Sensor construction and measuring waveforms is a useful place to start when getting to grips with complex brake system faults. Take a look at the article to learn more.
FlexRay is similar to CAN Bus as the data is transmitted over two twisted wires, which act to reduce the effects of external interference on the differential voltage between both wires. Data transfer speeds can be up to 10 times faster than CAN bus, operating at speeds up to 1 Mbits per second.
Controller Area Network (CAN) is a data transfer network designed to allow many nodes (modules) to communicate using a standard structure and format. This article will provide the technician with the necessary tools to successfully validate a CAN bus signal and help to identify faults where present.
Local Interconnection (LIN) Bus is a low speed cost effective alternative to CAN bus. LIN gets its name from being a ‘local’ sub-system. Data Transfer speeds can be up to 20 kBits/second. It is designed for sensor/actuator level.
There are many different ways to diagnose ignition problems on a vehicle using a Snap-on lab scope.
A very handy feature of the diagnostic software on your Snap-on scan tool is the parameter identification (PID) trigger function. You can set minimum and maximum values and if your data goes outside of those the PID trigger function will automatically save it for you so you can see it later.
Find out how the combination of a Snap-on diagnostic tool and software can help make key programming easier.
Learn about some short but important steps you need to follow when it comes to ensuring that replaced modules are fully recognised by a vehicle.
Make your life easier by using a Snap-on lab scope and scan tool to check and verify the correctness of vehicle scan data - on the same screen at the same time.
