NASHVILLE, TN – Cummins is expanding its suite of digital tools, with apps that offer quicker and easier access to engine fault codes and more.

Anyone with an iOS or Android smartphone or tablet can use the cloud-based Guidanz app to read fault codes and other information about engines built since Model Year 2007. When paired with an INLINE mini Bluetooth adaptor – plugged directly into a standard J1939-13 interface — it generates prioritized data that can be emailed to an operations manager or service provider. If service is required, the app also offers an online service locator to find a certified repair site. Even when it’s offline, the system can provide a list of engine faults.

The Guidanz interfaceCertified service providers, meanwhile, can dig deeper into the Immediate Assessment feature to improve shop scheduling. Once the engine is in a service area, they can pull a full fault code report, repair time estimates, and the parts that will likely be needed. Work orders can begin before the truck enters the service bay.

Guidanz will be available in April through the Apple App Store or Google Play Store. The INLINE mini and Intermediate Assessment feature is available through Cummins.

Meanwhile, the Connected Advisor telematics system gives engine owners information analyzed by engine experts who report on critical and non-critical issues, helping fleet managers to decide when service should be scheduled.

Recommendations are prioritized and based on time, helping to tell the difference between immediate and pending repairs. Daily fault reports, including probable causes and recommended actions, help to initiate the repairs. But immediate notice comes if a fault requires prompt attention.

Connected Diagnostics customers can purchase Connected Advisor, helping to further interpret engine issues with time-to-service recommendations.

Cummins has also introduced Connected Software Updates, which offer over-the-air programming through telematics providers. Software updates come through the Connected Solutions portal, giving fleets a tool to upgrade individual engines or all eligible engines, or even pre-approve updates automatically.

Original software is stored in the Engine Control Module when updates are loaded. If there are any problems, that is the version restored in the Electronic Control Module.

“We’re working through fault code recommendations for a variety of our products back to 2013,” says Chad Pruitt, service engineering director.
