Overview
The TOPDON TC004 Mini is a pocket thermal imager with 240×240 TISR resolution and 15-hour battery life — for spotting overheating components, HVAC issues, and electrical hotspots in the garage.
Thermal imaging shows problems codes cannot — clogged radiators, dragging brakes, misfiring cylinders, and parasitic drain heat signatures.
Key Features
- 240×240 TISR thermal resolution
- 128×128 IR sensor
- 15-hour battery life
- Handheld standalone operation
Automotive Use Cases
TC004 Mini thermal imaging helps you find faults that OBD2 codes miss:
- Overheating wiring, connectors, and alternators
- Cooling system blockages and thermostat failures
- Brake drag and wheel bearing heat signatures
- HVAC temperature splits and blend door issues
- Cylinder misfires visible as exhaust manifold temperature differences
How to Use This Tool
Power on the TC004 Mini, point at the area under investigation, and compare temperature patterns against known-good references. Scan radiators, exhaust manifolds, brake rotors, and wiring while the system is under load. Save images when the TOPDON app or built-in storage supports documentation for before/after comparisons.
Compatibility
Standalone thermal camera — works on any vehicle system where temperature differences reveal faults.
Who Should Buy This
DIYers and techs adding thermal diagnosis alongside OBD2 scanning.
Why Choose TOPDON
TC004 Mini makes thermal imaging affordable — complement your scanner with heat-pattern diagnosis.
Power & Updates
Standalone (internal battery). Firmware updates via TOPDON software where applicable.
