Is parameter displayed "Present fault"?
YES
▶ Go to "Terminal and connector inspection" procedure.
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
EC369B30
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 " Power Circuit Inspection " procedure.

VERIFICATION OF VEHICLE REPAIR
E279FF74
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 P0601 EEPROM-CHECK SUM ERROR
COMPONENT LOCATION
E229539F
PCM
SCMF16386L
GENERAL DESCRIPTION
E87E4D85
A malfunction is detected by using a checksum technique for verifying data. The digital data is composed of zeros and
ones. A checksum is the total of all ones in a string of data. By comparing the checksum value with a stored value, a
malfunction can be detected.
DTC DESCRIPTION
E65068E8
If real checksum does not accord with memory checksum, PCM sets P0601 and MIL(Malfunction Indication Lamp) turns
on.
DTC DETECTING CONDITION
E38A3627
Item
Detecting Condition
Possible cause
DTC Strategy
• Checksum check
Enable Conditions
• -
Threshold value
• Discordance between the real checksum and
the memorized checksum
Diagnosis Time
• Continuous
MIL On Condition
• 1 driving cycle
• Faulty PCM
MONITOR DTC STATUS
E7BDFDA8
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
