MONITOR DTC STATUS
EBABB1E4
1.
Check DTC Status
1)
Connect scantool to Data Link Connector(DLC).
2)
IG "ON".
3)
Select "Diagnostic Trouble Codes(DTCs)" mode, and then Press F4(DTAL) to check DTC’s information from the
DTCs menu
4)
Read "DTC Status" parameter.
SCMF16159L
5)
Is parameter displayed "Present fault"?
YES
▶ Go to "Terminal and connector inspection" procedure.
DTC TROUBLESHOOTING PROCEDURES
FLA -471
NO
▶ Fault is intermittent caused by poor contact in the sensor’s and/or PCM’s connector or was repaired and PCM
memory was not cleared. Thoroughly check connectors for looseness, poor connection, ending, corrosion, con-
tamination, deterioration, or damage. Repair or replace as necessary and go to "Verification of Vehicle Repair"
procedure.
TERMINAL AND CONNECTOR INSPECTION
E49C836E
1.
Many malfunctions in the electrical system are caused by poor harness and terminals. Faults can also be caused by
interference from other electrical systems, and mechanical or chemical damage.
2.
Thoroughly check connectors for looseness, poor connection, bending, corrosion, contamination, deterioration, or
damage.
3.
Has a problem been found?
YES
▶ Repair as necessary and go to "Verification of Vehicle Repair" procedure
NO
▶ Go to " Control Circuit Inspection " procedure.
CONTROL CIRCUIT INSPECTION
E3BADF5F
1.
Check voltage
1)
IG "OFF".
2)
Disconnect ETS motor & TPS connector.
3)
IG "ON" and ENG "OFF"
4)
Measure the voltage between terminal 5,8 of ETS motor & TPS harness connector and chassis ground.
Specification : Approx. 12V
5)
Is the measured voltage within specification?
YES
▶ Go to "Component inspection" procedure.
NO
▶ Go to "Check open in harness" as follows.
2.
Open in control circuit inspection
1)
IG "OFF"
2)
Disconnect ETS motor & TPS connector and PCM connector.
3)
Measure the resistance between terminal 5 of ETS motor & TPS harness connector and terminal C30-B (2) of
PCM harness connector.
FLA -472
FUEL SYSTEM
4)
Measure the resistance between terminal 8 of ETS motor & TPS harness connector and terminal C30-B (1) of
PCM harness connector.
Specification : Approx. below 1Ω
5)
Is the measured resistance within specification ?
YES
▶ Go to "Component inspection" procedure.
NO
▶ Repair Open in motor harness and go to "Verification of Vehicle Repair" procedure.
COMPONENT INSPECTION
EC9FEB92
1.
Check throttle valve for stuck
1)
IG "OFF".
2)
Disconnect the air hose between throttle body and air mass flow sensor.
3)
Check stuck on throttle valve.
4)
Is the throttle valve normal?
YES
▶ Go to check "ETS motor resistance" as follows.
NO
▶ Repair or replace as necessary and go to "Verification of Vehicle Repair" procedure.
2.
Check ETS motor resistance
1)
IG "OFF".
2)
Disconnect ETS motor & TPS connector.
3)
Measure the resistance between terminal 5 and 8 of ETS motor & TPS connector(component side).
Specification : Approx. 1.275 ~ 1.725Ω @ 23℃ (73.4℉)
4)
Is the measured resistance within specification?
YES
▶ Go to "ETC motor actuation test" procedure.
NO
▶ Substitute with a known - good ETC motor and check for proper operation. If the problem is corrected, replace
ETC motor and go to "Verification of Vehicle Repair" procedure.
※ Procedure of ETS Initialization
DTC TROUBLESHOOTING PROCEDURES
FLA -473
1. Erase the trouble codes on PCM
2. Turn the ignition key off and keep this condition until the main relay is turned off.(It will takes 10 second)
3. Turn ignition key on more than 1second to record the throttle motor position on the EEPROM
3.
ETC motor actuation test
1)
IG "OFF".
2)
Connect ETS motor & TPS connector.
3)
After IG "ON", execute the "ETC motor actuation test" by Scantool.
EGRF926A
4)
Does the "ETC motor actuation test" execute normally?
YES
▶ Substitute with a known - good PCM and check for proper operation. If the problem is corrected, replace PCM
and go to "Verification of Vehicle Repair" procedure.
NO
▶ Substitute with a known - good ETC motor and check for proper operation. If the problem is corrected, replace
ETC motor and go to "Verification of Vehicle Repair" procedure.
※ Procedure of ETS Initialization
1. Erase the trouble codes on PCM
2. Turn the ignition key off and keep this condition until the main relay is turned off.(It will takes 10 second)
3. Turn ignition key on more than 1second to record the throttle motor position on the EEPROM
VERIFICATION OF VEHICLE REPAIR
EEB6DD19
After a repair, it is essential to verify that the fault has been corrected.
1.
Monitor and record the Freeze Frame Data for the Diagnostic Trouble Code(DTC) which has been diagnosed.
2.
Using a Scantool, Clear the DTCs
3.
Operate the vehicle within conditions noted in the freeze frame data or enable conditions
4.
Monitor that all rediness test have been verified as " Complete "
5.
Are any DTCs present ?
