NOTE: To be able 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 haveaTECH1:
(1) Connect the TECH1 if it is still not connected GOTHROUGH TECH1 OBD II CONNECTION.
(2) Push "F4" and answer "Yes" to the question "Do you really want to clear the codes?"
(1) When a malfunction remains as it is the TECH 1 displays "4L30E CODES NOT CLEARED". This means that the problem is still there or that the recovery was not done please GOTO DTC CHECK.
(2) When a malfunction has been repaired and the recovery is done the TECH1 displays "4L30E CODES CLEARED".
2. IF you have no TECH1:
To clear the DTC, remove Fuse "Stop, Air CONT" (C-14, 15A) for at least 10 seconds.
