PicoScope Automotive Diagnostic Oscilloscope The vehicle system analyzer in a box ALL NEW PICOSCOPE AUTOMOTIVE OSCILLOSCOPES When you buy a PicoScope Automotive Oscilloscope you get industry-leading performance that is both affordable and easy to use. With the introduction of the PicoScope 4225 and 4425, performance has been upgraded but the price remains the same! Pico automotive oscilloscopes are used by more than twenty of the world s leading vehicle manufacturers, and in thousands of workshops to save time and money by making it easier and quicker to diagnose faults. PicoScope 4225 and 4425 are the most advanced automotive PicoScopes ever, handling hybrid, electric, diesel and petrol vehicles, and can be purchased separately or as part of a kit. Faster sampling The PicoScope 4000 Series can capture up to 400 million samples per second, making them fast enough to handle CAN and even FlexRay signals. You can be sure that you will always be ready for next-generation vehicles and challenges not yet encountered. Performance and intermittent problems are revealed in great detail, and stored for later analysis. more memory The PicoScope 4225 and 4425 have eight times the memory of our previous scopes. This ensures that you can capture even more information without sacrificing sampling rates - making it easier to reveal complex intermittent faults and rare events. High input range The high ±200 V input range of the PicoScope 4225 and 4425 reduces the need for external attenuators to a minimum, and differential probes are available to handle very high voltages to 1400 V and beyond. 2 or 4 channels Up to 400 MS/s real time sample rate 20 MHz bandwidth 250,000,000 sample memory ±200 V input range Floating inputs ConnectDetect TM for reliable connections No external power supply required USB 3.0 connection for faster screen updates Protected against overloads and short circuits CAN bus and FlexRay compatible Use with any vehicle Easy to use Includes PicoScope Automotive software Free software updates 24 month warranty Free technical support Floating inputs The inputs on the PicoScope 4225 and 4425 have their own ground reference separate from USB. Each input is independent (common mode voltage up to ±30 V), increasing the flexibility and allowing you to directly measure signals such as hybrid vehicle resolver circuits. ConnectDetect TM This handy feature detects when you have made a good connection in those difficult-to-reach places, displaying the connection status on your big screen and on the front of the unit.

The main specifications explained. VerTICAL resolution The number of dots in the waveform from top to bottom. 12 bits means 4,096 dots, which is more detail than you can see on the screen all at once. PicoScope stores the extra detail for when you zoom in. Buffer MEMOry The number of dots in the waveform from left to right. If you don t have enough memory then the waveform won t show all the detail in the signal. PicoScope has more than enough memory, so you can zoom in thousands of times and still see a clear display and spot intermittent glitches. WAVEFOrm BUFFEr A memory that collects your most recent waveforms. If a waveform disappears off the screen, you can look back through the waveform buffer to find it. Trigger This ensures that the scope captures the waveform at the right time and keeps it in a stable position on the screen. PicoScope can set up the trigger automatically, but if you want you can select special trigger modes to catch unusual waveforms that you might otherwise miss. BANDWIDTH For faster signals, more bandwidth gives a more faithful reproduction of the signal shape on the screen. PicoScope has enough bandwidth to display CAN bus and FlexRay signals accurately. SAMPLINg rate Like bandwidth, this is more important for fast signals. A high sampling rate ensures that you catch the high-frequency details of the signal. Errors and omissions excepted.

CAN BUS - Intermittent ESP light Scanning fault codes on a Audi TT Quattro revealed intermittent CAN Bus errors. When the fault was present, the ESP light would go out on start-up but then illuminate as the car was driven. The CAN network was inspected using PicoScope whilst the vehicle was driven, and the captured data reviewed when the ESP warning light illuminated, showing that the CAN bus signals were incorrect. After a visual inspection of the wiring, we scoped the bus lines with the ABS ECU disconnected. As the scrambled signal was still present, we reconnected the ABS and disconnected the Haldex module on the rear diff; PicoScope displayed a good set of bus signals. As the supply and earth were confirmed as OK, the Haldex unit was replaced, and the CAN bus signals returned to normal. www.picoauto.com/tutorials/audi-can-bus.html Diesel Variable Nozzle Turbocharger After a few years of steady use of a Variable Nozzle Turbine (VNT), carbon deposits build up around the vane mechanism causing it to seize, therefore allowing boost to deviate from normal. A WPS500X was connected on the solenoid output line to measure the negative pressure applied to the turbo actuator. When the required boost level is reached, we expect the ECM to release and regulate pressure applied to the actuator whilst maintaining a suitable boost level. If however the vacuum level correctly falls yet the boost level continues to rise, then we have a problem. This test allows us to see what is happening at the end of the control circuit, and can reveal leaking solenoid valves, and blocked solenoid waste outlet. www.picoauto.com/tutorials/vnt-pressure-control.html -80mbar -640mbar -170mbar Boost sensor is forced to hit its operating limit; hence we see the signal flat-line at the top. -480mbar Over boost Normal Typical capture recorded during Wide Open Throttle (WOT) boost events. In this example of an over boost condition, the control circuit reduces applied pressure to a mere -80 mbar until boost eventually drops to normal. We can see during normal regulation the control circuit maintains a healthy -170 mbar. The proof test here is that if the turbo unit can adequately respond to -170 mbar, then it should quickly reduce boost at -80 mbar; it doesn t. More importantly, these test results determine the ECM control circuit is not contributing to this fault. Valve Timing Errors Misleading MIL An Alfa Romeo Spider 2.0L Twin Spark with MIL lamp illuminated, but no drivability issues. Reading DTCs indicated CODE 8 PHASE SENSOR CIRCUIT which cleared at KOEO, but returned when the car was started. As the auxiliary drive belt had recently been shredded, we decided to check the valve timing. This test only takes a few mintues and, with a known good capture as reference, is as effective as stripping the timing covers and visually confirming timing mark alignment. With cam and crank reference marks, PicoScope can be used on a running engine where any excessive slack can be seen as wandering. www.picoauto.com/tutorials/timing-issues.html Copyright 2014 Pico Technology Ltd.
