4.
Is the measured resistance at certain temperature within the specified resisance range at the temperature?
YES
▶ Go to "Verification of Vehicle Rapair".
NO
▶ Replace FTS and go to "Verification of Vehicle Rapair".
VERIFICATION OF VEHICLE REPAIR
EDABB9FE
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.
NO
▶ System operates within specification.

Specification : 4.8V~5.1V
5)
Is the measured voltage within the specification?
YES
▶ Go to "Ground Circuit Inspection".
NO
▶ Go to "2.Check open in signal circuit" as follows.
2.
Check open in signal circuit
1)
IG KEY "OFF", ENGINE "OFF".
2)
Disconnect FTS connector and ECM connector.
3)
Check continuity between FTS connector terminal 2 and ECM connector terminal 11.
FLA -190
FUEL SYSTEM
Specification : Continuity (below 1.0Ω )
4)
Is the measured resistance within the specification?
YES
