PicoScope Automotive Active Diagnostics and PicoBNC+

A PicoScope such as the brand new 4425A or 4225A from Pico Technology in the UK, is at the heart of one of the most advanced automotive diagnostic systems available and, in short, diagnoses problems with automotive electrics, electronics, mechanics, NVH and Pressure.

Despite its outstanding specifications and abilities, PicoScope is reasonably priced and easy to use because it has been developed over more than twenty years and is used world-wide. It is available in Southern Africa from Garage Lube, which is a company based in Sandton, Gauteng.

Our new, free, online Maths Channel Course is being uploaded and the first five lessons are now available. Maths Channels is a powerful yet under-utilised PicoScope feature - it is like having a free scope upgrade with lots of extra and useful channels.

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.

First of all, in order to use the Automotive PicoScope, 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 PicoScope Automotive Diagnostics Kits. These money-saving Kits contain everything you need so please consider the 4225A 2-Channel or 4425A 4-Channel Starter Kits or one of the more advanced kits, rather than purchasing the oscilloscope on its own.

Diesel Engines and Hydraulics

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 PicoScope 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.

Features and Benefits

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 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.
