Common Fault Codes for Smart
In Israel, Smart Fortwo and Forfour models are the most common, known for their compact size and urban convenience. Common issues can include electrical system problems, the 12V battery (even in electric models), and faults related to the electric drivetrain or robotic gearbox in older models.

Tips for Smart Owners
- If a 'check engine' light appears, first verify the condition of the 12V battery, as a weak battery can trigger various fault codes, including those related to the electric drivetrain.
- For Smart electric (EQ) models, fault codes related to the Battery Management System (BMS) or HVAC system require professional diagnosis as they may indicate issues with the high-voltage battery or on-board charger.
