Dr. Prius is an app designed for professional Toyota/Lexus hybrid repair shops and owners to comprehensively evaluate the health of their High Voltage (HV) battery. Transforming your mobile device into a professional-grade diagnostic tool (typically costing thousands of dollars), it's trusted by 439+ professional repair shops worldwide.

Dr. Prius performs tests and provides access to crucial battery data, enabling swift identification of potential problems with a simple tap on your smartphone's screen. Avoid costly battery failures—test your battery and generate a certificate to verify its health.

This app requires an ELM327 Bluetooth OBD interface to communicate with your hybrid vehicle. Note that many inexpensive ELM327 clones may not function correctly due to limitations in switching between vehicle ECUs. For detailed information or adapter compatibility questions, visit http://PriusApp.com/obd.html or email us. Using a WiFi OBD2 adapter is generally discouraged due to potential internet connectivity interruptions during testing.
