AutoLink FAQ's

What is the AutoLink? The Autolink is a plug-in replacement for the standard electronic or mechanical speed pulse module used to activate Distance Measuring Devices (DMIs). The AutoLink plugs into the OBD connector in your vehicle without the need to hard wire and connect to cables found under your vehicle.

How accurate is it? Our comparative tests indicate the AutoLink accuracy is 99.9%, or about one foot in one thousand feet. Click here to see graphs of a typical test.

How do I know if my vehicle is supported? All vehicles since 1996 have a standard connector to connect to the diagnostic computer in the vehicle. This is the OBD connector we use.

Will it work with all DMIs Yes, since all DMIs use the same type of pulses and have the same RJ11 connector.

Do I still need to calibrate the sensor? We suggest you calibrate the AutoLink sensor just like you would a regular transmissions sensor to get the best possible accuracy. If your speedometer seems pretty accurate and you don’t need the ultimate in accuracy for your application then you can skip the calibration step.

Where can I get more information or purchase an AutoLink? Currently the AutoLink is available from North Line Canada, Ltd (877-278-8342)

What is the price of the AutoLink? Pricing is very competitive with standard interface modules.?Please contact North-Line Canada Ltd.

Is your vehicle OBD compatible? If your car is a '96 or newer model, then you are fully OBD-II compliant, no worries. Just to make things complicated, there are a few cars and trucks that were made prior to 1996 that are also OBD-II compliant. Click here for a detailed list of pre-1996 cars that support OBD-II.

What is a CAN interface? There also is a new interface protocol, called CAN (Controller Area Network) that will replace the current OBD-II in four or five years. There already are a few vehicles that use this new protocol. AutoLink supports this interface as well.

Where is the OBD Connector Located in My Vehicle? The exact location of the OBD connector varies from vehicle to vehicle, but it will be within a few feet of the driver and it will have easy access.  Most often you can find your OBD connector somewhere below the steering column, either above the pedals or perhaps inside a fuse box by the driver's knee. Your OBD connector will probably be in plain view (provided you have your head where your legs would normally be while driving), but some connectors are covered. If you have trouble finding the connector in your car, check this link (click here). This document has detailed information on OBD connector locations.

How Does AutoLink Use the OBD-II Interface? One of the many parameters that you can monitor with an OBD interface is the speed of the vehicle. This is done by sending a command to request the current speed of the vehicle. This request and answer only takes a small part of a second. AutoLink sends the command for the current speed several times each second while the software is operating. The software then takes the speed reading to find the distance the vehicle has traveled. This distance is converted to pulses which are output from the AutoLink to the DMI.
