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 can detect its malfunctions with
the on board diagnostic system.
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.
