HOW TO USE THIS MANUAL
 Letter designations next to test meter probe indicate harness (con-nector) wire color.
 Connector numbers in a single circle M33 indicate harness con-
nectors.
Component Indication
Connector numbers in a double circle 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 brake is released.
Detectable Lines and Non-Detectable Lines
In some wiring diagrams, two kinds of lines, r epresenting wires, with different weight are used.
