MONITOR SCANTOOL DATA
EE6C6BF4
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 "INLET THROTTLE ACTUATOR." parameter on the Scantool.
Specification : 4.7% duty outputted except the operation of throttle flap
95% duty outputted at the operation of throttle flap
Fig.1
Fig 1) The duty of "INLET THROTTLE ACTUATOR." is 4.7% at IG KEY "ON" and ENGINE "ON".
The duty of "INLET THROTTLE ACTUATOR." is 95% at the point of turning IG KEY "OFF".

※
Monitoring if the state of throttle control actuator changes at turning engine OFF because the communication
through Scantool is comleted 3 sec. after turning engine ON. It is the easiest way to check if throttle control actu-
ator is closed for about 1 sec. and opened again with eyes(visually) or ears(sound) in order to inspect component
operation.
TERMINAL AND CONNECTOR INSPECTION
ED3A94F2
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".

CONTROL CIRCUIT INSPECTION
E0C9A313
1.
Check control circuit voltage
1)
IG KEY "OFF", ENGINE "OFF"
2)
Disconnect Throttle control actuator connector.
3)
IG KEY "ON"
4)
Measure the voltage of Throttle control actuator connector terminal 2.
specification : 0.0V~0.1V
5)
Is the measured voltage within the specification?
YES
▶
Go to "2.Check open in control circuit".
NO
▶
Repair short to battery in control circuit and go to "Verification of Vehicle Repair".
2.
Check open in control circuit
1)
IG KEY "OFF", ENGINE "OFF"
2)
Disconnect Throttle control actuator connector and ECM connector.
3)
Check continuity between throttle control actuator connector terminal 2 and ECM connector (C230-K) terminal
90.
specification : Continuity (below 1.0
Ω
)
4)
Is the measured resistance within the specification? (Is continuity confirmed?)
YES
▶
Go to "3. Check short to ground in control circuit" as follows.
NO
▶
Repair open in throttle control actuator control circuit and go to "Varification of Vehicle Repair".
3.
Check short to ground in control circuit
1)
IG KEY "OFF", ENGINE "OFF"
2)
Disconnect Throttle control actuator connector.
3)
Check continuity between throttle control actuator connector terminal 2 and chassis ground.
specification : Discontinuity (Infinite
Ω
)
4)
Is the measured resistance within the specification? (Is control circuit insulated with ground?)
YES
DTC TROUBLESHOOTING PROCEDURES
FL -481
▶
Go to "Ground Circuit Inspection".
NO
▶
Repair short to ground in control circuit and go to "Verification of Vehicle Repair".
GROUND CIRCUIT INSPECTION
ED251993
1.
IG KEY "OFF", ENGINE "OFF"
2.
Disconnect Throttle control actuator connector.
3.
IG KEY "ON"
4.
Measure the voltage of Throttle control actuator connector terminal 3. [ TEST "A" ]
5.
Measure the voltage between Throttle control actuator connector terminal 3 and 4. [ TEST "B" ]
( terminal 3 : Check + prove , terminal 4 : Check - prove )
Specification : [TEST "A"] Voltage - [TEST "B"] Voltage = below 200mV
6.
Is the measured voltage within the specification?
YES
▶
Go to "Component Inspection".
NO
▶
When "B" voltage is not detected : Repair open in ground circuit(G15 ground point related circuit) and go to
"Verification of Vehicle Repair".
▶
When the voltage difference between "A" and "B" is above 200mV : Eliminate the causes of excessive resistance
and go to "Verification of Vehicle Repair".
COMPONENT INSPECTION
EA699941
1.
Throttle control actuator component visual inspection
1)
IG KEY "OFF", ENGINE "OFF"
2)
Disconnect intake hose connected to throttle control actuator.
3)
Check if throttle control actuator is contaminated with carbon fraction.
4)
Check if throttle flap moves smoothly as touching it with hand (perform this process at IG KEY "OFF" state.)
※
Check if abnormal noise, valve shaft stuck, too much wear are detected.
Specification : Flap moves smoothly and carbon fraction, too much wear, abnormal noise are not detected.
5)
