alOBD Scanner™ is a series of OBD2 Scantool applications for Android™. It works with ELM™ Bluetooth Device that connects to vehicle's OBD II Port, allowing OBD 2 PID data collection and storage, reading and clearing active DTCs, resetting Check Engine light. The program supports viewing pending DTCs as well. Data from engine parameters can be saved to device's internal storage as a CSV file. Viewing of the saved data in a graphical form is available. Data can also be exported using Android's standard export services: e-mail, Bluetooth, etc.
Connecting to vehicle’s OBDII port, alOBD Smog PreCheck app will run a preliminary check of vehicle’s emissions system in order to assess its readiness for a state Smog Check. It will check OBD DTC, on-board monitor status, assess oxygen sensor performance and, for some vehicles, check select OBD2 Mode $06 parameter values to be in range. Upon completion, it will display a result as PASS, FAIL or INCONCLUSIVE accompanied by a confidence percent value. This app is designed to provide an assessment of a vehicle emission’s system prior to a mandated government emissions check. Also, when considering a car purchase, this app can be used as a preliminary pre-purchase inspection. For more information read the User's manual
alOBD Terminal is a free application for Android that allows the user to interact with vehicle's computer network (PCM/ECU/TCU) directly by typing low level commands and receiving vehicle's reply. Both the generic OBDII standard commands are accepted as well as specific modes (modes above $10) may be supported. By using specific physical addresses a particular computers (for instance, instrument cluster, ABS module or transmission control computer can be controlled. This application is for advanced user only. In order to be effective, one must understand OBD protocols as well as know specific commands for specific vehicle. Some of this information can be attained from Google searches.
This alOBD ScanGenPro™ is designed to provide basic automotive diagnostic and vehicle data collection. The intended audience of this product is car geeks that are familiar with the operation of an engine control computer, vehicle sensors and generic OBD parameter set. This application may also be suitable for a professional shop for a quick diagnosis of the vehicle's emissions system. Each vehicle's control computer constantly collects data from all sensors and adjusts actuators in order to keep the powertrain operating at nominal values. In addition, the on-board computer runs diagnostic tests to ensure the vehicle is operating in accordance with emission standards. Some PIDs (like Engine Coolant Temperature or Vehicle Speed) return sensor and/or vehicle data and, when started, will continue to display up-to-date data on the digital readout and on the graph. Others only provide status of the current capabilities or installed equipment. When those are requested, the collection will automatically stop after one iteration.
