Independent Diagnostics Using Tesla Toolbox – Mobile Service

Independent Diagnostics Using Tesla Toolbox

Independent diagnostics for Tesla vehicles at your home or workplace.

MaintainEV is an independent service provider and is not affiliated with, endorsed by, or authorized by Tesla, Inc. Available diagnostic data and functions depend on the vehicle, its software, and applicable access permissions and owner authorization. MaintainEV does not claim diagnostic access or capabilities equivalent to Tesla Service Centers, or access to Tesla's internal historical service records.

MaintainEV uses Tesla Toolbox to access advanced diagnostic and service functions beyond the information normally available through the Tesla app or vehicle touchscreen. This helps identify the cause of alerts, charging problems, thermal-system issues, suspension concerns, communication faults and other difficult-to-diagnose Tesla problems.

Independent mobile diagnostics using Tesla Toolbox are available in the Edmonton area, with service available elsewhere in Alberta and Western Canada by arrangement.

What can Tesla Toolbox diagnose?

• High-voltage battery and drive-unit faults
• Advanced vehicle alerts and fault-code analysis
• Thermal-system operation, including pumps, valves, heaters and A/C components
• Charging and onboard-charger concerns
• High Voltage Interlock Loop (HVIL) faults
• ECU communication and module faults
• Air-suspension diagnostics and calibration on applicable Model S and Model X vehicles
• TPMS and applicable wheel-sensor functions
• Vehicle alert history and diagnostic information

Why use Tesla Toolbox diagnostics?

A warning on the touchscreen often tells you that a problem exists without identifying the underlying cause. Toolbox provides deeper vehicle information and diagnostic routines that can help narrow down the affected system before parts are replaced unnecessarily.

Can MaintainEV diagnose my Tesla without taking it to a service centre?

Yes. MaintainEV provides independent mobile diagnostics for Tesla vehicles and can perform many diagnostic procedures at your home or workplace.

Which Tesla models can you diagnose?

MaintainEV works with Tesla Model S, Model 3, Model X and Model Y, with available diagnostic functions depending on vehicle generation and configuration.

Can Toolbox help with intermittent or historical faults?

Depending on the vehicle and fault, diagnostic information and alert history can provide useful context for intermittent problems that may not be active when the vehicle is checked.
