SupportGeneral 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...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...GM OBD Driving Cycle
A complete driving cycle will perform diagnostics on all monitored systems and can usually be completed in less than fifteen minutes. Performing a GM OBD-II Driving cycle: Cold Start In order to be classified as a cold start the engine coolant temperature must be below 122F (50C) and within 11F (6C) 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 half minutes w...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 or smartphone for easier monitoring of a vehicle in a garage or on the road. For example, the OBDKey WLAN and the PLX WiFi allow a nearby iPod Touch or iPhone to stream OBD data for use in an app such as Rev or DashCommand. GPS device manufacturers...
