GLOW CONTROL SYSTEMPFP:25230
DescriptionEBS01KLM
SYSTEM DESCRIPTION
*: The output signal is sent from the ECM through CAN communication line.
When engine coolant temperature is more than approximately 80°C(176°F), the glow relay turns off.
When engine coolant temperature is lower than approximately 80°C(176°F):
lIgnition 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.
lCranking
The glow relay turns ON, allowing current to flow through glow plug.
lSta rti ng
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.

Diagnostic ProcedureEBS01KLO
1.INSPECTION START
Check fuel level, fuel supplying system, starter motor, etc.
OK or NG
OK >> GO TO 2.
NG >> Correct.
2.CHECK INSTALLATION
Check that glow plug nut (1) and all glow plug connecting plate nuts
(2) are installed properly.
OK or NG
OK >> GO TO 3.
NG >> Install properly.
3.CHECK GLOW INDICATOR LAMP OPERATION
With CONSULT-II
1. Turn ignition switch ON.
2. Select “COOLAN TEMP/S” in “DATA MONITOR” mode with
CONSULT-II.
3. Confirm that “COOLAN TEMP/S” indicates below 80°C(176°F).
If it indicates above 80°C(176°F), cool down engine.
4. Turn ignition switch OFF, wait at least 5 seconds and then turn
ON.
5. Make sure that glow indicator lamp is turned ON for 1.5 seconds
or more after turning ignition switch ON, and then glow indicator
lamp turned OFF.
Without CONSULT-II
1. Set the tester probe between ECM terminal 51 (engine coolant
temperature sensor signal) and ground.
2. Confirm that the voltage indicates above 1.53V. If it indicates
below 1.53V, cool down engine.
3. Turn ignition switch OFF, wait at least 5 seconds and then turn
ON.
4. Make sure that glow indicator lamp is turned ON for 1.5 seconds
or more after turning ignition switch ON, and then glow indicator
lamp turned OFF.
OK or NG
OK >> GO TO 4.

2. Confirm that “COOLAN TEMP/S” indicates approximately 25°C
(77°F). If NG, cool down engine.
3. Turn ignition switch OFF.
4. Set voltmeter probe between glow plug and engine body.
5. Turn ignition switch ON.
6. Check the voltage between glow plug and engine body under
the following conditions.

EGR VOLUME CONTROL SYSTEM
EGR VOLUME CONTROL SYSTEM
PFP:14710
DescriptionEBS01KLR
SYSTEM DESCRIPTION
*: This signal is sent to the ECM through CAN communication line.
This system controls flow rate of EGR led from exhaust manifold to intake manifold. The opening of the EGR
by-pass passage in the EGR volume control valve changes to control the flow rate. A built-in step motor
moves the valve in steps corresponding to the ECM output pulses. The opening of the valve varies for opti-
mum engine control. The optimum value stored in the ECM is determined by considering various engine con-
ditions.
The EGR volume control valve remains close under the following conditions.
lEngine stopped
lEngine starting
lLow engine coolant temperature
lExcessively high engine coolant temperature
lHigh engine speed
lAccelerator pedal fully depressed
COMPONENT DESCRIPTION
EGR Volume Control Valve
The EGR volume control valve uses a step motor to control the flow
rate of EGR from exhaust manifold. This motor has four winding
phases. It operates according to the output pulse signal of the ECM.
Two windings are turned ON and OFF in sequence. Each time an
ON pulse is issued, the valve opens or closes, changing the flow
rate. When no change in the flow rate is needed, the ECM does not
issue the pulse signal. A certain voltage signal is issued so that the
valve remains at that particular opening.
