VERIFICATION OF VEHICLE REPAIR
E0179541
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.
