A bidirectional scanner is a more comprehensive option for car diagnostics. It offers all the functionality of a regular scan tool and takes it one step further by allowing you to send commands to your vehicle’s onboard computer. This can help you pinpoint problems more efficiently and save time on troubleshooting.

Aside from the usual functions of a basic scan tool such as reading and clearing error codes, monitoring sensors, and turning off the check engine light, bidirectional scanners can command various controls on your car. These include actuator tests, system tests, inspection tests, and re-initialization of the control module. They can also read live data and monitor the sensor systems to provide you with a real-time graph. Some bidirectional scanners can even perform a cylinder power balance test.

In addition to providing a complete diagnostic report, some advanced bidirectional scanners are capable of actuating relays, injectors, and coils. They can also re-program the PCM and perform other tasks such as turning on the headlights and air conditioning. They can also identify modules that are likely to fail soon, enabling you to take preventative measures.
