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 (ECCS 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.
