Toyota RAV4 (XA40) 2013-2018 Service Manual: 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).
Inspection procedure
- Perform active test by intelligent tester (motor relay)
- Select the active test, generate a control command, and then check that the abs motor relay operates.
Ok: operation sound of abs motor is heard.
- Reconfirm dtc
- Clear the dtc (see page bc-47).
- Start the engine.
- Drive the vehicle at a speed of 6 km/h (4 mph) or more for several seconds.
- Check if the same dtc is output (see page bc-47).
Result 
Replace abs and traction actuator assembly
- Inspect fuse (abs1)
- Remove the abs1 h-fuse from the engine room no. 1 Relay block.
- Measure the resistance of the fuse.
Standard resistance:
below 1 
- Check wire harness (skid control ecu - battery and body ground)
- Disconnect the a19 connector.
- Measure the resistance of the wire harness side connector.
Standard resistance 
- Measure the voltage of the wire harness side connector.

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 mo ...
