When engine coolant temperature is more than approximately
75ÉC (167ÉF), the glow relay turns off.
When coolant temperature is lower than approximately 75ÉC
(167ÉF):
+Ignition switch ON
After ignition switch has turned to ON, the glow relay turns ON
for a certain period of time in relation to engine coolant
temperature, allowing current to flow through glow plug.
+Cranking
The glow relay turns ON, allowing current to flow through glow
plug.
+Starting
After engine has started, current continues to flow through
glow plug (after-glow mode) for a certain period in relation to
engine coolant temperature.
The glow indicator lamp turns ON for a certain period of time in
relation to engine cooalnt temperature at the time glow relay is
turned ON.

COMPONENT DESCRIPTIONNLEC0760S02Glow PlugNLEC0760S0201The glow plug is provided with a ceramic heating element to obtain
a high-temperature resistance. It glows in response to a signal sent
from the ECM, allowing current to flow through the glow plug via
the glow relay.

ECM Terminals and Reference ValueNLEC0761Specification 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.
