- Brake pedal load sensing switch
- Brake pedal load sensing switch circuit
- Brake actuator assembly (Skid control ECU)
DESCRIPTIONThe brake pedal load sensing switch is turned on when the brake pedal is depressed with force exceeding a predetermined level. The skid control ECU detects if the brake pedal is depressed or not via this circuit.
WIRING DIAGRAMCAUTION / NOTICE / HINTNOTICE: When replacing the brake actuator assembly, perform zero point calibration and store system information (See page ). HINT: When DTC C1425 and/or C1426 is output together with DTC C1429, inspect and repair the trouble areas indicated by DTC C1425 and/or C1426 first (See page , or ). PROCEDURE
(a) Connect the Techstream to the DLC3. (b) Turn the ignition switch to ON. (c) Turn the Techstream on. (d) Enter the following menus: Chassis / ABS/VSC/ TRAC / Data List. (e) Select the Data List on the Techstream (See page ). ABS/VSC/TRAC
(f) Check that the brake pedal load sensing switch display observed on the Techstream changes according to brake pedal operation. OK: The Techstream displays ON or OFF according to brake pedal operation.
(a) Turn the ignition switch off. (b) Clear the DTCs (See page ). (c) Start the engine. (d) Perform the road test. (e) Check if the same DTC is recorded (See page ). Result
