{"assets":{"app_about":{"about_data":{"description":"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.

RECOMMENDED ADAPTERS
For full functionality — SW-CAN access, HVAC and Infotainment communication, remote start, and door unlock — use a vLinker MC / MC+ or OBDLink MX+. Standard ELM327 adapters work for most diagnostics and monitoring features.

COMPLETE 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 — including from Android Auto
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 INCLUDE:

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. Hybrid mode 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 reason/remote-starts-left 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, plus radio and HVAC on SWCAN-equipped vehicles. Power-electronics coolant temp and pump speed included.

🛞 TPMS — Live tire pressure for all four wheels (front-left, front-right, rear-left, rear-right).

VEHICLE HISTORY & DATA MANAGEMENT
Full history view with vehicle selection and deletion
Export, import, and edit your vehicle history with the built-in editor
Compare multiple vehicles side-by-side using key performance parameters

HEALTH & MAINTENANCE 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.
