With PGM Tester/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 TECH-2:
1. Connect the TECH-2 if it is still not connected GOTHROUGH TECH-2 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 TECH-2 displays "4L30E CODES NOT CLEARED". This means that the problem is still there or that the recovery was not done. Please GOTO OTC CHECK.
b. When a malfunction has been repaired and the recovery is done the TECH-2 displays "4L30E CODES CLEARED".
