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.

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. ...
Brake pedal load sensing switch
Description
The brake pedal load sensing switch is turned on when the brake pedal is
depressed with force exceeding
a predetermined level.
The skid control ecu detects if the brake pedal is dep ...

Shift position purpose
*1: Shifting the shift lever to d allows the system to select a gear suitable
for
the driving conditions.
Setting the shift lever to d is recommended for normal driving.
*2: Selecting shift ranges using s mode restricts the upper limit of the
possible
gear ranges, controls engine bra ...
