FAQ
What devices do I need to install to use the services offered by Jaltest Telematics?
What is FMS?
The acronym FMS stands for “Fleet Management System”. It is a standard interface to
access data of commercial vehicles (truck and bus). In 2002, six large European
manufacturers decided to develop this standard: DAF, Daimler AG, IVECO, MAN,
VOLVO/RENAULT and SCANIA. The FMS standard gathers a series of data transmitted
through the J1939 protocol, combining the access to tachograph data among others.
This was the origin of a universal information and communication source.
Which information depends on FMS?
In its basic version, Jaltest Telematics offers a series of data obtained from the FMS bus
(or equivalent). These data are the source of data for the following reports: idle time,
speed report, RPM, consumption, brake use, inertia, distance travelled, and some
sections of the efficient driving calculation.
Does my vehicle have FMS?
Any vehicle equipped with FMS has a specific connector established by the FMS
standard. Depending on the brand and model, its location will be different. Our
technical department will confirm if your vehicle is equipped with it or not. In case your
vehicle does not have FMS, we will suggest an alternative to have access to the maximum
amount of information by connecting through an equivalent CAN bus.
Which data can I obtain through remote diagnostics?
Remote diagnostics enables the connection with all electronic control units (ECUs) present in the vehicle that have coverage in Jaltest. This connection allows the reading of diagnostics errors, classifying them as “present” or “non-present. For each error, the additional information related to the errors registered by the ECUs at the moment of the error occurrence is also gathered. This information is very useful to analyse the
conditions under which the error occurred.
In addition, each control unit has a set of data that identify it and a group of measurements that allow the user to know and evaluate the correct operation of the control unit and, therefore, the correct operation of the vehicle. Some examples of these measurements are: brake pads wearing level, percentage of dirt in the fuel filter, date
of the next oil maintenance depending on the usage conditions, fuel pump pressure…
The access to this information opens the door for an improvement that had not been
contemplated before in the context of conventional telematics solutions, promoting the desired concept of preventive maintenance and alarms based on the real vehicle
operating status.
What is a digital tachograph?
A digital tachograph is a control device whose ultimate purpose is the same as the
purpose of the analogue tachograph. The difference is that it registers information
related to the activity of the vehicle and its drivers digitally in an internal memory of
the tachograph and of the driver card. This way, the traditional chart discs are replaced
by smart driver cards.
