All Diagnostic Issues
Battery & BMS (Energy Storage System)
The iQube uses NMC (Nickel-Manganese-Cobalt) Li-ion chemistry with capacity options of 2.2 kWh, 3.4 kWh, and 5.1 kWh. The BMS monitors SoC, SoH, and cell temperatures via CAN bus communication.
Hub Motor & MCU (Motor Control Unit)
The iQube uses a 3-phase BLDC hub-mounted motor generating 140 Nm peak torque. Hall Effect sensors embedded in the stator provide rotor position feedback to the MCU for commutation.
Software, VCU & SmartXonnect
The Vehicle Control Unit (VCU) coordinates the MCU, BMS, and telematics. SmartXonnect provides Bluetooth, GPS, and GSM connectivity requiring proper handshake protocols.
Chassis, Frame & Structural Components
The tubular frame construction supports 3 battery packs. A recall affecting ~40,000 units (July-Sept 2023) addressed bridge tube defects impacting handling.
Brakes & Regenerative Braking System
Front 220mm disc / Rear 130mm drum configuration with CBS. Regenerative braking is triggered by the rear brake switch - improper cable adjustment affects both regen and power delivery.
MCU Blink Codes (Technician Diagnostic)
These codes are read via OBD diagnostic tool or LED patterns on the controller during diagnostic mode. They provide granular insight into the MCU and electrical subsystems.
Dashboard B2Error Codes (User Facing)
These codes appear on the TFT dashboard to alert the user. Some require immediate attention while others may clear after a system reboot.
Charger LED Status & Fault Diagnosis
The portable charger (650W/950W) communicates status via LED. The charger handshakes with the BMS before initiating charge. Issues may stem from grid quality, port condition, or internal faults.
Periodic Maintenance Schedule
While EVs eliminate oil changes and valve clearances, critical safety checks for torque, brakes, and structural integrity remain essential. The rear axle nut torque check is the most critical safety operation.
