1. Get a USB thumb drive. Make sure there are no other files, and especially no previous map files or folders on the drive.

2. Download the latest map file, unzip it, and move the eHorizon_Map folder to the USB thumb drive.

3. Make sure you place the "eHorizon_Map" folder is in the lowest level (root directory) of the thumb drive. Do not put it inside any subfolders or the module will not be able to find the files. 


Installing the Map Files

Once maps are on the USB thumb drive, plug it into the end of the USB cable attached to the Route Parameter Manager module. If the cable is missing or damaged, a replacement one can be ordered as Cummins Part #5394154 from your authorized dealer or distributor.  

Attach your INLINE data link adapter, launch Guidanz and connect to the Route Parameter Manager module. Several functions are available, but select the Update RPM Maps function and follow the on-screen instructions.  


If you cannot connect to the Route Parameter Manager, there may be a bus configuration issue. Some engine configurations require that Cummins Parameter Manager hardware be installed in order to access the module for service. Please refer to TSB150099 for the complete product list and compatibility charts.   

If you have issues getting the Route Parameter Manager module to read the map files, or recognize the thumb drive at all: ·
