OBD Software Development Getting started
Engineers and programmers are often intimidated by the prospect of interfacing with OBD-II systems. Five protocols, a dozen modes, hundreds of parameters, thousands of trouble codes. Who can figure it all out? The good news is, tapping into
OBD Future applications
Like most data-driven technologies (such as GPS and cellular data), the future of OBD-II technology lies in convergence. For example, newer OBD-II scanners and readers are starting to integrate Wi-Fi technology to wirelessly connect to a nearby laptop
What is the best time and mileage for vehicle mai
Car maintenance is divided into major maintenance and minor maintenance. At ordinary times, the maintenance we do every 5000 km or half a year mainly refers to minor maintenance, including changing engine oil and filter, checking whether vehicle headlights, tires and brake pads are normal; while major maintenance mainly refers to changing engine coolant, timing belt, spark plug, changing transmission lubricating oil, changing brake oil and brake pads, as well as changing vehicle tires. minor mai
General Motors Driving Cycle
A complete driving cycle should perform diagnostics on all systems. A complete driving cycle can be done in under fifteen minutes. To perform an OBDII Driving cycle do the following: Cold Start. In order to be classified as a cold start the engine coolant temperature must be below 50C (122F) and within 6C (11F) of the ambient air temperature at startup. Do not leave the key on prior to the cold start or the heated oxygen sensor diagnostic may not run. Idle. The engine must be run for two and a h
