When engine coolant temperature is more than approximately 75ÉC
(167ÉF), the glow relay turns off, inactivating the quick-glow control
until coolant temperature drops below approximately 55ÉC (131ÉF).
When coolant temperature is lower than approximately 75ÉC
(167ÉF):
I
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.
I Cranking
The glow relay turns ON, allowing current to flow through glow
plug.
I 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.
When engine speed exceeds approximately 4,800 rpm, current
flow through glow plug is interrupted.
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
I 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.
I This engine uses two types of glow plugs.
Type A has a blue or yellow paint mark.
Type B has no paint mark.
The location of the paint mark is shown in the figure.
WARNING:
Do not use two types of glow plugs at the same time.

SYSTEM DESCRIPTION
This system improves acceleration when the air conditioner is used.
When the accelerator pedal is fully depressed, the air conditioner is turned off for a few seconds. When engine
coolant temperature becomes excessively high, the air conditioner is turned off. This continues until the cool-
ant temperature returns to normal.

IPre-glow
When the ignition switch is turned on the ON position, the glow
indicator lamp will turn ON and pre-glow starts.
The glow relay is turned ON continuously. The ON time of both
the glow indicator lamp and the glow relay is determined by the
engine coolant temperature. Pre-glow ends when the pre-glow
time elapses or when the engine is started.
I Intermediate glow
Intermediate glow starts when the pre-glow time has elapsed
and the engine has not been started. The glow relay is turned
ON intermittently. Intermediate glow ends when the intermedi-
ate glow time has elapsed, or when the engine is started.
I After-glow
After-glow starts as soon as the engine is running and the
engine coolant temperature is below 50ÉC (122ÉF). The glow
relay is turned on continuously. After-glow ends when the after-
glow time elapses, or when the engine coolant temperature
exceeds 50ÉC (122ÉF).
