By typing into the search field the AV list is instantly filtered to only show values that contain the text you have entered. This is a brilliant way to quickly search the list of AV’s for any ‘key words’ that you are looking for. This will narrow down the list so you can find the data that you need faster.Īnother highly useful feature that was added to the ESI 2.0 software in the 2015/2 DVD update is an ‘Actual value’ search bar. This groups parameters together and allows the technician to view either all of the supported AVs or only values connected to a particular component group or function. To help the technician select the right AV more quickly, ESI 2.0 simplifies the process by providing an ‘actual value group’ selection screen in some cases. These days, modern vehicle ECUs can support hundreds of AV parameters. The system provides a data stream which is constantly refreshing on the screen so the technician can view any changes in condition that are recognised by the ECU and visible in ESI 2.0. It is useful to understand that an AV can either be a numerical value of measurement, such as ‘Control module supply voltage: 12.9 volts’, or alternatively an input or output condition like ‘Drivers door status: Door open’.

Once you have connected the Bosch KTS to the vehicle and selected the relevant system, ESI 2.0 will offer you ‘Actual values’ in the function selection screen, if the ECU in question supports this type of data transfer. The technician can use Bosch ESI 2.0 to display the info in a variety of helpful formats and save the results for subsequent viewing and comparisons. They’re a useful representation of the state of a system at the ECU based on the data collected from the sensors or switch input signals and component outputs on the vehicle. This month we’ll explain the benefits available when you are evaluating the ‘Actual values’ of a system.Īctual values (AVs) are the variable data parameters that have been processed by the ECU and are an essential source of information for automotive system diagnosis and analysis. In the previous column we we briefly looked through the immense diagnostic capabilities that Bosch ESI 2.0 provides with the ‘SIS Trouble shooting’ functions of the tool when used with the Bosch KTS.

Because of the vast range of features available through the software, Bosch’s technical team will be breaking things down into bite-sized chunks, starting at a beginner level and progressing through to more advanced functions. This regular series of technical articles from Bosch focuses on how to get the best out of its ESI 2.0 software, which is used in conjunction with the KTS range of diagnostic tools for vehicle fault diagnosis and service function procedures. KTS diagnotics made ‘ESI’ from Robert Bosch.
