Mobile B2B diagnostic support

Diagnostic support for the jobs
that slow your shop down.

Mobile sublet diagnostics, electrical testing, network analysis, and programming support to help your team resolve complex cases, protect bay time, and complete repairs efficiently.

Shop-partner communication

Clear communication from diagnosis through repair.

5volts.ace works alongside your service team as a diagnostic and programming resource. Test results, recommendations, and next steps are communicated through your designated contact so the job stays organized and everyone remains informed.

  • Diagnostic findings and recommended next steps are documented for the service advisor, owner, or designated contact.
  • Customer questions are coordinated with the shop to maintain clear and consistent communication.
  • Previous repairs are evaluated objectively based on current test results and vehicle condition.
  • Additional testing or work is performed only after the shop approves the expanded scope.
