Toyota RAV4 (XA40) 2013-2018 Service Manual: Tc and cg terminal circuit
Description
Connecting terminals tc and cg of the dlc3 causes the skid control ecu to display 2-digit dtcs by flashing the abs warning light.
Wiring diagram
Inspection procedure
- Check dlc3 (tc voltage)
- Turn the ignition switch on.
- Measure the voltage of the dlc3.
Standard voltage 
- Check can communication system
- Check the dtc (see page ca-34).
Result 
Replace abs and traction actuator assembly
- Check wire harness (dlc3 - ecm and body ground)
- Turn the ignition switch off.
- Disconnect the a12 ecm connector.
- Measure the resistance of the wire harness side connectors.
Standard resistance 
- Check wire harness (dlc3 - body ground)
- Measure the resistance of the dlc3.
Standard resistance 
- Check can communication system
- Check if the can communication dtc is output (see page ca-34).
Result 
Replace abs and traction actuator assembly

Steering angle sensor zero point malfunction
Description
The skid control ecu learns the steering sensor zero point every time the
ignition switch is turned on and
the vehicle is driven at 35 km/h (22 mph) or more for approximately 5 seconds.
The ecu also stores the
previous zero point.
If front wheel alignment or the steering wh ...

Intake air temperature circuit malfunction
Description
The intake air temperature (iat) sensor, mounted on the mass air flow (maf)
meter, monitors the iat.
The iat sensor has a built-in thermistor with a resistance that varies according
to the temperature of the
intake air. When the iat is low, the resistance of the thermist ...
