SIGNAL WAVEFORM AND DATA
EC4F06EA
Fig.1
Fig.2
Fig.1) Approx. 5% duty( (-)duty ) signal waveform of EEGR actuator (with EEGR valve closed)
Fig.2) Approx. 40% duty( (-)duty ) signal waveform of EEGR actuator(with EEGR valve opened)
SCMFL6285L
NOTE
The output of approx. 5% duty is mainly for the diagnosis of EEGR actuator circuit than actuating EEGR.
MONITOR SCANTOOL DATA
E29AB5B5
1.
Connect Scantool to Data Link Connector (DLC).
2.
Warm engine up to normal operating temperature.
3.
Turn "OFF" electrical devices and A/C.
4.
Monitor "AIR MASS PERCYLINDER" parameter on the Scantool.
Specification : When EEGR actuator does not operate 5% duty) at idle : 450mg/st ± 50 mg/st
When EEGR actuator operates(Approx. 45% duty) at idle : 400mg/st ± 50 mg/st
FL -288
FUEL SYSTEM
Fig.1
Fig.2
Fig.1) Check if "AIR MASS PERCYLINDER"l is 450mg/st 50mg/st without EEGR operation at warm idle
(EEGR actuator 5% duty)
Fig.2) Check if "AIR MASS PERCYLINDER"l is 400mg/st 50mg/st with EEGR operation at warm idle
(EEGR actuator approx. 45% duty)
SCMFL6391L
※
EEGR actuator operates as decelerating after rapid acceleration when idle EEGR does not operate, EEGR actuator
duty rises to approx. 45% at operating condition. This controlling process lasts for about 3 min. then EEGR actuator
turns "OFF" (duty 5% ).
NOTE
duty rises to approx. 45% at operating condition. This controlling process lasts for about 3 min. then EEGR actuator
turns "OFF" (duty 5% ).
TERMINAL AND CONNECTOR INSPECTION
E42512D6
1.
Electrical systems consist of a lot of harness and connectors, poor connection of terminals can cause various prob-
lems and damge of component.
2.
Perform checking procedure as follows.
1)
Check damage of harness and terminals : Check terminals for contact resistance, corrosion and deformation.
2)
Check connecting condition of ECM and component connector : Check terminal seperation, damage of locking
device and connecting condition between terminal and wiring.
NOTE
Disconnect the pin which requires checking at male connector and insert it to the terminal at female connector for
checking connecting condition. ( after checking, reconnect the pin at correct position. )
3.
Is the problem found?
YES
▶
Repair the trouble causing part and go to "Verification of Vehicle Repair".
NO
▶
Go to "Power Circuit Inspection".
DTC TROUBLESHOOTING PROCEDURES

POWER CIRCUIT INSPECTION
E8BFDA17
1.
Check power circuit voltage
1)
IG KEY "OFF", ENGINE "OFF"
2)
Disconnect EGR actuator connector
3)
IG KEY "ON"
4)
Measure the voltage of terminal 2 of EGR actuator connector.
Specification : 11.5V~13.0V
5)
Is the measured voltage within the specification?
YES
▶
Go to "Control Circuit Inspection".
NO
▶
Repair E/R FUSE
&
RELAY BOX 15A SENSOR #2 FUSE and related circuit and go to "Verification of Vehicle
Repair".
CONTROL CIRCUIT INSPECTION
E44292FB
1.
Check control circuit monitoring voltage
1)
IG KEY "OFF", ENGINE "OFF"
2)
Disconnect EGR actuator connector.
3)
IG KEY "ON"
4)
Measure the voltage of terminal 1 of EGR actuator connector.
Specification : 3.2V~3.7V
5)
Is the measured voltage within the specification?
YES
▶
Go to "Component Inspection".
NO
▶
When voltage is not detected : Go to "2. Check open in control circuit" as follows.
▶
When high voltage is detected : Repair short to battery and go to "Verification of Vehicle Repair".
2.
Check open in control circuit
1)
IG KEY "OFF", ENGINE "OFF"
2)
Disconnect EGR actuator connector and ECM connector
3)
Check continuity between EGR actuator terminal 1 and ECM connector (C230-A) terminal 59.
