Toyota RAV4 (XA40) 2013-2018 Service Manual / Introduction / How to troubleshoot ecu controlled systems / How to proceed with troubleshooting / Circuit inspection

A description of the main areas of each circuit inspection is below.

Item	Description
description	The major role, operation of the circuit and its component parts are explained.
Dtc no., Dtc detection condition, trouble area	Indicates the diagnostic trouble codes, diagnostic trouble code detection conditions, and trouble areas of a problem.
Wiring diagram	This shows a wiring diagram of the circuit. Use this diagram together with electrical wiring diagram to thoroughly understand the circuit.
Inspection procedures	Use the inspection procedures to determine if the circuit is normal or abnormal. If abnormal, use the inspection procedures to determine whether the problem is located in the sensors, actuators, wire harnesses or ecu.
Inspection procedure connector illustrations	Connector being checked is connected: connections of tester are indicated by (+) or (-) after the terminal name. Connector being checked is disconnected: for illustrations of inspections between a connector and body ground, information about the body ground is not shown in the illustration.
