WHEN PERFORMING CERTAIN TYPES OF NON-ABS BRAKE-RELATED VEHICLE DIAGNOSTICS, IT MAY BE NECESSARY TO SPIN THE WHEELS. SPINNING THE WHEELS ON VEHICLES EQUIPPED WITH ANTILOCK BRAKES (ABS) MAY SET FALSE ABS FAULT CODES. BEFORE RELEASING THE VEHICLE TO THE CUSTOMER, CHECK TO SEE IF ANY ABS FAULT CODES HAVE BEEN SET.


IF THERE ARE ANY, VERIFY THEIR AUTHENTICITY AND CLEAR ANY FALSE ABS FAULT CODES.

TO CLEAR ABS FAULT CODES, ACCESS THE ABS PROCEDURE THROUGH THE UTILITIES SECTION OF THE T-100 TERMINAL. THE TECH 1 MAY ALSO BE USED TO CLEAR ABS FAULT CODES.
