Field Diagnostic Tester

Use the field diagnostic tester (FDT) to verify continuity for instruments attached to the mass interconnect.

Notice To avoid damage to the FDT, do not touch bare pins on the FDT without proper electrostatic discharge (ESD) protection.
Note The FDT can only verify continuity on instruments that are included in the original ECUTS configuration shipped by NI.

Refer to the FDT-16041 Safety, Environmental, and Regulatory Information document for FDT safety information.

The FDT has three status LEDS:

  • 12 V – On when the FDT receives 12 V power from the ECUTS.
  • 24 V – On when the FDT receives 24 V power from the ECUTS.
  • ACTIVITY – Blinks when the FDT acknowledges a command from the ECU Test System Maintenance Software.
