Sometimes a vehicle will suffer from driveability issues and fault codes relating to valve timing. Such conditions can be difficult to diagnose without the correct equipment.
The purpose of variable valve timing (VVT) is to help increase the engine’s volumetric efficiency and limit the exhaust gasses produced by the vehicle. By altering when the valves open and close you can optimize the performance of the engine.
The development of Advanced Driver Assistance Systems (ADAS) have been a technological leap forward for the automotive industry. However, new challenges handling car repairs for workshops and body shops when ADAS systems are impacted are common.
This deep-dive case study walks through the steps taken when a 2016 Mercedes E350 was involved in a collision and repaired, only to find that a warning message indicating ‘lane keeping assist inoperative’ was displayed in the instrument cluster.
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.
The rise in demand for ‘high-tech’ vehicles has challenged engineers to rethink and create more sophisticated internal systems which promote efficiency. The humble motor is a great example of this with many vehicle manufacturers now using brushless direct current (DC) motors in automotive applications. The brushless motor has many advantages when compared to conventional ‘brushed motors’ but whilst more efficient, the commutation control of the brushless motor is more complex.
