.
I

(connector) wire color.
I
Connector numbers in a single circle
M33
indicate harness con-
nectors.
Component indication
I
Connector numbers in a double circle indicate component con-
nectors.
SWITCH POSITIONS

DETECTABLE LINES AND NON-DETECTABLE LINES
In some wiring diagrams, two kinds of lines, representing wires,
with different weight are used.
I
A line with regular weight (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 its malfunctions with the on board diagnostic system.
I
A line with less weight (thinner line) represents a “non-detect-
able line for DTC”. A “non-detectable line for DTC” is a circuit
in which ECM cannot detect its malfunctions with the on board
diagnostic system.
