Voltage: Volt Ampera Bolt OBD

The most comprehensive diagnostic and control app for Chevrolet Volt / Opel Ampera / Vauxhall Ampera / Holden Volt. Chevy Bolt and Opel Ampera-E are currently supported from 2017 to 2023. Connect via a supported ELM327 Bluetooth LE or Wi-Fi OBD2 adapter and take full command of your vehicle. RECOMMENDED ADAPTERS For full compatibility — SW-CAN access, HVAC and Infotainment communication, remote start, and door unlock — use an OBDLink MX+ or vLinker MS. Bluetooth LE and Wi-Fi adapters provide limited compatibility. ENHANCED VEHICLE CONTROL • Remote start (pre-conditioning) and climate control within Bluetooth range for vehicles before 2019 • Battery heater for improved cold-weather range • Charge management and scheduling • Remote door and window operation • Engine control with ON / OFF / Release support • Wake the car remotely to query modules without powering it on • Module reset and DTC clearing HV UNLOCK FUNCTION "Unbrick" your car and stay on the road with the HV Unlock function. Enable charging on Ampera 2012 by resetting the Service High Voltage Charging System. PROFESSIONAL DIAGNOSTICS • Deep DTC scan across all discovered modules, including SW-CAN network access • 100+ live parameters with two-column monitoring mode • Real-time battery pack analysis: cell voltages, temperatures, BECM voltage & current • Weak Cell active test with guided instructions and a clear verdict • Battery Coolant Pump and heater control with feedback values and charts • HW Info with module programming dates and ECM calibrations MONITORING PARAMETERS Nine dedicated screens, every value charted in real time: • Efficiency — State of Charge (displayed & raw), EV range, kWh used, EV efficiency, fuel efficiency (hybrid) • Powertrain — HV power, HV current, HV inverter voltage, transmission fluid temp, MGA & MGB motor temps, aux transmission pump speed, gear shifter position. For hybrids it also reports engine speed, engine oil & coolant temps, EGR commanded (Gen 2), EGR cooler temps (Gen 2), and HPCM engine-startup reason. • HV Battery — Pack voltage, internal resistance, cell delta, average and minimum cell voltage, six individual battery temps, battery coolant temp & speed, battery heater power, battery conditioning mode, outside/inside temps, and the last five charging-session histories. • Charger — Charger state, charging level, AC input voltage/current/power, DC output voltage/current/power, charging-system status, and (2016+) AC & DC duty cycles. • Charger Plus — Extended charger diagnostics, including duty-cycle on 2016+ vehicles. • Climate — HVAC target temp, windshield temp, cabin heat power, AC power, AC speed, blower speed, HVAC coolant temp (2016+), outside & inside temps, and remote-start counters. • 12V — 12V voltage, current, power, state of charge, charging state, maintenance mode. • 12V Power (per-module) — Individual 12V supply voltage reported by every major control module: ECM, HPCM1, MGA, MGB, HPCM2, BECM, EBCM, Brake Booster, EPS, ASCM, HVAC and Radio. Power-electronics coolant temp and pump speed included. • TPMS — Live tire pressure for all four wheels. VEHICLE HISTORY & DATA MANAGEMENT • Full history view with vehicle selection and deletion • Export, import, and edit your vehicle history with the built-in editor HEALTH INSIGHTS Critical vehicle health analysis and maintenance recommendations — ideal for DIY enthusiasts, used car buyers checking battery health, and owners tracking long-term performance. POLISHED EXPERIENCE Modern UI with Dark / Light / System theme support, a bottom status bar for at-a-glance status, and full multi-language support.
