Snap-on Data Bus Fault Finder

Today’s vehicles have 15 to 20 computers talking to each other on shared circuits that can ultimately fail. The new Data Bus Fault Finder (EEFF500) from Snap-on 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. The 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; via membrane switch or toggle switches; 12 standard banana jacks for DMM probing; Communicates via data bus network connector; Bus integrity LEDs that constantly monitor the Data Bus; and a two-year warranty.
