3,000+ CAN signals for Tesla. Live decode, ECU, Errors. Bluetooth OBD adapter
CAN-View for Tesla reads Tesla CAN bus data for advanced vehicle diagnostics over a Bluetooth OBD-II adapter. One app covers Model S/X and Model 3/Y lines — choose the platform that matches your car and work in an interface built for that generation. SIGNAL COVERAGE • Model S/X line: 3,000+ decoded CAN signals (3,036 in the bundled MSX value-description dictionary; the live signal catalog is downloaded for your account and may include additional IDs). • Model 3/Y lines: 2,350+ decoded CAN signals per M3Y profile (2,350 in the bundled M3Y dictionary). • Raw frames are decoded with platform-specific signal dictionaries, scaling, and enum labels where defined — so you see names and values, not only hex bytes. GETTING STARTED • Sign in with a MASCorp Diagnostics service account. • On “Select vehicle platform”, pick Model S/X, Model 3/Y, Model S/X 2021+, or Model 3/Y 2021+ (2021+ Model 3/Y includes on-screen LFP battery context where that workflow applies). • Pair a Bluetooth OBD-II adapter (ELM327 / STN-class; the app recommends OBDLink MX+ for reliable operation — other adapters may work but are not verified). ECU BLOCKS & SUB-BLOCKS • Live parameters are organized by vehicle ECU blocks (for example BMS, DI, Thermal, Gateway, ChargePort, Display, FrontController, and more — the list depends on your platform and profile). • Open a block to see its live parameter list (sub-block / tab view): decoded signals stream for that ECU group. • A dedicated “Errors and CAN diagnostics” entry lets you open fault-oriented views for the selected block alongside ordinary parameters. DIAGNOSTIC ERRORS & ALARMS • Block-level diagnostic screens show active alarm-style signals for the ECU you are viewing. • Values update in real time while the OBD session is running, with human-readable signal names from the dictionary. • Use this view together with the parameter list to correlate faults with live CAN data on the same block. BATTERY BRICK VOLTAGE (BMS) • Where your profile supports it, a brick voltage grid shows per-cell voltages from the pack. • Cells are color-coded (high / mid / low vs. pack maximum) so outliers stand out quickly. • Tap a brick to open a voltage chart for that cell over time. • Layout adapts to the platform (including module-grouped grids on Model S/X where applicable). CUSTOM PARAMETERS • Build your own live parameter set: pick signals from the catalog, order them, and stream only what you need. • Save layouts on the device for repeat workshops or road tests. • Start and stop live decoding independently of the main ECU block screens. WIDGET DASHBOARD • Arrange favorite signals on a personal dashboard with live numeric readouts and charts. • Pin, resize, and organize widgets for at-a-glance monitoring while you work. • Ideal for keeping a small set of critical values visible without scrolling long block lists. ALSO INCLUDED • Light and dark theme across the unified shell and diagnostic modules. • Software license and privacy policy links in Settings. • No Google Play in-app billing in this package. REQUIREMENTS • Active MASCorp Diagnostics account and internet access to download profiles and dictionaries. • Bluetooth OBD adapter paired with your phone; the vehicle does not need its own Internet connection for live CAN viewing.
