On-Vehicle Inspection

BRAKE: BRAKE MASTER CYLINDER (for 1UR-FSE): 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 the Techstream 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 Techstream to the DLC3.

(3) Turn the engine switch on (IG).

(4) Clear the DTC. Electronically Controlled Brake System

(c) Check operation w/o brake booster.

(1) Check and adjust brake pedal height. Adjustments

(2) Check and adjust brake pedal stroke sensor. Adjustments

(3) Check pedal free play. Adjustments

(4) Check pedal reserve distance. Adjustments

(5) Turn the Techstream on and enter the following menus: Chassis / ABS/VSC/ TRAC / Utility / Electronically Controlled Brake system Utility / Electronically Controlled Brake system Invalid to prohibit the brake control.

(6) Enter the following menus: Chassis / ABS/VSC/ TRAC / Data List "Master Cylinder Sensor", "Master Cylinder Sensor 2", "Stroke Sensor" and "Stroke Sensor 2".

(7) Check the value output from "Master Cylinder Sensor", "Master Cylinder Sensor 2", "Stroke Sensor" and "Stroke Sensor 2" by depressing the brake pedal.

Standard Voltage:





(8) Finish the brake control prohibition on the Techstream.

2. INSPECT STROKE SIMULATOR
