EV-BOY Pulse: Leaf OBD Checker

See a plain-English battery verdict, check your 12V system and understand fault codes — built first for Nissan LEAF and BMW i3.

EV-BOY Pulse helps EV drivers turn supported on-board diagnostic data into clear, practical guidance.

Built and validated first for Nissan LEAF and BMW i3, it helps you understand battery condition, 12V behaviour and stored fault codes without having to interpret a wall of raw numbers.

BATTERY VERDICT, WITH CONTEXT

See a plain-English battery verdict alongside supported battery-health readings, state of charge, usable-capacity estimates and cell-balance context.

Reading confidence helps you judge whether a result is ready to rely on or whether a better test condition may improve it.

12V SYSTEM CHECK

Use guided readings to check the auxiliary 12V system. EV-BOY Pulse shows collection progress, a stable reading and clear next-step guidance when a result may deserve further attention.

FAULT CODES EXPLAINED

Scan supported stored diagnostic trouble codes and view a plain-English explanation, severity indication and sensible next step. Focus on what to investigate rather than a wall of technical codes.

MADE FOR NISSAN LEAF AND BMW i3 FIRST

Nissan LEAF and BMW i3 are the first fully validated vehicle profiles. Further EV profiles will be added only as they are validated.

WHAT YOU NEED

EV-BOY Pulse requires a compatible Bluetooth Low Energy (BLE) OBD adapter and a supported vehicle for live diagnostic readings. Adapter compatibility and available data can vary by vehicle, model year and connection quality.

IMPORTANT

EV-BOY Pulse provides model-based diagnostic guidance from on-board data. It is not a manufacturer inspection, safety certification, warranty decision or repair guarantee. For safety-critical, persistent or urgent vehicle faults, obtain professional diagnosis.
