It reads and stores the TPSM information for what reason I don't know as this information is useless to erase your flashing or solid dash light. It shows the battery level on the pressure gauge and the tire pressure without using a pressure gauge. I bought this device to be able to change the winter tires on my car, but this device does not work to clear codes. It is not possible to add an OBD unit to this device! A complete waste of money and I just passed the return window but 2 weeks away! Waste of $130 for a recorder I could have bought for less than $50. Not thrilled with advertised skills so be careful!
