Those other tools just suck out data and spit it raw, onto the scanner screen. ► Can your scan tool translate Mode 6 data to simple English? ► Does your scan tool calculate volumetric efficiency? ► Does your scan tool display fuel trim charts at different engine speeds? ► Can your scan tool tell you if the air/fuel ratio is correct: if the MAF is ► Can your scan tool calculate and display catalyst efficiency? ► Does your scan tool have a list of special diagnostic PIDS? If you aren’t sure what a smart scan tool is, ask yourself these questions: eSCAN is the only smart scan tool of its kind. Now you ask, “What makes our eSCAN so special?” Fair question: simple answer. This Motor Top 20 Tool connects to all major data protocols: ISO-9141-2, KWP2000, J1850 (PWM and VPM), and CAN Bus Types. Get smart! Turn your laptop computer into a diagnostic powerhouse with the eSCAN scan tool from ATS. ► Low Power Problems ► Charging System Problems ► Mechanical Problems ► and Much More… ► MAF Sensors Problems ►Catalytic Efficiency Problems ► Fuel Control Problems ► Fuel Delivery Problems When you use it in your shop it will help you verify: The eSCAN includes patented Sharpshooter Technology, which uses OBD-II data like no other scan tool ever has. 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. ► Reading and Decoding DTCs and Pending Codes Using this test saves time since we do not have to remove any AF or O2 sensors and perform a back pressure test.► Cursor Measurements of Charted or Recorded Data The frequency on the yellow graph indicates a clog in the exhaust system such as a clogged catalytic converter. The 2005 Subaru Forester: a test of the Mass Air Flow (MAF) sensor using the ATS EScan uncovered the problem. In this case the Prius showed GREEN cat at idle and 1500 RPM but at 2000 it turned RED with 53 cat eff %. When the value for Catalyst Efficiency % changes to RED this indicates a problem with the cat. The screen below shows the test being run at idle with 96 cat eff %. The Prius: when running a Cat Eff test, the GREEN indicates the cat's capability of reduction and oxidation is good. In this article Jerry Truglia uses both to simplify the analysis of a P0420 on a Toyota Prius and detect a driveability problem on a 2005 Subaru Forester.

Catalyst Efficiency % and Volumetric Efficiency are two tests made quicker and easier with the ATS EScan.
