C1246, C1281, C1364 BRC-89 < COMPONENT DIAGNOSIS > [VDC/TCS/ABS] C D E G H I J K L M A B BRC N O P Is the inspection result normal? YES >> GO TO 2. NO >> Repair or replace harness or connector. 2. READ VALUE OF CONSULT-III (MASTER CYLINDER PRESSURE SENSOR) 1. Reconnect the brake actuator connector. 2. Connect the pedal effort gauge. 3. Connect the CONSULT-III. 4. Turn the ignition switch ON. 5. Select the “DATA MONITOR” on the CONSULT-III. ABS/VDC 6. Check the output value of the master cylinder pressure snesor at braking. NOTE: Output voltage must be proportional to the degree of pedal depression. There should not be a big differ- ence between outputs of sensor 1 and sensor 2. Is the inspection result normal? YES >> GO TO 3. NO >> Replace brake actuator assembly. 3. READ VALUE OF CONSULT-III (WHEEL CYLINDER PRESSURE SENSOR) 1. Turn the ignition switch OFF. 2. Turn the ignition switch ON. 3. Select the “DATA MONITOR” on the CONSULT-III.
