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

Test mode procedure
Hint:
By switching the skid control ecu from normal mode to
test mode, abnormality detection sensitivity is enhanced
and troubleshooting can be conducted efficiently.
Perform a sensor check in test mode after the speed
sensor or sensor rotor has been repaired or replaced.
