RE:
CPX-930 Software Update
TIN NO.
TIN-19-00-002
AFFECTED VEHICLES: All models and model years
PURPOSE
MMNA recently launched an all new battery and electrical diagnostic analyzer, Midtronics CPX-930, and
cloud-based Battery Management Information System (BMIS).
Due to the wireless connectivity at some or our dealerships, and the software update recovery
methodology incorporated into the new Midtronics battery tester, the over-the-air update functionality
has been less than stable.
To ensure every new battery tester has the most current software update, as a temporary
countermeasure, Midtronics will be sending every dealer that is NOT on the current software
configuration (192-111588C) a thumb drive and USB adaptor to manually update your unit. The update
package will be sent to the Service Manager’s attention on Thursday, 4/25/2019.
Please update your unit as soon as you receive the update package – instructions are included below.
Midtronics will also be removing software update 192-111588C from the BMIS hosting site to
temporarily eliminate the reminder to update your tool over the air.
Please retain the thumb drive and USB adaptor for future use – one more software update is
forthcoming that will include a more robust update recovery method. This update is expected to be
available in mid-summer.
NOTE: Dealers currently at software configuration 192-111588C are at the current software
configuration number and will not be sent this update package.
To check your software configuration number, from the main menu:
1. Select version
2. Check the “config” number
If you have any questions, please contact Midtronics Customer Service: 1-866-592-8052.

9. Once the update completes the tool will reset
and bring the user to the first screen in the
setup process. Unplug the USB and Micro USB
adapter. Save the Micro USB adapter for
future updates.

Initial Setup is complete, the CPX is ready for

Troubleshooting
Error: Ensure CPX is docked or connect to a battery
higher than 11V.
1. The CPX should be firmly seated into the
docking station.
2. The CPX should not be removed from the
docking station during the update.
3. Make sure the power supply is plugged into an
appropriate outlet and the barrel connector is
firmly inserted into the docking station.
• To check the power supply, use a multimeter and test for 12V on the power
supply barrel connector. If 12V is not
present, a new power supply is required
for the docking station.
4. Inspect the charging pins in the base of the
docking station and the charging connections
on the bottom of the CPX. Pins should depress
easily and charging connections should be
clean and free of debris.
• Using a multi-meter, test for 12V on the
charging pins. If 12V is not present a new
docking station is required.
5. If power supply and docking station are
working properly and this error continues, call
Technical Support (information below).
6. If connected to a battery, check battery
voltage and ensure it is greater than 11V.
