Glow Control System
When coolant temperature is lower than 75°C (167°F):
●
Ignition switch ON
After ignition switch has been turned to ON, the glow relay
turns ON for a period of time depending on engine coolant
temperature, allowing current to flow through the glow plugs.
●
Starting
After starting the engine, current will flow through the glow
plugs for 300 seconds, or until the coolant temperature
exceeds 50°C (122°F).
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.
Malfunction is detected when .
