Toyota RAV4 (XA40) 2013-2018 Service Manual: Open in abs solenoid relay circuit
Description
The solenoid relay supplies power to the abs solenoid and trc solenoid.
After the ignition switch is turned on, the vehicle speed has reached 6 km/h (4 mph) and the solenoid is determined to be normal by the initial check self-diagnosis, the relay switches on. If any open or short circuits are detected, the relay switches off.
These dtcs may be set if the voltage supply to the solenoid relay (+bs) falls below the dtc detection threshold due to the battery or alternator outputs being insufficient.
Hint:
Dtcs c0278/11 and c0279/12: the skid control ecu begins to detect these dtcs when the vehicle speed exceeds 6 km/h (4 mph).
Wiring diagram
Refer to dtc c0273/13, c0274/14, c1361/91 (see page bc-79).
Inspection procedure
- Inspect fuses (abs2)
- Remove the abs2 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 ecu connector.
- Measure the voltage of the wire harness side connector.
Standard voltage 
- Measure the resistance of the wire harness side connector.
Standard resistance 
- Reconfirm dtc
- Clear the dtcs (see page bc-47).
- Start the engine.
- Drive the vehicle at 6 km/h (4 mph) or more to activate the initial check.
- Check if the same dtcs is output (see page bc-47).
Result 
Replace abs and traction actuator assembly
