CLEAR DTC
Remark: If you clear the DTC (Diagnosis Trouble
Codes) you will not be able to read any codes
recorded during the last Trouble.
Remark: 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).

GOTHROUGH TECH2 CONNECTION.
(2) Push “F4” and answer “Yes” to the question “Do
you really want to clear the codes?”

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.
2

the recovery is done the TECH2 displays
“4L30E CODES CLEARED”.
2.

to terminal 4 or 5 (ground).

flashing.
