Description
EBS015CE
SYSTEM DESCRIPTION
When engine coolant temperature is more than approximately 80
°
C (176
°
F), the glow relay turns off.
When coolant temperature is lower than approximately 80
°
C (176
°
F):
●
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 coolant temperature at the
time glow relay is turned ON.
COMPONENT DESCRIPTION
Glow Plug
The 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.
