New Software Release for GE-50300-A A/C Machine Updates Leak Testing Feature

New updated software for the GE-50300-A R1234yf A/C Machine (Fig. 25) is now available to be downloaded through the Special Tools and Software Updates app in GM GlobalConnect. The software release is available for no charge to GM dealerships.

Features of the updated software include:

  • Allowing the machine to proceed with the 15% initial charge for leak testing regardless if the vehicle fails the vacuum decay test.
  • Removing the feature that forced recovery of the 15% initial charge, rebalanced the scale and then proceeded to charge the full 100% amount. To save time, the machine now holds the 15% charge in the vehicle and injects the other 85% to fill to 100%.
  • Retaining the 30-minute initial vacuum time default but changing the minimum time that can be entered from 1 minute to 10 minutes. The additional time allowance ensures sufficient vacuum time for removal of moisture from the vehicle system.
