Dr. Prius / Dr. Hybrid

Dr. Prius / Dr. Hybrid is a professional-grade mobile diagnostic application that transforms your smartphone into a powerful tool for assessing the health of your Toyota or Lexus hybrid vehicle's high voltage battery. Dr. Prius / Dr. Hybrid provides mechanics and informed owners with critical data and diagnostic tests, replacing equipment that typically costs thousands of dollars. Users connect a compatible OBD-II adapter to their vehicle, and Dr. Prius / Dr. Hybrid delivers detailed insights into battery performance, life expectancy, and potential issues, enabling informed maintenance decisions and verifying battery health with a shareable certificate.

Real-Time Battery Monitoring and Data Display

Upon connecting a supported ELM327 Bluetooth adapter, users launch Dr. Prius / Dr. Hybrid to access real-time data streams from their hybrid battery. The app displays vital statistics like individual cell voltages, battery state of charge, and temperature through clear, color-coded charts and numerical readouts. Users can observe fluctuations and identify weak or failing battery blocks by spotting significant voltage deviations from the norm. This continuous monitoring is the first step in any diagnostic procedure with Dr. Prius / Dr. Hybrid, providing a live snapshot of the battery's operational status.

Conducting the Battery Life Expectancy Test

This proprietary function is a core feature of Dr. Prius / Dr. Hybrid. Users initiate the test from the main menu, which then guides the system through a specific discharge and recharge cycle. The app’s algorithm analyzes the battery's performance during this process, calculating its remaining useful life as a percentage. Users receive a clear result indicating the battery's health, often presented alongside a color indicator (e.g., green for good, red for poor). This test is crucial for determining if a battery replacement is necessary or for certifying a used vehicle's battery condition.

Performing a Comprehensive Full Battery Test

For a deeper diagnostic, the Full Battery Test in Dr. Prius / Dr. Hybrid goes further than the life expectancy check. Users start the test, and the app performs an automated series of checks on the battery pack's overall system health. It evaluates balance, internal resistance, and the effectiveness of the battery management system. Upon completion, Dr. Prius / Dr. Hybrid generates a detailed report that summarizes the findings, often including a pass/fail grade. This report can be printed or shared directly from the app as a certified document for customers or personal records.

Reading and Resetting Diagnostic Trouble Codes

Like a standard OBD-II scanner, Dr. Prius / Dr. Hybrid allows users to interface with the vehicle's computer to read and clear error codes. Users navigate to the "Codes" section to scan all ECUs, including those specific to the hybrid system. The app retrieves and displays any stored codes with their descriptions. For mechanics, a key function is the ability to reset these codes after performing repairs. This feature helps verify that an issue has been resolved and is an integral part of the troubleshooting workflow facilitated by Dr. Prius / Dr. Hybrid.

Accessing Customization and Maintenance Functions

Beyond diagnostics, Dr. Prius / Dr. Hybrid provides access to various vehicle customization settings. Users can navigate to specific menus to disable audible alerts like the reverse beep or the seatbelt warning chime. It also allows for adjustments to the hybrid battery cooling fan speed, which can be useful for optimizing performance in certain climates. These features provide an added layer of control, letting owners and technicians tailor specific vehicle behaviors directly through the Dr. Prius / Dr. Hybrid interface without specialized dealership tools.

Utilizing the Integrated Repair Shop Locator

Dr. Prius / Dr. Hybrid includes a practical tool for finding professional assistance. Users can access a built-in directory to find nearby hybrid repair shops that are reputable and familiar with these vehicle systems. This feature leverages location data to provide a list of nearby options, making it easier for owners to find qualified help after using Dr. Prius / Dr. Hybrid to identify a potential problem. It bridges the gap between DIY diagnostics and professional repair, adding significant value for the end-user.
