Features unique patented all-in-one backlit screen display and 3 color LED display for quick State Emissions readiness check.Automatic refresh updates data every 30 seconds when connected to the vehicle – an easy way to verify repair completion.Links to all OBD2 protocols including C.A.N.All-in-one backlit display that shows over 20 pcs of vital diagnostic information at any one time.Displays, records and plays back OBD2 live data graphing on the tool.Designed to retrieve Enhanced and Transmission diagnostic codes in all OBD2 (1996 and newer) and some of the most popular OBD1 (1981 to 1995) vehicles.Since the frequency of this AC voltage changes in direct proportion to the speed of the rotor, the frequency is used by the skid control ECU to detect the speed of each wheel. When the rotors rotate, the magnetic field generated by the permanent magnet in the speed sensor induces AC voltage. Each of the front and rear rotors has 48 serrations. These signals are used for control of the ABS system. The speed sensor detects wheel speed and transmits the appropriate signals to the skid control ECU.

In some cases, the intelligent tester cannot be used when the ABS warning light remains on. (c) Repeat the above operation 3 times or more and check that the ABS warning light goes off. (b)Drive the vehicle at the vehicle speed of 31 mph (50 km/h) and keep depressing the brake pedal strongly for approximately 3 seconds. (a)Keep the vehicle in the stationary condition for 5 seconds or more and depress the brake pedal lightly 2 or 3 times. (a) Drive the vehicle at 12 mph (20 km/h) for 30 seconds or more and check that the ABS warning light goes off.
