Toyota RAV4 Service Manual: Communication

Toyota RAV4. 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.

  1. Check can communication system

Refer to how to proceed with troubleshooting (see page ca-8).
