Detectable Lines and Non-Detectable Lines
In some wiring diagrams, two kinds of lines, representing wires with different weight are used.
^
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.
^
A line with less weight (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.
