Hyundai Santa Fe (2006 year). Manual — part 570
FLA -346
FUEL SYSTEM
▶ 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 injector and check for proper operation. If the problem is corrected, replace
injector and go to "Verification of Vehicle Repair" procedure.
NOTE
There is a memory reset function on scantool that can erase optional parts automatically detected and memorized
by PCM. After testing PCM on the vehicle, use this function to reuse the PCM on the others
VERIFICATION OF VEHICLE REPAIR
EEE753BC
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 ?
YES
▶ Go to the applicable troubleshoooting procedure.
NO
▶ System is performing to specification at this time.

DTC DESCRIPTION
E8A8A39D
Checking output signals from injectors.
Under detecting condition, if an output signal is high, PCM sets
P0262/P0265/P0268/P0271/P0274/P0277. MIL(Malfunction Indicatin Lamp) turns on when the malfunction lasts till
consecutive 2 driving cycle.
