Universal Car Motor Tester
Emergency EPB Release & 12V Motor Testing Tool
Forcibly release or reset electronic parking brakes (EPB) during power loss, system failures, or brake maintenance. Features dual-channel control with built-in safety protection.
Versatile Application Scenarios
EPB System Troubleshooting
Forcibly releases the brake caliper motor when stuck due to sensor faults or control module errors to facilitate diagnosis.
Emergency Road Rescue
Safely unlocks the parking brake to move disabled vehicles without forcing mechanical components or causing tow-hook damage.
Workshop Vehicle Movement
Quickly releases locked electronic handbrakes when the vehicle has no battery power, facilitating easy workshop repositioning.
Vehicle Maintenance
Manually releases the EPB caliper setup when replacing brake pads or brake discs, preventing motor burnout during service.
Key Performance Features
Smart Dual-Channel Control
Easily shift between braking and release modes using the bidirectional rocker switch marked with clear ◀ O ▶ symbols. Provides direct mechanical action to run caliper motors forward or backward safely.
Automotive Motor Testing Tool
Beyond electronic handbrakes, this diagnostic tool can connect and test other 12V DC auxiliary components on the vehicle including power window motors, windshield wipers, and blower fans.
Product Quality In-Depth Comparison
1. Heavy-Duty Fuse Holder
Loose structure that easily detaches and breaks during road use.
Tight structure, dust and moisture proof, built for service shops.

Frequently Asked Questions
Q: How do I operate the rocker switch safely to avoid blowing the fuse?
A: Connect the clamps to the 12V battery and connect the pins to the caliper motor. Engage the rocker switch toward release or brake. You must stop pushing the rocker switch immediately once the handbrake is fully released or fully applied to avoid motor overload and fuse blowout.
Q: What vehicles are compatible with the universal adapter leads?
A: This tool features universal terminal pin leads that connect directly to motor terminals. It fits Toyota, Lexus, Nissan, European, and most modern domestic cars equipped with electronic parking brakes (EPB).
Q: How do the built-in safety protection features work?
A: The tool features reverse polarity protection to safeguard vehicle electronic systems if you hook up the battery clamps incorrectly. Additionally, a built-in 40A fast-blow spade fuse protects the circuit from sudden high current spikes.
