QUICKLY diagnose tough drivability problems!


All scantools display DTCs and allow you to view PID Data. Most tools just suck out data and spit it raw, onto the scanner screen. They ignore valuable clues that help fix cars. That's because they just don't have EScan SharpshooterTM diagnostic tool box, an entire set of built-in assistants that search and interpret data. EScan is like a diagnostic compass that points you in the right diagnostic direction. For your convenience, EScan is available with corded or wireless Bluetooth interface that avoids needless cables and shop clutter. Order your EScan and start fixing cars faster—today!


The patented ATS EScan does many other remarkable things that no other scan tool can do:


     EScan Pro fuel trim chartEScan analyzes FUEL TRIM.Green squares = good fuel trim.Red or Orange squares = bad fuel trim             EScan Pro volumetric efficiency chartEScan analyzes VOLUMETRIC EFFICIENCY.Yellow and Red graph mirror each other = good..Yellow and Red graph separate = not good.


     EScan Pro catalytic efficiency screenEScan analyzes CATALYTIC EFFICIENCY. Test Cat Efficiency from idle to full throttle.              EScan Pro mode6 translation screenEScan even translates MODE6 into English. Values highlighted to indicate close to or out of spec.


(click images to enlarge)


The EScan alert lights on the left side of each screen are constantly updated and give you information on Bank 1 and Bank 2 as well as the status of the control system.


The EScan includes patented Sharpshooter Technology, which uses OBD-II data like no other scan tool ever has. When you use it in your shop it will help you verify:


• MAF Sensors Problems  • Catalytic Efficiency Problems  • Fuel Control Problems  • Fuel Delivery Problems

• Low Power Problems  • Charging System Problems  • Mechanical Problems  •  and Much More...


The EScan features:

• Very Fast Auto Connect

• Easy PID Setup plus Calculated PIDs

• Digital and Slide Bar Readouts

• Powerful Graphing

• Reading and Decoding Mode6 Data

• Recording of Data and Screen Shots

• Cursor Measurements of Charted or Recorded Data

• Reading and Decoding DTCs and Pending Codes

• Reading Freeze Frame Data

• Reading and Plotting Monitors

• Reading O2 Sensor Data

• Resetting DTCs


Get smart! Turn your laptop computer into a diagnostic powerhouse with the EScan scan tool from ATS. This Motor Top 20 Tool connects to all major data protocols: ISO-9141-2, KWP2000, J1850 (PWM and VPM), and CAN Bus Types.


Now you ask, “What makes our EScan so special?” Fair question: simple answer.


EScan is the only smart scan tool of its kind. If you aren't sure what a smart scan tool is, ask yourself these questions:


• Does your scan tool have a list of special diagnostic PIDS?

• Can your scan tool calculate and display catalyst efficiency?

• Can your scan tool tell you if the air/fuel ratio is correct: if the MAF is

   working properly?

• Does your scan tool display fuel trim charts at different engine speeds?

• Does your scan tool calculate volumetric efficiency?

• Can your scan tool translate Mode 6 data to simple English?


Those other tools just suck out data and spit it raw, onto the scanner screen. They ignore valuable clues that help fix cars.That's because they just don't have EScan Sharpshooter diagnostic tool box, an entire set of built-in assistants that search and interpret data.

  EScan Installation


Additional Update information:


EScan Download and Installation of latest version - Rev 1.31:


Quick Start Instructions:


• Download the EScan update above and save it to your “My Documents” folder.

• Double-click on the downloaded file to install the EScan. If the installer asks you if it is OK to uninstall the existing version allow it to do so and then run the Setup a second time to install the new update.

• After the update is installed, you will need to reassign the port number.

• Note that the EScan program will only run if you have the ATS EScan interface hardware connected to an OBDII port with power (Key On) unless you run it in Demo Mode.

• If you are using a non-US version of Windows, you will need to set the Regional and Language Options (in Control Panel) to use North American style comma/decimal point conversion for calculated and other values to display correctly on EScan.

• See bottom of page for driver and Windows VISTA information.
