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).

Steering angle sensor zero point malfunction
Description
The skid control ecu learns the steering sensor zero point every time the
ignition switch is turned on and
the vehicle is driven at 35 km/h (22 mph) or more for approximately 5 sec ...

Removal
Hint:
Use the same procedures for the rh side and lh side.
The procedures listed below are for the lh side.
Remove front pillar cover sub-assembly upper lh
Using a moulding remover, detach the 3 clips and
remove the pillar cover.

Lost communication with front satellite sensor bus lh
Description
The front airbag sensor lh consists of the diagnostic circuit and the frontal
deceleration sensor.
If the center airbag sensor receives signals from the frontal deceleration
sensor, it determines whether or
not the srs should be activated.
