DTC P1217 OVERHEAT (COOLING SYSTEM)PFP:00021
DescriptionEBS004QR
SYSTEM DESCRIPTION
The ECM controls the cooling fan corresponding to the vehicle speed, engine coolant temperature, air condi-
tioner ON signal. The control system has 3-step control [HIGH/LOW/OFF].
OPERATION
CONSULT-II Reference Value in Data Monitor ModeEBS004QS
Specification data are reference values.
ECM Terminals and Reference ValueEBS004QT
Specification data are reference values and are measured between each terminal and ground.
CAUTION:
Do not use ECM ground terminals when measuring input/output voltage. Doing so may result in dam-
age to the ECM's transistor. Use a ground other than ECM terminals, such as the ground.
On Board Diagnosis LogicEBS004QU
This diagnosis continuously monitors the engine coolant temperature.
If the cooling fan or another component in the cooling system malfunctions, engine coolant temperature will
rise.

DTC P1217 OVERHEAT (COOLING SYSTEM)
When the engine coolant temperature reaches an abnormally high temperature condition, a malfunction is
indicated.
CAUTION:
When a malfunction is indicated, be sure to replace the coolant following the procedure in theMA-27,
"Changing Engine Coolant". Also, replace the engine oil.
1. Fill radiator with coolant up to specified level with a filling speed of 2 liters per minute. Be sure to
use coolant with the proper mixture ratio. Refer toMA-19, "
Engine Coolant Mixture Ratio".
2. After refilling coolant, run engine to ensure that no water-flow noise is emitted.
Overall Function CheckEBS004QV
Use this procedure to check the overall function of the cooling fan. During this check, a DTC might not be con-
firmed.
WAR NIN G:
Never remove the radiator cap when the engine is hot. Serious burns could be caused by high pres-
sure fluid escaping from the radiator.
Wrap a thick cloth around the cap. Carefully remove the cap by turning it a quarter turn to allow built-
up pressure to escape. Then turn the cap all the way off.
WITH CONSULT-II
1. Check the coolant level in the reservoir tank and radiator.
Allow engine to cool before checking coolant level.
If the coolant level in the reservoir tank and/or radiator is below
the proper range, skip the following steps and go toEC-764,
"Diagnostic Procedure".
2. Confirm whether customer filled the coolant or not. If customer
filled the coolant, skip the following steps and go toEC-764,
"Diagnostic Procedure".
3. Turn ignition switch “ON”.
4. Perform “COOLING FAN” in “ACTIVE TEST” mode with CON-
SULT-II and make sure that cooling fans operate when touching
“HIGH” or “LOW”.
If NG, go toEC-764, "
Diagnostic Procedure".

DTC P1510 ACCELERATOR PEDAL RELEASED POSITION SWITCHPFP:18002
DescriptionEBS0096V
The accelerator work unit is installed on the upper end of the accelerator pedal assembly. The accelerator
pedal position sensor 1, 2 and accelerator pedal released position switch are built into the accelerator work
unit. The sensor detects the accelerator pedal position and sends a signal to the ECM. The ECM uses the sig-
nal to determine the amount of fuel to be injected.
The accelerator pedal released position switch detects accelerator pedal released position signal and sends
this signal to the ECM. The ECM will then determine engine idle conditions. This signal is also used for diag-
nosing the accelerator pedal position sensor.

ECM Terminals and Reference ValueEBS0096X

CAUTION:
Do not use ECM ground terminals when measuring input/output voltage. Doing so may result in dam-
age to the ECM's transistor. Use a ground other than ECM terminals, such as the ground.

GLOW CONTROL SYSTEM
GLOW CONTROL SYSTEM
PFP:25230
DescriptionEBS0035J
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):
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 rting
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.
ECM Terminals and Reference ValueEBS0035K
Specification data are reference values and are measured between each terminal and ground.
CAUTION:
Do not use ECM ground terminals when measuring input/output voltage. Doing so may result in dam-
age to the ECM's transistor. Use a ground other than ECM terminals, such as the ground.

EGR VOLUME CONTROL SYSTEMPFP:14710
DescriptionEBS0035N
SYSTEM DESCRIPTION
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
lWide open throttle
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.
