5GI860DETECTABLE LINESANDNON-DETECTABLE LINES
In some wiring diagrams, twokinds oflines, representing
wires, withdifferent weightareused.
• Aline with regular weight(widerline)represents a"detect-
able lineforDTC (Diagnostic TroubleCode)".A"detectable
line forDTC" isacircuit inwhich ECM(ECCS control mod-
ule) candetect itsmalfunctions withtheon-board diagnos-
tic system.
• Aline with lessweight (thinner line)represents a"non-de-
tectable lineforDTC", A"non-detectable lineforDTC" isa
circuit inwhich ECMcannot detectitsmalfunctions withthe
on-board diagnostic system.
