehicle devices and related cabling must be securely fastened and kept clear of all vehicle controls, including gas, brake and clutch pedals. You must inspect devices and cabling on a regular basis to ensure all devices and cabling continue to be securely attached. Loose cabling or devices may impede the use of vehicle controls, resulting in unanticipated acceleration, braking or other loss of vehicle control, which could lead to death or serious personal injury. Improperly fastened in-vehicle devices may detach and impact operators upon sudden acceleration or deceleration, which may cause injury.

WARNING! 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.

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

WARNING! Do not attempt to remove the devices from the vehicle they were originally installed in for installation in another vehicle. Not all vehicles share compatibility, and doing so may cause 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 death or serious injury and/or vehicle damage.

NOTICE: 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.
