PicoScope Automotive Diagnostics

A PicoScope is not and doesn't replace a scanner or OBD tool. It works with your scan tool to help you find the real cause of a problem. There are many Scan Tools available, which all rely on the vehicle's ECUs (Electronic Control Units) to produce a fault code that shows the general location of a problem.

What if the ECU or CAN bus is faulty, can you rely on a fault code? What if the fault code can be as a result of many different problems, do you swap components until the problem goes away? This can be very expensive, especially when components code themselves to the vehicle when they are installed.

Using your PicoScope in conjunction with your Scan Tool, solves many of these problems. Typically, you would:

  • Start with a Scan Tool to find the location of the fault (fault codes);
  • Then use your PicoScope to test the components and trace the real cause of the problem;
  • Repair or replace the component you have verified is faulty;
  • Retest using your PicoScope to ensure that the cause of the problem has been eliminated;
  • Use your Scan Tool to clear the Fault Code; and
  • Finally, use your Scan Tool to check that the Fault Code does not recur.

Active Diagnostics and PicoBNC+™

An oscilloscope, such as the latest PicoScope 4225A, 4425A or 4823 from Pico Technology in the UK, is at the heart of one of the most advanced automotive diagnostic systems available. It is able to diagnose automotive electric, electronic, mechanical, NVH and pressure problems.

Despite its outstanding quality, specifications and abilities, Pico products are well-priced and easy to use. It has been developed over more than twenty years and is used world-wide.

PicoScope Automotive App

Pico have released their App which is available on Apple's App Store and on Google Play. Scan the codes or search for PicoScope.

The App provides an introduction to your diagnostic journey. It explains using videos, animations, short descriptions and images what PicoScope is, how to use it and how it can make your workshop much more efficient and profitable. Use the App to find out what oscilloscope diagnostics are, how to get started, understand waveforms and decide which kit is best for you. See some real life applications and enjoy training videos.

Pico will be updating and improving the App and you will always be kept up-to-date with the latest information. We hope you enjoy using the App and please let us know if you have any comments or questions.

Worldwide Chip Shortage

There is a severe shortage of integrated circuits and this has adversely affected the electronics and automotive industries worlwide. Sadly, this includes the production of PicoScopes. The 2-Channel 4225 and 4225A PicoScopes are currently unavailable and consequently, all 2-Channel Kits have been withdrawn at present.

The 4-Channel 4425A and the 8-Channel 4823 PicoScopes are available but quantities are limited. The 4-Channel Scopes on their own, the Starter Kits and the Diagnostic Kits are also currently unavailable.

The 4-Channel and 8-Channel Kits including the Professional, Standard, Advanced, Master, Diesel, EV and Vehicle Assessors' Kits are all available at present. However, delivery / lead times have been extended. If you are contemplating purchasing a PicoScope, please don't delay and contact us if you have any questions or concerns.

Popular PicoScope Kits

There are a number of kits available. A selection of the most popular is shown below. The Standard Kit is a great entry level kit. You can start using you PicoScope immediately and purchase further accessories later as you need them. The Diesel kit is, as the name implies, best for diesel vehicles. There are longer test leads for larger vehicles. Ignition testsing components in the Standard Kit are replaced with items more suitable for diesel testing. The EV kit is for testing Electric Vehicles and charging systems. Safety is paramount because of the dangerous, high voltages present on EVs. There is also Standard Kit to EV Kit upgrade available.

Automotive Oscilloscopes

An Automotive PicoScope turns your laptop or desktop PC into a powerful diagnostic tool as a result, you can think of it as the X-ray machine of diagnostics. It lets you see the changing signals inside wires.

In order to use the Automotive Scope, you will need a PC and some test leads to connect to the vehicle. As a result, most people purchase one of the award-winning Pico Automotive Diagnostics Kits. These money-saving Kits contain everything you need so please consider the 4425A 4-Channel Standard Kit or one of the more advanced kits such as the EV Kit or the 8-Channel 4823 Professional Kit, rather than purchasing the oscilloscope on its own.

PicoScope Diesel Engines and Hydraulics Kit

Your PicoScope is well suited to diagnosing problems in both Diesel and Petrol Engines. A Diesel Kit is available with longer leads to help with large vehicles.

By combining the high-precision hydraulic transducers with a Pico Automotive Kit, you can use the Engine and Hydraulics Kit look at hydraulic pressures in the same time frame as the engine control signals. Consequently, you have complete visibility of how the system is operating. You can now see the exact moment valves start to move in the hydraulic system and compare this directly to the relevant electronic controls. Additionally, you can investigate stalling and 'no start' conditions due to the comprehensive coverage of engine and electrical systems.

What is an Automotive Oscilloscope?

An oscilloscope (scope) such as the 4425A, 4225A and 4823 is a simple device that draws a graph of a value (e.g. voltage, current, pressure, sound) vs time. The PicoScope is a storage scope so it draws the graph (actually up to four at the same time) and remembers it. Consequently, you can study what happened after the event occurs.

Learn more about how scopes work with our free, on-line, introductory training courses and also, watch some of our videos to see the scope in operation.

Software - No Subscriptions

PicoScope software is free and no subscriptions are required to download up-to-date versions. There are two current releases, PicoScope 6 which is the stable, production release and PicoScope 7 which will eventually replace PicoScope 6 but is currently being tested. You can download both versions and try them even if you don't have a PicoScope yet. PicoScope Software

Features and Benefits of PicoScope

Measure and test most of the electrical and electronic components and circuits in any modern vehicle including:

  • Batteries, alternators and starter motors
  • CAN bus, LIN bus and FlexRay
  • Compression, Vacuum and Fuel
  • Electronic throttle control
  • Ignition (primary and secondary)
  • Injectors and fuel pumps
  • Lambda, airflow, ABS and MAP sensors
  • Starter and charging circuits
  • Noise Vibration and Harshness
  • Hydraulics

For the technician, a 4425A or a 4225A PicoScope leads to faster, more efficient diagnostics and above all, a better understanding of how vehicle systems work.

  • Eliminate guesswork and test individual components before they are replaced.
  • Find intermittent wiring and connector faults.
  • Solve a problem where no code has been set or when multiple or misleading codes have been set.
  • Investigate charging and starting problems.
  • Resolve problems with actuators such as motors and injectors including those not monitored by the ECU.
  • Identify mechanical problems such as compression and slipped or incorrectly fitted timing belts.
  • Hunt down Noise, Vibration and Harshness (NVH) problems.
The WPS500X Pressure Sensor Kit can be used with the 4225A and the 4425A
