Work Procedure
1.SAVE ECM DATA
With CONSULT
NOTE:
>> GO TO 2.
2.CHECK ECM PART NUMBER
Check ECM part number to see whether it is blank ECM or not.
NOTE:
Is the ECM a blank ECM? YES >> GO TO 3.
NO >> GO TO 5.
3.SAVE ECM PART NUMBER
Read out the part number from the old ECM and save the number, following the programming instructions.
