Special Tools Software Update Download Process

The Active Fuel Injector Tester (AFIT), R1234yf A/C Machine, Pico Scope NVH Tool, and TPMS and RF Tool are just a few of the special service tools that require occasional software updates in order to ensure the tool functions properly, offers the latest features, and is applicable to new GM models and systems.

To perform a search for a software update on the special service tools website, search for the parent tool number for the hardware, not the software update number. For example, EL-50334-100A (Multimedia Interface Tester hardware), not the software item number, such as EL-50334-SW2. The software item number will not be found via keyword search.

To download the update, click the software link listed for the hardware and follow the instructions.

Always refer to the Update Instructions found under the list of Support Documents for more information, if available. (Fig. 16) The Update Instructions cover the steps that should be taken before as well as during the update process to avoid any errors and properly update the tool.

Links to the user guides for the tools also are provided.

  1. Update the software only on the GE-50300-A. The GE-50300 should not be updated.

  2. Rodney Halsten says:

    Be careful about the R1234YF machine. There are two software versions. One for the GE-50300 AND THE GE-50300-A. If you do not know this you will put the “A” software into the non “A” machine and then your machine will set high pressure failure messages and no longer operate. This will require a high dollar service visit from your Robinaire dealer to repair. Please make a note of this. Thank you.
