STEERING COLUMN COMPONENT SERVICE
The Acustar tilt and standard steering columns
(Fig.1) have been designed to be serviced as an as-
sembly; less wiring, switches, shrouds, steering
wheel, etc. Also most steering column components
can be serviced without removing the steering col-
umn from the vehicle. For additional information on
electrical components refer to Group 8H Electrical.
GEAR SHIFT LEVER
The gear shift lever (if equipped) is a serviceable
component of the Acustar steering column assembly.
REMOVE (1) Support the steering column assembly as
shown in (Fig. 1) using a suitable size socket. (2) Using a drift of the appropriate size drive the
roll pin out of the steering column and gear shift le-
ver (Fig. 1). Remove the gear shift lever from the
steering column assembly.
INSTALL (1) Support the steering column assembly as
shown in (Fig. 1) using a suitable size socket. (2) Install the gear shift lever into the steering col-
umn assembly. Align the roll pin holes in the gear
shift lever and the steering column assembly. (3) Carefully Install the roll pin into the steering
column assembly and through the shift lever. If the
roll pin binds check the alignment on the holes. Be
sure roll pin is fully installed into the steering col-
umn assembly.
IGNITION SWITCH SERVICE
TEST AND REPAIR
If the ignition switch effort seems to be excessive
due to binding. Follow the procedure outlined below
to determine the cause.
When service procedures are performed on the
Acustar steering column there are certain areas of the
column that can not be tampered with. If a problem re-
lated to these areas of the steering column are detected.
The entire steering column (less the removable compo-
nents) should be replaced see (Fig. 2 and 3).
(1) Remove ignition switch from steering column.
Refer to Group 8H Electrical.
(2) Using a key cylinder, check the turning effort
of the switch.
² If the ignition switch binds look for the following
conditions.

SPEED SENSOR-OUTPUT
CAUTION: When disconnecting speed sensor con-
nector, be sure that the weather seal does not fall
off or remain in old sensor. The output speed sensor is located to the left of the
manual shift lever (Fig. 8).
TRANSMISSION CONTROL MODULE
When replacing a transmission control module, do
not interchange transmission control modules with
previous year transmission control modules. If a
same year transmission control module is being used
from a different vehicle, the following procedures
must be performed before operating the transaxle:
² Quick Learn Procedure
² Torque Converter Clutch Break-in Procedure
² Electronic Pinion Procedure
The transmission control module is located on the
passenger side of the engine compartment. It is held
in place by four mounting screws. If the transmission control module has been
replaced, the following procedures must be per-
formed:
² ``Quick Learn Procedure''. This procedure will al-
low the transmission control module to learn the
characteristics of the vehicle.
² ``Electronic Pinion Procedure''. This procedure will
reprogram settings within the transmission control
module to compensate for different tire sizes and fi-
nal drive ratios.
² ``Converter Clutch Break-In Procedure'' This proce-
dure will reset the torque converter clutch status.
REMOVAL AND INSTALLATION
(1) Loosen 60 way retaining screw, located in the
center of the 60 way connector. Then disconnect the
60 way connector on transmission control module. (2) Remove transmission control module mounting
screws and lift module from vehicle. To install, reverse removal procedure.
TRANSAXLE QUICK LEARN PROCEDURE
The quick learn procedure requires the use of the
DRB II scan tool and the 1993 DRB II scan tool car-
tridge. This program allows the electronic transaxle sys-
tem to recelebrate itself to provide the best possible
transaxle operation. The quick learn procedure
should be performed if any of the following proce-
dures are performed:
² Transaxle Assembly Replacement
² Transmission Control Module Replacement
² Solenoid Pack Replacement
² Clutch Plate and/or Seal Replacement
² Valve Body Replacement or Recondition
(1) Plug the DRB II scan tool into the blue CCD
Buss connector. The connector is located under the
instrument panel on the drivers side of the vehicle. (2) Insert the 1993 DRB II scan tool cartridge into
the DRB II scan tool. (3) The red and green lights on the DRB II scan
tool will light up and then begin flashing. Wait until
the lights stop flashing before continuing with this
procedure. (4) Press the number 4 key on the DRB II scan
tool key pad. Item number 4 will not appear on the
DRB II scan tool screen unless you scroll down. It is
not necessary to scroll down to be able to choose item
4. (5) Press the number 2 on the DRB II scan tool
key pad (Transmission). (6) Press the number 1 on the DRB II scan tool
key pad. Wait for the DRB II scan tool to perform the

(7) Press the number 5 on the DRB II scan tool
key pad (Adjustments). (8) Press the number 3 on the DRB II scan tool
key pad (Quick Learn). Then follow the instructions
on the DRB II scan tool screen.
PINION FACTOR PROCEDURE
The vehicle speed readings for the speedometer are
taken from the output speed sensor. Because of dif-
ferent tire sizes and final drive ratios, the transmis-
sion control module must be calibrated to reflect the
different combinations of equipment. A procedure has
been developed called Pinion Factor. It allows the
technician to set the transmission control module ini-
tial setting so that the speedometer readings will be
correct. Failure to perform this procedure will cause a ``No
Speedometer Operation'' condition. This procedure must be performed if the transmis-
sion control module has been replaced. To properly read or reset the Pinion Factor, it is
necessary to use a DRB II scan tool. Perform the fol-
lowing steps with the DRB II scan tool to read or re-
set the Pinion Factor: (1) Plug the DRB II scan tool into the blue CCD
Bus connector. The connector is located under the in-
strument panel on the drivers side of the vehicle. (2) Insert the 1993 DRB II scan tool cartridge into
the DRB II scan tool. (3) The red and green lights on the DRB II scan
tool will light up and then begin flashing. Wait until
the lights stop flashing before continuing with this
procedure. (4) Press the number 4 key (Select System) on the

(7) Press the number 5 on the DRB II scan tool
key pad (Adjustments). (8) Press the number 2 on the DRB II scan tool
key pad (Pinion Factor). Then follow the instructions
on the DRB II scan tool screen.
TORQUE CONVERTER CLUTCH BREAK-IN
PROCEDURE
A torque converter clutch break-in program is be-
ing used on all models with a 41TE. This program
will properly condition the torque converter clutch. This will eliminate shudder during partial torque
converter clutch operation on a new torque converter.
If the torque converter is replaced, the new clutch
within the torque converter will require break-in.
The current break-in status stored in the transmis-
sion control module will have to be reset to the start
of break-in with the DRB II scan tool. If a new transmission control module is put on the
vehicle, the status will be at the start of break-in.
This status is acceptable regardless of the mileage on
the torque converter. No modification of the break-in
status is required. To properly service these vehicles, it is necessary to
use a DRB II scan tool to read or reset the break-in
status. Perform the following steps with the DRB II
scan tool to reset the break-in status: (1) Plug the DRB II scan tool into the blue CCD
Bus connector. The connector is located under the in-
strument panel on the drivers side of the vehicle. (2) Insert the 1993 DRB II scan tool cartridge into
the DRB II scan tool. (3) The red and green lights on the DRB II scan
tool will light up and then begin flashing. Wait until
the lights stop flashing before continuing with this
procedure. (4) Press the number 4 key (Select System) on the
DRB II scan tool key pad. Item number 4 will not ap-
pear on the DRB II scan tool screen unless you scroll
down. It is not necessary to scroll down to be able to
choose item 4. (5) Press the number 2 on the DRB II scan tool
key pad (Transmission). (6) Press the number 1 on the DRB II scan tool

BODY DIAGNOSTIC PROCEDURES INDEX

Water Leaks ............................. 2 Wind Noise.............................. 3
WATER LEAKS
Water leaks can be caused by poor sealing, improper
body component alignment, body seam porosity, miss-
ing plugs, or blocked drain holes. Centrifugal and
gravitational force can cause water to drip from an
area somewhat distant from the actual leak point,
making leak detection difficult. All body sealing points
should be water tight in normal wet driving conditions.
Water flowing downward from the front of the vehicle
should not enter the passenger or luggage compart-
ment. Moving sealing surfaces will not always seal
water tight under all conditions. At times, side glass,
door, or convertible top seals will allow water to enter
the passenger compartment during high pressure
washing or hard driving rain (severe) conditions. Over
compensating on door, glass, or top adjustments to stop
a water leak that occurs under severe conditions, can
cause premature seal wear and excessive closing or
latching effort. After a repair procedure has been
performed, water test vehicle to verify leak has stopped
before returning vehicle to use.
VISUAL INSPECTION BEFORE WATER LEAK TESTS
Verify that floor and body plugs are in place, body
drains are clear and body components are aligned and
sealed. If component alignment or sealing is necessary,
refer to the appropriate section of this group for proper
procedures.
WATER LEAK TESTS
WARNING: DO NOT USE ELECTRIC SHOP LIGHTS
OR TOOLS IN WATER TEST AREA, PERSONAL IN-
JURY CAN RESULT.
When a determination has been made on the condi-
tions that a water leak occurs, simulate the conditions
as closely as possible.
² If a leak occurs when the car is parked in a steady
light rain, flood the leak area with a open ended garden
hose.
² If a leak occurs at highway speeds in a steady rain,
test the leak area with a stream or fan spray of water
from a garden hose with an adjustable nozzle. Direct
the spray in the direction comparable to actual condi-
tions. ²
If a leak seems to occur only when the vehicle is
parked on an incline, hoist the end or side of the vehicle
to simulate this condition before water testing. This
method can also be used when the leak occurs when the
vehicle accelerates, stops, or turns. If the leak occurs
on acceleration, hoist the front of the vehicle. If the
leak occurs when braking, hoist the back of the vehicle.
If the leak occurs on left turns, hoist the left side of the
vehicle. If the leak occurs on right turns, hoist the right
side of the vehicle. For hoisting recommendations refer
to Group 0, Lubrication and Maintenance, General
Information section.
WATER LEAK DETECTION
To detect a water leak point of entry, perform a water
test and watch for water tracks or droplets forming on
the inside if the vehicle. If necessary remove interior
trim covers or panels to gain visual access to the leak
area. If the hose can not be positioned without being
held, have someone help perform the water test. Some water leaks must be tested for a considerable
length of time to become apparent. When a leak ap-
pears, determine the highest point of the water track or
drop. The highest point usually will indicate the point
of entry. After leak point has been determined, repair
the leak and water test to verify that leak has stopped. Locating the entry point of water that is leaking into
a cavity between panels can be difficult. The trapped
water splashes or runs from the cavity it is dammed up
in, often at a distance from the entry point. Most water
leaks of this type become apparent after accelerating,
stopping, turning, or when on a incline.
MIRROR INSPECTION METHOD
When a leak point area is visually obstructed, use a
suitable mirror to gain visual access. A mirror can also
be used to deflect light to a limited access area to assist
in locating a leak point.
BRIGHT LIGHT LEAK TEST METHOD
Some water leaks in the luggage compartment can be
detected without water testing. Position the vehicle in
a brightly light area. From inside the darkened lug-
gage compartment inspect around seals and body
seams. If necessary, have a helper direct a drop light
over the suspected leak areas around the lug-
