Answer

Usually, a device reads gear position data through J1708 or J1939 protocols. Some vehicles provide these data differently and the device is unable to decode the information. In that case, we use accelerometer data to determine if the vehicle is moving forward or backward.

Generally speaking, even if the device is able to read gear positions from the ECU, every vehicle provides the gear position differently and our devices are not always able to read the exact gear positions. So, it rather indicates them as reverse, neutral or drive.
