With TECH2 Scan Tool

NOTE: If you clear the DTC (Diagnostic Trouble Codes) you will not be able to read any codes recorded during the last occurrence.

NOTE: To use the DTC again to identify a problem, you will need to reproduce the fault or the problem. This may require a new test drive or just turning the ignition on (this depends on the nature of the fault).

1. IF you have a Tech2:
1. Connect the Tech2 if it is still not connected GOTHROUGH Tech2 OBD II CONNECTION.
2. Push "F4" and answer "Yes" to the question "Do you really want to clear the codes?"
a. When a malfunction remains as it is the Tech2 displays "4L30E CODES NOT CLEARED". This means that the problem is still there or that the recovery was not done. Please GOTO DTC CHECK.
b. When a malfunction has been repaired and the recovery is done. The Tech2 displays "4L30E CODES CLEARED".
