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.
Problem symptoms table
When a "normal" code is output during a dtc check but the problem is still occurring, use the problem symptoms table. The suspected areas (circuits or parts) for each problem symptom are ...
