Vehicle diagnostics made easy: highlights of the mega macs software version 65

28-04-2022

Compatibility problems, manufacturers not available or obstacles regarding safety - vehicle diagnostics is really a hair-raising experience these days, isn't it? But so that you do not have to get too much into a flat spin unnecessarily, you have Hella Gutmann. As you know, we regularly provide our mega macs series with smart updates that will help you glide through OBD as smoothly as a hot knife through butter. Here are the highlights of software version 65:

Mercedes-Benz S-Class: Diagnosis requires DoIP and CSM

The diagnosis of the S-Class presents even hardened workshop professionals like you with special challenges. Almost all systems are secured against unauthorised access by CeBAS (Certificate-based Automotive Security) – this even includes standards such as the reading and deleting of error codes. That's why we've equipped our mega macs with a CSM (Cyber Security Management) function that authorises you to retrieve data. The next obstacle with the new Mercedes-Benz models is this: the diagnosis only works via DoIP. This communication protocol is already available in our new mega macs X. However, we also have a solution for users of the mega macs models 56 and 77: here the necessary DoIP capability can be achieved by interposing mega macs X. To do this, you only need to access the software interface of the mega macs X once.

And now there is another manufacturer on board: welcome Tesla!

The Tesla brand is considered to be one of the leading pioneers in the electric vehicle segment – by workshops but also by discerning customers. Any communication with e-cars was up till now only possible via expensive Tesla equipment. The emphasis is on "up till now": With our mega macs software version 65, you can now put the Tesla S models produced from 2012 onwards and the X models from 2015 through their paces. Thanks to the update, you have access to error codes, to the parameters of safety-relevant systems, to the data for charging control, for battery and for thermal management and also access to basic settings.

With mega macs software version 65, a diagnosis with access to error codes and parameters is possible on Tesla S and X models.

Here are the available functions in detail:

 

– Error codes with text for ESP, brake booster, adaptive cruise control, parking aid, airbag, tyre pressure monitoring, electric power steering, vehicle electrical system control unit, driver door control unit, passenger door control unit, keyless entry system, panoramic sunroof, comfort seat control unit. – Parameter view for the ESP, airbag and tyre pressure control systems – basic settings: maintenance mode for parking brake, resetting learning values for steering angle sensor, special bleeding (brake/brake fluid change), “cleaning” of the parking brake, programming of cover flap of high-voltage charging connection, locking actuator – programming high-voltage charging cable connector, unlocking airbag control unit and setting air conditioning to basic setting mode (for evacuation).

 

Testing of the cooling system is also possible.

Volkswagen Group: integration of the SFD system in mega macs software

And here’s another piece of good news for all motor mechanics: with software version 65, we have integrated the Volkswagen Group's "Vehicle Diagnostic Protection" (SFD) system into our CSM. And this is what that means for you: in future you will also be able to quickly diagnose the very latest models of several Group brands via the manufacturer portal. This is how it works: if you link your mega macs to an SFD-secured vehicle (a vehicle with diagnostics protection), it will automatically recognise this. A message appears indicating that some functions require an authorised CSM user. This person has to enter his CSM identification in order to then carry out diagnosis as usual. The process works even a little bit faster on our units with SDI user interface. Just a simple login on the device is all that it takes.

 

The following VW Group models protected by the "Vehicle Diagnostics Protection" system can be diagnosed via CSM with all mega macs devices as is usually the case:

 

Audi A3: from 2020, Q4 e-tron from 2021 Cupra: Formentor from 2020, Born from 2021 Seat: Leon from 2020 Skoda: Octavia from 2020, Enyaq from 2021 Volkswagen: Golf 8 from 2019, Caddy from 2020, ID.3 from 2020, ID.4 from 2020, Transporter T7 from 2021
