EEFF500 Data Bus Fault Finder

The new Snap-on Data Bus Fault Finder (No. EEFF500) is the essential tool to diagnose Data Bus communication failures. When the Data Bus fails the scan tool loses communication with the vehicle's network of onboard computers. Technicians can waste hours searching for a computer data circuit failure. By utilizing the Data Bus Fault Finder, they can find the communication breakdown source more efficiently and solve the problem faster. 

Features and benefits include:

  • User controlled elimination of modules to isolate defects and find the failure location
  • Eliminate rogue/defective modules or data circuits that lock up the data bus via 12 switchable data channels
  • LED indicators light amber for short to ground and red for short to power
  • Self test upon power up; newer versions have a membrane switch while initial versions have toggle switches
