CONNECTOR SYMBOLS
Most of connector symbols in wiring diagrams are shown from the terminal side.
^ Connector symbols shown from the terminal side are enclosed by a single line and followed by the direction mark.
^ Connector symbols shown from the harness side are enclosed by a double line and followed by the direction mark.
^ Certain systems and components, especially those related to OBD, may use a new style slide-looking type harness connector.
^ Male and female terminals
Connector guides for male terminals are shown in black and female terminals in white in wiring diagrams.
Harness Indication
^ Connector numbers in a signal oval M33 indicate harness connectors.
^ Letter designations next to test meter probes indicate harness (connector) wire colors.
Component Indication
^ Connector numbers in a double oval F211 indicate component connectors.
SWITCH POSITIONS
Switches are shown in wiring diagrams as if the vehicle is in the "normal" condition.
A vehicle is in the "normal" condition when:
^ ignition switch is "OFF",
^ doors, hood and trunk lid/back door are closed,
^ pedals are not depressed , and
^ parking brakes is released.
DETECTABLE LINES AND NON-DETECTABLE LINES
In some wiring diagrams, two kinds of lines with different thicknesses are used to represent wires.
^ A line with regular thickness (wider line) represents a "detectable line for DTC (Diagnostic Trouble Code)". A "detectable line for DTC" is a circuit in which (ECM) (Engine control module) can detect malfunctions with the on-board diagnostic system.
^ A line with less thickness (thinner line) represents a "non-detectable line for DTC". A "non-detectable line for DTC" is a circuit in which ECM cannot detect malfunctions with the on-board diagnostic system.
MULTIPLE SWITCH
The continuity of multiple switch is described in two ways as shown below.
^ The switch chart is used in schematic diagrams.
^ The switch diagram is used in wiring diagrams.
