OBD Now, in conjunction with an ELM327 chipped scan tool (Bluetooth or Wi-Fi), transforms your Android phone or tablet into a complete OBDII diagnostic tool. OBD Now is designed to report on all the OBDII Services of the OBDII specification in a minimal amount of time. An experienced operator can quickly connect to each vehicle as presented. OBD Now's simple menu driven structure guides the operator through all the OBDII services. Within a minute or two of connecting with OBD Now, an operator can quickly determine if a vehicle is running normally or has faults and requires further investigation. It is especially useful to the workshop manager who is required to access 30-40 at the start of a working day. This allows the workshop manager to plan his daily workload and assign more highly skilled technicians to the vehicles presenting with the most serious problems. Of course the car enthusiast/home mechanic also gets to enjoy same features.
