Question

Quizplus · Accepted Answer

Both technicians are correct. Bleeding the conventional brake system before the ABS modulator is a common procedure to ensure that air is removed from the entire system efficiently. A scan tool may indeed be required to bleed the ABS modulator in many vehicles, as it can activate the ABS pump and open the solenoid valves, allowing for a complete bleed of the system.
