Toyota RAV4 (XA40) 2013-2018 Service Manual: Communication
Description
The skid control ecu sends signals such as cruise control cancel demand signals and brake operation demand from ecm response signals to the ecm when the cruise control system is in operation.
Inspection procedure
Hint:
This circuit uses can communication. Therefore, if there are any malfunctions in the communication circuit, one or more dtcs in the can communication system are output.
- Check can communication system
Refer to how to proceed with troubleshooting (see page ca-8).
Description
Therefore, if the skid control ecu detects a communication error from the ecm, it sends a malfunction signal back to the ecm.
