[Bi-Directional Control for Fast Troubleshooting]
The Bluetooth Diesel Diagnostic Tool X431 PRO5 features Bi-directional Control, also known as Active Test, Actuator Test, and Inspection Tests. It can send the commands to ECUs, read the ECU data to determine the completeness of the system or parts and monitor the operation of the actuators, letting you quickly know if a specific system, component, or subsystem is functioning properly or not.
With this bi-directional scan tool, you don't need to struggle to disassemble individual on-board parts & ECUs to find a small problem. It also can be universally applied to all vehicle systems like ABS, SRS, Engine, TPMS, BCM, Headlamps, Windscreen Wipers, Windows, Doors, Sunroof, Mirrors, for pinpointing problems within 5 minutes.
Here we have some examples for the Active test:
✔️Switch the SRS light on and off;
✔️Cycle the a/c clutch on and off;
✔️Switch the cylinder on and off;
✔️Conduct the injector buzz test;
✔️Turn on/off the radiator fan;
✔️Operate the acceleration device test;
Note: Not universal for all vehicles. Available tests vary depending on the make, year, and model.
