YES >> GO TO 5. NO >> Repair or replace harness or connector. 5. READ VALUE OF CONSULT-III (ACCUMULATOR PRESSURE SENSOR) 1. Reconnect the brake ECU connector and the brake actuator connector. 2. Connect the CONSULT-III. 3. Turn the ignition switch ON. 4. Select the “DATA MONITOR” on the CONSULT-III. ABS/VDC: 5. Depress the brake pedal 4 or 5 times to operate the pump motor, and check the output value on the CON- SULT-III with the motor stopped (not braking). NOTE: Accumulator pressure sensor voltage does not drop. Is the inspection result normal? YES >> GO TO 6. NO >> Replace brake actuator assembly. 6. RECONFIRM DTC 1. Turn the ignition switch OFF. 2. Clear the DTC. 3. Turn the ignition switch ON. 4. Check if the same DTC is recorded. Result A >> Check for intermittent problems (symptom simulation). B >> Replace brake ECU. 7.
