COLUMN, OR INSTRUMENT PANEL COMPONENT
DIAGNOSIS OR SERVICE. DISCONNECT AND ISO-
LATE THE BATTERY NEGATIVE (GROUND) CABLE,
THEN WAIT TWO MINUTES FOR THE AIRBAG SYS-
TEM CAPACITOR TO DISCHARGE BEFORE PER-
FORMING FURTHER DIAGNOSIS OR SERVICE. THIS
IS THE ONLY SURE WAY TO DISABLE THE AIRBAG
SYSTEM. FAILURE TO TAKE THE PROPER PRE-
CAUTIONS COULD RESULT IN ACCIDENTAL AIR-
BAG DEPLOYMENT AND POSSIBLE PERSONAL

lbs.).
(3) Remove the plugs or tape from the heater core
tube fittings and both heater core ports.
(4) Position both heater core tubes and the sealing
plate simultaneously to the heater core supply and
return ports.
(5) The heater core tubes each have a slot that
must be indexed to a location tab within each of the
heater core ports. Adjust the position of the tubes as
required so that the sealing plate fits flush against
the heater core supply and return ports, which indi-
cates that the tubes are properly indexed.
(6) Install and tighten the screw that secures the
heater core tube sealing plate to the heater core sup-
ply and return ports. Tighten the screw to 3 N´m (27
in. lbs.).

cles in the two lower finger formations of the evapo-
rator housing near the dash panel (Fig. 17).
(8) Install and tighten the three screws that secure
the heater core shield to the left end of the HVAC
distribution housing. Tighten the screws to 2 N´m (17
in. lbs.).(9) Reconnect the power brake booster input rod
(push rod) to the pin on the brake pedal arm. (Refer

HEATER HOSE
REMOVAL
There are several heater core plumbing configura-
tions used on this model, depending upon the engine
size and other optional equipment. One plumbing
configuration is used for all 2.4L engines (Fig. 21),
while the 3.3L and 3.8L engines have unique heater
return plumbing on the engine for models with or
without an optional engine oil cooler (Fig. 24) or (Fig.
25). There are also unique plumbing configurations
at the heater core for models with or without the
optional rear heater and air conditioner (Fig. 22) or
(Fig. 23). All models use a combination of formed
steel tubing and rubber hoses. In most cases, the
rubber hose is secured to the steel tubing with a
spring tension clamp.
WARNING: REFER TO THE APPLICABLE WARN-
INGS AND CAUTIONS FOR THIS SYSTEM BEFORE
PERFORMING THE FOLLOWING OPERATION.
(Refer to 24 - HEATING & AIR CONDITIONING/
PLUMBING FRONT - WARNING - HEATER PLUMB-
ING).
(1) Drain the engine cooling system. (Refer to 7 -
COOLING - STANDARD PROCEDURE - COOLING
SYSTEM DRAIN).
(2) Using spring tension clamp pliers, compress
and slide the clamps that secure each end of the
heater hose to the tube or nipple toward the center of
the hose to be removed. Release the clamp when it is
off of the tube or nipple.

DRIVEABILITY - GAS

> Quick Learn should generally not be used as a
repair procedure unless directed by a repair or
diagnostic procedure. If the transmission system
is exhibiting a problem that you think is caused
by an invalid CVI, you should try to relearn the
value by performing the appropriate driving ma-
neuver. In most cases, if a quick learn makes a
vehicle shift better, the vehicle will return with
the same problem.
> Before performing Quick Learn, it is imperative
that the vehicle be shifted into OD with the
engine running and the oil level set to the correct
level. This step will purge air from the clutch
circuits to prevent erroneous clutch volume val-
ues which could cause poor initial shift quality.
> If an unused TCM is installed on a vehicle with a
HOT engine, Quick Learn will cause the TCM to
report a cold calculated oil temperature. This
requires monitoring the calculated oil tempera-
ture using the DRBIIIt. If the temperature is
below 15C (60É F), the transmission must be run
at idle or driven in gear until it goes above 15C
(60ÉF). If the temperature is above 93C (200ÉF),
the transmission must cool to below 93C (200ÉF).
> First gear is engaged in overdrive after Quick
Learn is completed. Place the vehicle in park
after performing Quick Learn.
The Quick Learn function should be performed:
± Upon installation of a new service TCM
± After replacement or rebuild of internal trans-
mission components or the torque converter
± If one or more of the clutch volumes indexes
(CVI's) contain skewed readings because of
abnormal conditions.
To perform the Quick Learn procedure, the fol-
lowing conditions must be met.
± It is imperative that the vehicle be shifted into
OD with the engine running and the oil level
set to the correct level. This step will purge the
air in the clutch circuits to prevent erroneous
clutch volume values, which could cause poor
initial shift quality.
± The brakes must be applied.
± The engine must be idling.
± The throttle angle (TP sensor) must be less
than 3 degrees.
± The shift lever position must stay in neutral
until prompted to shift into OD.
± The shift lever must stay in OD after the9Shift
to Overdrive9prompt until the DRBIIItindi-
cates the procedure is complete.
± The oil temperature must be between 15C
(60ÉF) and 93C (200ÉF).NOTE:The above conditions must be maintained
during the procedure to keep the procedure from
being aborted.
The Quick Learn procedure is performed with the
DRBIIItby selecting9Transmission9system then
9Miscellaneous9functions, then9Quick Learn9. Follow
the procedure instructions displayed on the DRBIIIt.
3.3.9 CLUTCH VOLUMES
The L-R clutch volume is updated when doing a
2-1 or 3-1 coast down shift. The transmission tem-
perature must be between 21-49C (70-120É F). The
clutch volume should be between 35 and 83.
The 2-4 clutch volume is updated when doing a
1-2 shift. The transmission temperature must be
above 43C (110ÉF). The clutch volume should be
between 20 and 77.
The OD clutch volume is updated when doing a
2-3 shift. The transmission temperature must be
above 43C (110ÉF). The clutch volume should be
between 40 and 150.
The UD clutch volume is updated when doing a
4-3 or 4-2 shift. The transmission temperature must
be above 43C (110ÉF). The clutch volume should be
between 24 and 70.
3.3.10 ELECTRONIC PINION FACTOR
The transmission output speed signal supplies
distance pulses to the powertrain control module
(PCM), which are used to calculate speed and
mileage. A pinion factor is stored in the transmis-
sion control module (TCM) in order to provide the
appropriate distance pulses for the vehicle. The
pinion factor is programmed into the TCM at the
assembly plant.
Using the following steps, the pinion factor can be
checked and/or reset using the DRBIIIt:
1. Select Transmission system, then Miscellaneous
functions, then Pinion Factor. The DRBIIItwill
display the current tire size.
2. If the tire size is incorrect, depress the Enter key
and then select the correct size.
3. Depress the Page Back key to exit the reset
procedure.
Notes About Electronic Pinion Factor Features
The nature of the electronic pinion factor requires that
certain features must be taken into consideration.
> If no pinion factor is stored in an installed TCM,
the vehicle speedometer will not operate, engine
speed will be limited to 2300 RPM, and catalyst
damage may occur.
> Selecting a wrong tire size will cause the speed-
ometer to be inaccurate and will also cause any
speed related features to operate improperly.
Note: After replacing the TCM, you must
reprogram pinion factor
