QuickCheck is a hand-held portable device that connects to your Cummins ECM. It can transfer ‘hot specs,’ read fault codes and engine data, direct engine edits, and trim or enable electronic engine features.

The QuickCheck user manuals are installed in PowerSpec under C:\ProgramData\Cummins\QuickCheck

Note: the QC5100 and QC5200 handhelds are no longer sold; however, firmware upgrades for these devices are still available by installing the latest version of PowerSpec PC. Legacy products QuickCheck I, II, and III are no longer supported.

For more information on PowerSpec, please visit the PowerSpec website.

QuickCheck is set for obsolescence. 

Our last batch of supplies for the QuickCheck Kit (part number 5298640) may last until June and with that, we are ending this product line. This is primarily being done because the capabilities are already available in our existing diagnostic software, specifically, Cummins INSITETM when paired with a Cummins INLINETM datalink adapter. 

PowerSpec software users can use Cummins INLINE datalink adapters to communicate to on-highway Electronic Control Modules on CMI products.

To purchase the replacement products, please contact your local Cummins Distributor. To find your local Distributor click here.

Software Licensing

Some Cummins software and mobile applications – including INSITE™, Guidanz®, PowerSpec and QuickCheck – require unique software licenses for use. Licenses are available through a Cummins-authorized distributor or dealer. Please provide us a few details to find your local representative.
