INFOID:0000000001703077
Specification data are reference values and are measured between each terminal and ground.
CAUTION:
Do not use ECM ground terminals when measuring input/output voltage. Doing so may result in dam-
age to the ECM's transistor. Use a ground other than ECM terminals, such as the ground.

• 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-detectable
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.
Multiple Switch
The continuity of multiple switch is described in two ways as shown below.
• The switch chart is used in schematic diagrams.
• The switch diagram is used in wiring diagrams.
