FO:DATA LIST
The purpose of the FO: DATA LIST mode is to
continuously monitor data parameters.
The current actual values
of all important sensors
and signals in the system are displayed
through
Mode FO. The displayed actual values must then be
compared
with the specifications listed in the

Checking instructions. From these the trouble can
be clearly diagnosed.
In the Quick Check list, all the
test steps are summarized, so
that (for example),
after a mechanical/hydraulic problem, the electronic
functions can also be quickly checked.

F2:TROUBLE CODE
The purpose of the F2:TROUBLE CODE mode is to display stored Transmission Control Module (TCM)
trouble codes.
Selecting F2:TROUBLE CODE mode will cause the TECH 1 to display the trouble codes stored by the TCM.
The status
of the trouble code is displayed:
• PRESENT: Fault conditions present now.
• NOT PRESENT: Indicates a "History" trouble code: a code that was set but is no longer present.

The F3:SNAPSHOT mode provides you with a tool which you can use to help diagnose an intermittent or ~
transient problem. In this mode, you can specify a trigger condition, and TCM data is automatically stored
both before and after the trigger occurrence. You can then select any
of the stored data for display.

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).
1. IF you have a TECH1:
(1) Connect the TECH1 if it is still not con-
nected
GOTHROUGH TECH1 CON-
NECTION.
(2) Push "F4" and answer "Yes" to the
question
"Do you really want to clear the
codes?"
CD 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
DTCCHECK.
® When a malfunction has been re­
paired and the recovery is
done the
TECH1 displays "4L30E CODES
CLEARED".
2. IF you have no TECH1:
(
1) Short the Diagnosis Connector C-92 ter­
minal 1 to terminal 2 (ground) (Fig. 7A-
9c).
CD IF it is flashing and the flash is 0.4
seconds ON and 0.4 second OFF
without interruption, this means that
there is no DTC. The DTCs are
already cleared.
Fig. 7A-9c
AUTOMATIC TRANSMISSION (4L30-E) 7 A-65
(2) IF a code is flashed, wait until the lamp is
flashing.
(3) Push POWER SWITCH then WINTER
SWITCH
(do this within 3 second).
CD If you continue to have malfunctions:
This means that the problem is still
there or that the recovery was not
done please see DTC CHECK.
(4) IF you can not clear the DTC:
CD GOTHROUGH TCM PRECAUTIONS.
@ Disconnect the TCM.
@ Reconnect the TCM.
@ IF the DTC is not cleared: GOTO TCM
MEM-CAL REPLACEMENT.
