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
Low battery positive voltage
Description
When there is an abnormality in the power supply circuit of the brake
actuator (skid control ecu), the skid
control ecu sets a dtc and the operation is prohibited by the fail-safe ...
Open in stop light switch circuit
Description
The skid control ecu detects the brake operating conditions through a signal
transmitted by the stop light
switch. The skid control ecu incorporates an open circuit detection circuit. ...

Perform vehicle stability control system recognition in ecm
Notice:
If the vehicle has both cruise control and vsc, when
replacing ecm, perform vsc recognition as follows:
Turn the ignition switch on.
After waiting approximately 5 seconds, turn the
cruise control main switch on.

Tire pressure warning light circuit
Description
If the tire pressure warning ecu detects trouble, the tire pressure warning
light turns on and tire pressure
monitor is canceled at the same time. At this time, the ecu records a dtc in
memory.
