ABS scan toolThis abs scanner diagnoses the brake control module, ABS pump motor, brake switch, wheel speed sensors, Anti lock control solenoids, all vehicle speed sensors and more. The onboard code library is updateable online from a USB connection to your Internet connected PC. A battery backup can also be used to save data and power the brake scanning unit when it is not connected to the obd2 self powered port.
Abs light information
When you're ABS light comes on, the easiest way to find out why is with a brake system scan tool. When the ABS system malfunctions and illuminates the warning light, diagnosis is harder than it should be. This antilock braking system is not as complicated as the vehicle manufacturers are making it.
The government has simplified check engine light diagnosis by mandating the OBD two systems, which standardized and simplified the diagnosis of check engine lights. Unfortunately, this has not trickled down to the antilock braking system. A separate data stream is used and a specialized abs scan tool is needed for the proper diagnosis of the system on most vehicles. When the system turns on the warning light it will set a code just as in standard OBD 2 applications. These codes relate to a specific failure, in part of the computerized antilock braking system. On modern four-wheel antilock brake systems the ABS computer monitors wheel speed through four independent wheel speed sensors and compares that to the vehicles Main speed sensor, which is usually located in the transmission output shaft area, but can also be located on the rear differential. When the computer sees a difference between the actual speed of the vehicle and an independent wheel. It begins to pulse the brake system through a computer-controlled brake modulator. Common causes of ABS lightsIf you have an ABS scan tool you can retrieve the code from the braking system computer that will point you directly to the malfunction area.My experience with diagnosing this system is that the individual wheel speed sensors are fragile and are easy to damage. When I am diagnosing an ABS system, and I have retrieved a code for a wheel speed sensor failure, many times when examining the wheel speed sensor I find damage caused by road debris, ice and snow or other external forces that have damaged that particular wheel speed sensor or wiring connecting the sensor to the ABS module. The abs code that is set is for communication lost from the wheel speed sensor in question.
ABS system diagnosis without the tool is very complicated and time-consuming. We all hope that the Government will standardize the ABS diagnostic system just like they did with the check engine light diagnostics. When you attempt your own DIY ABS diagnostics you can examine each wheel sensor and wiring for signs of an external damage. If you find a sensor or wiring broken you can replace this and then drive the vehicle to see if the light goes out. The antilock brake system is a constant monitor system. Meaning if a code has been set by a failure of one-wheel speed sensor, when this sensor is replaced, the computer will automatically identify that the wheel speed sensor is now producing a signal and will extinguish the ABS light. ABS scan toolsI have searched the Internet for cost-effective ABS scan tools. Below you will find a new tool that has just come out and is priced far below the next closest competitor.The tool that I have listed from OTC is still a good value, because it also does OBD two diagnostics, along with ABS system diagnosis and also includes software to repair SRS light malfunctions. SRS diagnostics is for your airbag system. So this one diagnostic tool can handle the repair of three separate warning lights that may illuminate on your vehicle's dashboard. As a side note, any time that you're ABS light, airbag light or check engine light is on The problem is worth looking into. Too many times I see people driving around with these lights illuminated on their dashes for extended periods of time. These are vehicle safety systems that where put in place to protect drivers. Do not ignore these warnings or safety could be compromised. Help our website grow with a

The repair or replacement of an individual wheel speed sensor in most cases is very simple. The diagnosis of this system is also very simple if you have an ABS scan tool. Unfortunately, this specialized tool is very expensive.
