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.
NG >> GO TO 5.

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.

lBefore installing, remove carbon depositing on mounting hole of glow plug with a reamer.
6. Install engine coolant temperature sensor.
7. Install in the reverse order of removal.
INSPECTION AFTER INSTALLATION
Inspection for Leaks
The following are procedures for checking fluids leak, lubricates leak and exhaust gases leak.
lBefore starting engine, check oil/fluid levels including engine coolant and engine oil. If less than required
quantity, fill to the specified level. Refer toMA-14, "
RECOMMENDED FLUIDS AND LUBRICANTS".
lUse procedure below to check for fuel leakage.
–Turn ignition switch “ON” (with engine stopped). With fuel pressure applied to fuel piping, check for fuel
leakage at connection points.
–Start engine. With engine speed increased, check again for fuel leakage at connection points.
lRun engine to check for unusual noise and vibration.
lWarm up engine thoroughly to make sure there is no leakage of fuel, exhaust gases, or any oil/fluids
including engine oil and engine coolant.
lBleed air from lines and hoses of applicable lines, such as in cooling system.
lAfter cooling down engine, again check oil/fluid levels including engine oil and engine coolant. Refill to the
specified level, if necessary.
Summary of the inspection items:
*1: Transmission/transaxle/CVT fluid, power steering fluid, brake fluid, etc.
