Toyota RAV4 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.
