Tech A says that an ABS key-on system test checks for faults in the vehicle's base brake system. Tech B says that on most vehicles ABS DTCs are stored in memory for later retrieval. Who is correct? Select one: a. Tech A b. Tech B c. Both A and B d. Neither A nor B

The correct answer is c. Both A and B.<br /><br />Tech A is correct in stating that an ABS key-on system test checks for faults in the vehicle's base brake system. The ABS (Anti-lock Braking System) key-on system test is designed to check the integrity of the ABS components and ensure that the base brake system is functioning properly.<br /><br />Tech B is also correct in stating that on most vehicles, ABS Diagnostic Trouble Codes (DTCs) are stored in memory for later retrieval. DTCs are codes that are generated by the ABS control module when it detects a fault or problem within the system. These codes can be retrieved using a diagnostic tool and can help technicians diagnose and repair issues with the ABS system.<br /><br />Therefore, both Tech A and Tech B are correct in their statements.
