Without Scan Tool

CLEARING ABS DIAGNOSTIC TROUBLE CODES
ABS diagnostic trouble codes can only be cleared with a Tech 1 or equivalent scan tool. The Electronic Brake Control Module/Electronic Brake and Traction Control Module (EBCM/EBTCM) will not allow diagnostic trouble codes to be cleared until all diagnostic trouble codes have been displayed. Diagnostic trouble codes cannot be cleared by unplugging the EBCM/EBTCM, disconnecting the battery cables, or turning off the ignition.
