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

E0A64B5A

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.
