DO I NEED A SCOPE OR A SCAN TOOL The short answer is ‘both’, but read on... PicoScope oscilloscopes are not designed to replace scan tools. Scan tools and scopes do very different jobs, so a well-equipped workshop needs both. Here’s how a typical PicoScope diagnosis works: 1. Read the fault report or listen to the customer’s story. 2. Test the vehicle until you see the problem for yourself. 3. If the MIL is on, use a scan tool to look for fault codes (DTCs). 4. If the DTCs point to a faulty component, use PicoScope to check that the component really is faulty before replacing it. 5.If the...

PICOSCOPE 6 A WIDE RANGE OF DIAGNOSTIC TESTS SEE MORE DETAIL FOR LONGER PicoScope 6 is our latest PC Oscilloscope software. Supplied with all Pico Technology Diagnostics Kits, the PicoScope Automotive software is a powerful tool for capturing and viewing waveforms from almost any electrical or electronic system in today’s motor vehicles. PicoScope can sample at high speeds, letting you capture fast-moving signals like FlexRay, CAN and LIN bus lines. Equipped with a deep ‘Always on’ memory, PicoScope enables you to capture long sequences to check for missing or distorted pulses over a whole...

The result is a kit that is used by independent garages, vehicle manufacturers and dealer networks all over the world. FIND INTERMITTENT FAULTS...

Case Study: Misfire on a Toyota Avensis Diagnosed with the PicoScope oscilloscope software. The MIL light was on, and the fault code reader showed: P0171 and P0174: System Too Lean on banks 1 and 2. The short-term fuel trims were up to 18% and 19%, also suggesting a problem. PicoScope showed a glitch in the O2 (red and blue) and MAF (green) sensors when the throttle was snapped open. Here we can see that the MAF sensor (now blue) had a low peak output of less than 3.5 V, and both O2 sensors remained lean throughout the wide-open throttle test. On inspection, the MAF sensor elements turned...
