W/ECB
BRAKE MASTER CYLINDER (w/ECB)
ON-VEHICLE INSPECTION
NOTICE: A DTC may be stored during the inspection procedure. Be sure to clear the DTC and check that a normal system code is output after the
inspection is finished.
1. INSPECT BRAKE MASTER CYLINDER SUB-ASSEMBLY
a. Check battery voltage
Standard Value: 10 to 14 V (while the engine is switched off)
b. Connect intelligent tester and pedal effort gauge.
(1) Connect the pedal effort gauge.
(2) Move the shift lever to the P position. Apply the parking brake and connect the intelligent tester to the DLC3.
(3) Turn the engine switch on (IG).
(4) Clear the DTC.
c. Check operation w/o brake booster.
(1) Check and adjust brake pedal height.
(2) Check and adjust brake pedal stroke sensor.
(3) Check pedal free play.
(4) Check pedal reserve distance.
(5) Turn on the intelligent tester and select ECB INVALID to prohibit the brake control (ECB).
(6) Monitor WAS CYL PRS 1, WAS CYL PRS 2, PEDAL STROKE and PEDAL STROKE 2 using the intelligent tester.
(7) Check the value output from WAS CYL PRS 1, WAS CYL PRS 2, PEDAL STROKE and PEDAL STROKE 2 by depressing the brake
pedal.
Standard Voltage
(8) Finish the brake control prohibition on the intelligent tester.
2. INSPECT STROKE SIMULATOR
a. Check battery voltage
