Toyota RAV4 (XA40) 2013-2018 Service Manual: Master cylinder pressure sensor malfunction
Description
The master cylinder pressure sensor is connected to the skid control ecu in the abs and traction actuator.
Dtc c1281/81 can be detected when the master cylinder pressure sensor sends a master cylinder pressure signal or test mode ends. Dtc c1281/81 is output only in test mode.
Inspection procedure
Notice:
When replacing the abs and traction actuator, perform zero point calibration (see page bc-24).
- Read value of intelligent tester (stop light switch)
- Check the data list for proper functioning of the stop light switch.
Ok: on (brake pedal is depressed) appears on the screen.
- Read value of intelligent tester (master cylinder pressure sensor)
- Check the data list for proper functioning of the master cylinder pressure sensor.
Ok: when the pedal is depressed, the sensor output voltage increases.
- Reconfirm dtc
- Clear the dtc(s) (see page bc-47).
- Drive the vehicle at a speed of 30 km/h (18 mph) or more and perform a braking test (decelerate the vehicle by depressing the brake pedal).
- Check if the same dtc(s) is recorded (see page bc-47).
Result 
Replace abs and traction actuator assembly
