Toyota RAV4 (XA40) 2013-2018 Service Manual: 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.
Wiring diagram
Inspection procedure
Notice:
When replacing the brake actuator assembly, perform zero point calibration (see page bc-24).
Hint:
If dtc c1249/49 is output, repair it before repairing dtc c1267/67 based on the flowchart below.
- Read value of intelligent tester (brake pedal load sensing switch)
- Check the data list for proper functioning of the brake pedal load sensing switch.
Ok: on (brake pedal is depressed) appears on the screen.
- Inspect brake pedal load sensing switch
Notice:
- Do not remove the brake pedal load sensing switch from the brake pedal.
- When there is a malfunction in the brake pedal load sensing switch, replace the brake pedal.
- Turn the ignition switch off.
- Disconnect the brake pedal load sensing switch connector.
- Measure the resistance of the switch.
Standard resistance
- Check wire harness (skid control ecu - brake pedal load sensing switch)
- Disconnect the a19 ecu connector.
- Measure the resistance of the wire harness side connectors.
Standard resistance 
- Reconfirm dtc
- Clear the dtc (see page bc-47).
- Check if the same dtc is recorded (see page bc-47).
Result 
Use simulation method to check
Open in pump motor circuit
Description
The motor relay drives the pump motor based on a signal from the skid control
ecu.
Wiring diagram
Refer to dtc c0273/13, c0274/14, c1361/91 (see page bc-79).
