Lesson 12 Specialist support for truckand off-highway vehicles

Our entry-level diagnostic tester for commercial vehicle diagnosis can be connected to the DCU 220 or a computer with the minimum specification to runESItronic 2.0* via or Bluetooth to facilitate comprehensive diagnosis, troubleshooting, fault searches and solutions to provide maintenance and service schedules for workshops (see fig 1).

Our most comprehensive and flexible solution for commercial vehicle diagnosis, KTS 900 Truck’s rugged Convertible-PC DCU 220 is a notebook and tablet in one. Boasting easy handling, rugged housing, an 11.6” touchscreen, integrated camera and dual lithium-ion batteries for an extended runtime (See fig 2).

Due to the far less standardised approach to the manufacture of commercial, agricultural, and off-highway vehicles – how and where you connect the diagnostic module to the vehicle can vary greatly between manufacturer and models. Particularly in the case of off-highway. If the vehicle in question is not equipped with 16-pin OBD-socket, there are twooptions to carry out the connection process.

Option 2 is to use a ‘direct fit’ vehicle specific adapter cable, which here at Bosch we call EasyConnect cables (see Fig. 3). This option is particularly useful when you are often dealing with a certain brand, model or system that uses a specific connector. Also, there is an additional advantage in that you do not need to switch pins manually in case you are diagnosing different systems over different communication lines. For this purpose and for your convenience, we are offering a wide range of vehicle specific EasyConnect adapter cables for all types of commercial vehicles. At the bottom of your ESI[tronic] screen, you can choose between both options by clicking on ‘Connector (F2)’ (preselected by default), or – if you do not have the specific connector (yet) – on ‘UNI adapter (F3)’. Alternatively, you can also switch between both options by pressing the F4 key.

Hopefully by now you are already familiar with the fundamental capabilities of the ESI[tronic] Evolution software. But when deployed in conjunction with a KTS Truck module, you will notice some subtle optimisations made to further enhance your workflow.

For example, vehicle selection is an even more streamlined process. Simply toggle between the vehicle type (e.g. truck or agricultural vehicle) and choose the desired manufacturer and model from the dropdown list to jump straight to the diagnosis page for that vehicle (see fig 5).

Unlike with many competitor systems, you will also have access to the ‘System Display’ as standard (see fig 6). With no hidden charges or additional subscriptions required. From here you can get an immediate understanding of actual and expected values for the different diagnoses you are working on – as well as in-depth and interactive diagrams of key elements such a wiring, gearboxes and lifter hydraulics. Just click on each component to reveal test instructions (see fig 7a & 7b).

Finally, perhaps the most unique addition to your ESI[tronic] Evolution software when used with the KTS Truck module, is the ability to customise your service based on the unique needs of niche or special-build commercial vehicles.

As previously mentioned, there is a far greater variance between the specifications of commercial vehicles. Our configurator tool enables you to build your own testing criteria based on the specific vehicle that arrives in your workshop. Simply select the relevant components from the available options in the drop-down list, click save and name your configuration to add it to your ESI[tronic] Evolution database to create a bespoke workflow for that individual vehicle, which you will be able to recall whenever you need it (see fig 8).
