Toyota RAV4 (XA40) 2013-2018 Service Manual: Master cylinder pressure sensor malfunction

Toyota RAV4. 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).

  1. Read value of intelligent tester (stop light switch)

  1. Check the data list for proper functioning of the stop light switch.

Ok: when the pedal is depressed, the sensor output voltage increases.



  1. Reconfirm dtc

  1. Clear the dtc(s) (see page bc-47).
  2. 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).
  3. Check if the same dtc(s) is recorded (see page bc-47).
