SCAN TOOL DATA INTERPRETATION AND OSCILLOSCOPE FUNDAMENTALS
Scan tool data can be a real time saver when you know what you’re looking at. This session will look at key pieces of data including Fuel trims and Mass Air Flow sensors, that should be checked on every vehicle, focusing on some fundamental operations such as fuel trims and plausibility tests of common sensors.
Unfortunately scan tool data can often be limited, or even lie with default numbers substituted in when a fault is present. This is where an oscilloscope becomes an invaluable tool to go right to the source and look at sensor and actuator operation in real time, with a proper sample rate far superior to a scan tool or multimeter. This session aimed at the beginner to novice oscilloscope user will illustrate just how simple these tools can be to use and interpret, boosting your workshop productivity.
