The PACLink Service Adaptor, created by PACCAR, plugs in to any class 5-8 truck (2005 and newer) to read engine, cab, transmission and ABS fault codes, component and gauge information. PACLink connects wirelessly via Bluetooth to your Android or iOS device with the PACLink mobile application. The mobile application is free to download in both the Google Play Store and the App Store. PACLink allows you to print and send reports collected from your truck's information. No wifi or cellular data is required to use PACLink and read your fault codes. Fault code information is collected from J1939 compatible rigs. PACLink also speaks Spanish. This device is perfect for Service Technicians, Roadside Assistance, Owner/Operators, and trucks without telematics units.
