are present. Refer to the appropriate engine electrical
diagnostics to diagnose any DTCs that were set.
CAUTION: With the high pressure fuel system in
this vehicle, any residual contaminated fuel will be
removed very quickly. Shut off the engine immedi-
ately if signs of engine damage are noted.The engine should then be evaluated to determine
if the contaminated fuel has caused any damage to
the fuel system and/or engine. Indicators that the
fuel system has been damaged include the following:
²Unstable fuel rail pressure. This can manifest
itself as instability of idle speeds, excessive under-
shoot/overshoot at engine start-up, or excessive
undershoot/overshoot when the engine operating con-
ditions change. A typical engine response to a large
rail pressure undershoot would be a decrease in
engine speed or engine stall.
²Excessive noise from the engine. This could indi-
cate poor rail pressure control or the inability of the
injection system to inject the proper amount of fuel.
²Excessive smoke (black or white). This could
indicate the inability of the fuel system to inject the
proper amount of fuel.
NOTE: If any of these conditions are exhibited after
cleaning the fuel system, proceed to the appropri-
ate engine electrical diagnostic information. Repair
the fuel system and/or engine as necessary.

EMERGENCY RUNNING FUNCTION
In order to ensure a safe driving state and to pre-
vent damage to the automatic transmission, the TCM
control module switches to limp-home mode in the
event of critical faults. A diagnostic trouble code
(DTC) assigned to the fault is stored in memory. All
solenoid and regulating valves are thus de-energized.
The net effect is:
²The last engaged gear remains engaged.
²The modulating pressure and shift pressures
rise to the maximum levels.
²The torque converter lockup clutch is deacti-
vated.
In order to preserve the operability of the vehicle
to some extent, the hydraulic control can be used to
engage 2nd gear or reverse using the following pro-
cedure:²Stop the vehicle.
²Move selector lever to ªPº.
²Switch off engine.
²Wait at least 10 seconds.
²Start engine.
²Move selector lever to D: 2nd gear.
²Move selector lever to R: Reverse gear.
The limp-home function remains active until the
DTC is rectified or the stored DTC is erased with the
appropriate scan tool. Sporadic faults can be reset
via ignition OFF/ON.

VAAUTOMATIC TRANSMISSION NAG1 - SERVICE INFORMATION 21 - 5

3.2.5 TRANSMISSION OPERATION AND
SHIFT SCHEDULING
The transmission covered in this manual has
unique shift schedules depending on the tempera-
ture of the transmission oil. The transmission oil
temperature has a decisive effect on the shift qual-
ity of the transmission. The shift schedule is modi-
fied to extend the life of the transmission while
operating under extreme conditions and to improve
driver comfort by modifying shift schedules.
The transmission oil temperature is measured
with a Temperature Sensor on the NAG1 transmis-
sion. The Temperature Sensor is an integral com-
ponent of the Transmission Solenoid assembly. If
the Temperature Sensor is causing a problem, a
DTC will be set in the TCM.
The Transmission Temperature Sensor is wired in
series with the Park /Neutral (P/N) switch. The P/N
switch is also located in the transmission. The trans-
mission temperature is only read by the TCM when
the P/N switch closes while in the R, D position.
When the shifter lever is in the park or neutral
position, the P/N switch opens and the temperature
being displayed is Engine temperature.
AutoStick Feature (If equipped)
This feature allows the driver to manually shift the
transaxle when the shift lever is moved sideways to
the (+ / -) in position D to adjust the shift range.
3.2.6 TRANSMISSION ADAPTIVES -
INITIALIZE AND STORE
Initialize Adaptive -This TCM function should be
used when a new transmission has been placed in
the vehicle. This command will reset the TCM
adaptive to the factory setting.
Store Adaptive -This command should be used
after the vehicle has been test driven by the tech-
nician to store any learned adaptive changes that
occurred during the test drive. During normal op-
eration adaptive are updated every 10 minutes.
Using this command the latest adaptive will be
written to the TCM immediately.
3.3 DIAGNOSTIC TROUBLE CODES
Diagnostic trouble codes (DTC's) are codes stored
by the Transmission Control Module (TCM) and the
Shift Lever Assembly Module (SLA) to help diag-
nose Transmission and Shifter problems. They are
viewed using the DRBIIItscan tool.
Always begin by performing a visual inspection of
the wiring, connectors, cooler lines and the trans-
mission. Any obvious wiring problems or leaks
should be repaired prior to performing any diagnos-
tic test procedures. Some engine driveability prob-lems can be misinterpreted as a transmission prob-
lem. Ensure that the engine is running properly
and that no ECM DTC's are present that could
cause a transmission complaint.
If there is a communication K-ABS,Shifter or
K-TCM circuit problem, trouble codes will not be
accessible until the problem is fixed. The DRBIIIt
will display an appropriate message. The following
is a possible list of causes for a bus problem:
± open or short to ground/battery in K line
circuit.
± internal failure of any module or component
connected to the K line circuit
Each diagnostic trouble code is diagnosed by
following a specific testing sequence. The diagnostic
test procedures contain step-by-step instructions
for determining the cause of a transmission diag-
nostic trouble code. Possible sources of the code are
checked and eliminated one by one. It is not neces-
sary to perform all of the tests in this book to
diagnose an individual code. These tests are based
on the problem being present at the time that the
test is run.
If the TCM records a DTC that will adversely
affect the vehicles transmission, it will request (via
the communication bus) that the ECM illuminate
the Malfunction Indicator Lamp (MIL). All trans-
mission DTC's will be stored in the TCM.
3.3.1 ACTIVE (HARD) CODE
Any Diagnostic Trouble Code (DTC) that is set
whenever the system or component is monitored is
an Active code. This means that the problem is
there every time the TCM checks that system or
component. Some codes will set immediately at
start up and others will require a road test under
specific conditions to set the DTC. It must be
determined if a code is Active (repeatable) or Stored
(Intermittent) before attempting diagnosis.
3.3.2 STORED (INTERMITTENT) CODE
A diagnostic trouble code that is not there every
time the TCM checks the circuit or function is a
Stored (Intermittent) code. Problems that come and
go like this are the most difficult to diagnose, they
must be looked for under the specific conditions
that cause them. If the DTC is reset (after an
ignition cycle) the DTC will be set to Stored (Inter-
mittent) status. A DTC status can be9Active9or
9Stored9(Intermittent). Active is when the DTC is
present in the controller and the transmission is in
the particular mode of operation for that DTC.
Stored means that the DTC occurred at some point,
but is not currently present, or the conditions have
not been right to check for the presence of the
problem, when a DTC is classified as Stored (Inter-
mittent), no TCM reaction is required.

GENERAL INFORMATION

Emergency running function
If DTCs occur, safe-driving conditions must be re-
tained but full functionality of the transmission will
be limited to avoid damaging the automatic trans-
mission. In the event of certain DTCs the TCM
switches to emergency running. The TCM will store
the appropriate DTC codes and solenoids will be
de-energized (turned off)
The transmission effects will be:
²The last gear shifted remains in that position
²The modulating pressure and shift pressure in-
crease to maximum value
²The torque converter clutch is disengaged
(turned off)
Shifting manually after a DTC detection
NOTE: The vehicle can still be shifted
manually to 2nd or reverse gear.
To accomplish these shifts you must
Stop the vehicle
Turn the ignition off
Start the engine
Place the selector lever into D for 2nd gear
Place the selector lever into R for reverse gear
The emergency running function is retained until
the DTC is eliminated or the stored DTC code is
erased.
Stored (Intermittent) DTCs can be reset by cy-
cling the ignition switch
3.3.3 TROUBLE CODE ERASURE
Diagnostic Trouble Codes can be erased in two
ways. The first is to erase the DTC with the DRBIII
or scan tool. The second is if the DTC is no longer
present, the DTC is reset by the TCM (after an
ignition cycle), which will place the DTC in an
intermittent status (Stored DTC).
When there are no diagnostic trouble codes
stored in memory, the DRBIIItwill display
(NO DTC's DETECTED(
3.4 USING THE DRBIIIT
Refer to the DRBIIItuser's guide for instructions
and assistance with reading trouble codes, erasing
trouble codes, and other DRBIIItfunctions.
3.5 DRBIIITERROR MESSAGES
Under normal operation, the DRBIIItwill display
one of only two error messages:
± User-Requested WARM Boot
± User-Requested COLD Boot
If the DRBIIItshould display any other error
message, record the entire display and call the
S.T.A.R. Center.
3.5.1 DRBIIITDOES NOT POWER UP
(BLANK SCREEN)
If the LED's do not light or no sound is emitted at
start up, check for loose cable connections or a bad
cable. Check the vehicle battery voltage. A mini-
mum of 11 volts is required to adequately power the
DRBIIIt.
If all connections are proper between the DRBI-
IItand the vehicle or other devices, and the vehicle
battery is fully charged, an inoperative DRBIIIt
may be the result of faulty cable or vehicle wiring.
For a blank screen, refer to the appropriate Body
Diagnostic manual.
3.5.2 DISPLAY IS NOT VISIBLE
Low temperatures will affect the visibility of the
display. Adjust the contrast to compensate for this
condition.
