Creating a buzz

All-makes tool from Delphi

Published:  26 February, 2014

This all-makes tool connects to the common rail injector whilst on or off the vehicle to run an electronic diagnosis and is designed to complement the sealed rail kit and false actuator kit. Once connected, the Buzz Tool measures the resistance/inductance of the injector coil, checks the insulation of the coil to the injector body and drives the valve to make it 'buzz'. The tool is supplied with a set of eight adaptors for the whole range of known CR solenoid injectors.

  • VIDEO: 100 years of innovation 

    Vehicle technology has advanced dramatically over the past century and Delphi has seen many changes during its time in business, with many developments coming from the company itself. Here is an overview of the last 100 years, compressed into 180 seconds.

  • New sensors 

    Blue Print's engine management range has nearly 1,050 part numbers for around 5,500 applications and includes camshaft position sensors, knock sensors, MAP sensors, oxygen sensors and many more. New additions include a camshaft position sensor for the Suzuki Jimny, Swift and Wagon, a throttle body for the Daewoo and Chevrolet Matiz, a knock sensor for the Toyota Auris, Prius, Yaris and other models as well as a crankshaft angle sensor for the Kia Rio 1.3i.

  • Onwards and upwards 

    A new research and development facility opens in Coventry for XTool Europe to support its UK and European distributor network. The team of software engineers will use the new premises to develop its range of car and commercial diagnostic tools. Managing director Andrew Dimond says: "We wanted to create a static location that our software engineers could work from allowing a smoother work flow. Previously they would work from our Cheltenham office but it quickly became apparent we were out-growing our location. By having this facility in the Midlands, we now have much better coverage of the UK and now offer even more support to our customers".

  • Remote diagnostics becomes a reality 

    The X-431 PRO 3 tool joins Launch UK and is a potential game-changer, offering real-time remote diagnostic checks using wireless, Bluetooth connectivity and 'Golo' telematics. This allows workshops to access real-time vehicle data, to perform real-time diagnostic checks remotely and provides the motorist with information and maintenance guidance via their smartphone. For motorists, Golo technology locates independent garages in their area and will record data concerning safety, anti-theft and driving behaviour. Dave Richards, Launch UK managing director, said: "The launch of Golo is another example of how the independent aftermarket can respond to the threat of vehicle telematics from vehicle manufacturers. "It is very exciting for the independent garage... Not only is Golo going to be a valuable tool for retaining customers in the independent aftermarket, but it will also create a social community among garages and drivers, strengthening the reputation of the independent aftermarket." Launch PRO 3 has a built-in social network service that allows workshops to connect to a virtual community and seek instant help with challenging faults. Technicians can access a comprehensive vehicle database and repair tips to improve workshop efficiency. The PRO 3 tool has various other features. These include the ability to recognise the diagnostic features of other tools in the X-431 series, reading and clearing DTCs, interpreting and reading a vehicle's data stream, also performing actuation tests. Workshop technicians can use the PRO 3 to diagnose faults on 90% of all European, Asian and American vehicle brands.

  • The next generation of scopes 

    The PicoScope 4225 and 4425 are the new 2 and 4 channel automotive scopes which replace the long-serving PicoScope 4223 and 4423 and which provide a number of new features and upgraded performance for the same price as the older scopes. New features provide technicians with additional measurement capabilities and techniques. These capabilities allow the capture of more information and finer detail, over extended periods of time. 'ConnectDetect' is a new feature that confirms on-screen and on-device, that your probe has made connection to the circuit, ideal for hidden connectors. Read more about this in our TestBench on page 35. The BNC input channels are isolated from each other and from USB ground, allowing the technician to directly measure across components, carry out voltage drop tests, test reverse polarity motors and measure floating ground sensors using all inputs at the same time. The input range has been increased to ±200V, reducing the need for attenuation when testing injector circuits, for example. The new scopes can capture up to 400 million samples per second and can measure high speed CAN and FlexRay signals. The new generation scopes have eight times the memory of their predecessors. More samples can be taken and finer detail is revealed when zooming, with the additional benefit of more waveform buffers to review when looking for elusive, intermittent faults.
