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.

FOLDOUT PAGE

Super multiple junction (SMJ)

In wiring diagram, connectors consistingofterminals havingterminal numbers withanalphabet (81,
DO, etc.) areSMJ connectors.
If connector numbersareshown inReference Area,these connector symbolsarenotshown inConnec-
tor Area. Forterminal arrangement ofthese connectors, refertothe foldout pageatthe end ofthis
manual.

Joint connector

Joint connector symbolsareshown inConnector Areainthe wiring diagram concerned. Foldoutpage
also carries
