DTC C1267/67 Brake Pedal Load Sensing Switch


DESCRIPTION

The 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.

DTC Code
DTC Detection Condition
Trouble Area
C1267/67
When one of the following conditions is met:
  1. An open or short in the brake pedal load sensing switch continues for 0.3 seconds or more.
  2. Immediately after the ignition switch is turned ON, the brake pedal load sensing switch is ON and the stop light switch is OFF for 10 seconds or more.
  3. While the vehicle speed changes from 0 km/h (0 mph) to 30 km/h (18 mph), the condition that the brake pedal load sensing switch remains ON occurs 5 times in succession.
  4. With the stop light switch ON, the brake pedal load sensing switch OFF, and the master cylinder pressure 6 MPa (61.2 kgf/cm2, 870 psi) or more, the deceleration is 0.4 G or more for 1 second or more.
  5. With the stop light switch ON, the brake pedal load sensing switch OFF, and the master cylinder pressure 6 MPa (61.2 kgf/cm2, 870 psi) or more, the vehicle speed is 0 km/h (0 mph) for 5 seconds or more.
  1. Brake pedal load sensing switch (Brake with switch pedal sub-assembly)
  2. Brake pedal load sensing switch circuit
  3. Skid control ECU (Brake actuator assembly)

INSPECTION PROCEDURE

NOTICE:
When replacing the brake actuator assembly, perform zero point calibration (Toyota Fortuner RM000000XHR02TX.html).
HINT:
When C1249/49 is output together with C1267/67, inspect and repair the trouble areas indicated by C1249/49 first (Toyota Fortuner RM000000XIE04EX.html).
1.READ VALUE USING INTELLIGENT TESTER (STOP LIGHT SWITCH AND BRAKE PEDAL LOAD SENSING SWITCH)

  1. Connect the intelligent tester to the DLC3.

  1. Select the Data List mode on the intelligent tester (Toyota Fortuner RM000000XHW03RX.html).

  1. Check that the stop light switch display and brake pedal load sensing switch display observed on the intelligent tester change according to brake pedal operation.

    OK:
    The intelligent tester displays ON or OFF according to brake pedal operation.

  1. Slowly depress the brake pedal, and check the illumination of the stop light switch and brake pedal load sensing switch.

    OK:
    First the stop light switch turns ON, and then the brake pedal load sensing switch turns ON.

2.RECONFIRM DTC

  1. Clear the DTC(s) (Toyota Fortuner RM000000XHV03YX.html).

  1. Start the engine.

  1. Perform a road test.

  1. Check if the same DTC is recorded (Toyota Fortuner RM000000XHV03YX.html).

NOTICE:
  1. Do not remove the brake pedal load sensing switch from the brake with switch pedal sub-assembly.
  2. When there is a malfunction in the brake pedal load sensing switch, replace the brake with switch pedal sub-assembly.

  1. Turn the ignition switch off.

  1. Make sure that there is no looseness at the locking part and the connecting part of the connector.

  1. Disconnect the brake pedal load sensing switch connector.

  1. Measure the resistance according to the value(s) in the table below.

    Standard Resistance:
    Tester Connection
    		Switch Condition
    		Specified Condition
    2 - 1
    		Brake pedal load sensing switch OFF
    (Brake pedal depressed)
    		950 to 1050 Ω
    2 - 1
    		Brake pedal load sensing switch ON
    (Brake pedal released)
    		203 to 223 Ω
