JLTV: Update MSD for Best Performance


Warfighters, when it comes to the maintenance support device (MSD) for your JLTV, you’ll want to make sure it has the latest software and firmware versions.
        
The wireless AT-platform test set (WATS) and the DS Viper must have the correct software and firmware versions in order to pull diagnostic codes from the JLTV.
        
The latest or most current firmware version of DS Viper is 1.4.1.17 and the most current firmware version for the WATS device is 1.5.5.0. However, the instructions that follow should be applied whenever new versions are released to ensure your MSD and JLTV are always mission-ready.
        
DS Viper can be downloaded from CM Tool and copied to your MSD-V4 computers via CD-media with the CD drive that’s included in the MSD-V4 kit. Updating the DS Viper software requires admin privileges. If you don’t have admin privileges, seek out your ISSO.
        
Once DS Viper is installed, then the WATS firmware can be updated using DS Vipers’ WATS firmware updater tool. Here’s the CM Tool link and it’s CAC-enabled:
