TERMINAL AND CONNECTOR INSPECTION
E4982099
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?
FL -204
FUEL SYSTEM
YES
▶
Repair the trouble causing part and go to "Verification of Vehicle Repair".
NO
▶
Go to "Power Circuit Inspection".
POWER CIRCUIT INSPECTION
ED0A8269
1.
Check open in power circuit(High side)
1)
IG KEY "OFF", ENGINE "OFF".
2)
Disconnect injector connector and ECM connector.
3)
[P0201] Check continuity between injector #1 connector terminal 1 and ECM connector (C230-A) terminal 16.
[P0202] Check continuity between injector #2 connector terminal 1 and ECM connector (C230-A) terminal 2.
[P0203] Check continuity between injector #3 connector terminal 1 and ECM connector (C230-A) terminal 1.
[P0204] Check continuity between injector #4 connector terminal 1 and ECM connector (C230-A) terminal 17.
Specification : Continuity (below 1.0
Ω
)
4)
Is the measured resistance within the specification?
YES
▶
Go to "Control Circuit Inspection".
NO
▶
Repair open in injector #1 power circuit and go to "Verification of Vehicle Repair".
CONTROL CIRCUIT INSPECTION
E6A03E03
1.
Check open in control circuit(Low side)
1)
IG KEY "OFF", ENGINE "OFF".
2)
Disconnect injector connector and ECM connector.
3)
[P0201] Check continuity between injector #1 connector terminal 2 and ECM connector (C230-A) terminal 47.
[P0202] Check continuity between injector #2 connector terminal 2 and ECM connector (C230-A) terminal 31.
[P0203] Check continuity between injector #3 connector terminal 2 and ECM connector (C230-A) terminal 46.
[P0204] Check continuity between injector #4 connector terminal 2 and ECM connector (C230-A) terminal 33.
Specification : Continuity (below 1.0
Ω
)
4)
Is the measured resistance within the specification?
YES
▶
Go to "Component Inspection".
NO
DTC TROUBLESHOOTING PROCEDURES
FL -205
▶
Repair open in injector #1 control circuit and go to "Verification of Vehicle Repair".
COMPONENT INSPECTION
E25144D3
1.
Check injector component resistance
1)
IG KEY "OFF", ENGINE "OFF".
2)
Disconnect injector connector.
3)
Measure the resistance between injector component terminal 1 and 2.
Specification : 0.33
Ω
(20
℃
)
1
2
EGNG008I
4)
Is the measured resistance(of injector solenoid) within the specification?
YES
▶
Go to "Verification of Vehicle Repair".
NO
▶
Replace injector and go to "Verification of Vehicle Repair".
NOTE
Replacing injectors, peculiar IQA code of each injector should be inputted to ECM
Perform this process using "INJECTOR CORRECTION" function on scantool, Refer to P1670, P1671 for more de-
tailed information.
VERIFICATION OF VEHICLE REPAIR
E39AD433
After a repair, it is essential to verify that the fault is corrected.
1.
After connecting Scantool select "DIAGNOSTIC TROUBLE CODES(DTCs)" mode.
2.
Clear recorded DTC using Scantool.
3.
Drive the vehicle within DTC "Enable conditions" in "General information".
4.
After selecting "DIAGNOSTIC TROUBLE CODES(DTCs)" mode and check if DTC is recorded again.
5.
Are any DTCs recorded ?
YES
▶
Go to the DTC guide of recorded NO. in Scantool.
