DIAGNOSIS
ISOLATE NOISE
Identify the cause of any noise before attempting to repair
the clutch, the transaxle, or their related link–ages.
Symptoms of trouble with the clutch or the manual trans-
axle include:
S A great effort required to shift gears.
S The sound of gears clashing and grinding.
S Gear blockout.
Any of these conditions requires a careful analysis. Make
the following checks before disassembling the clutch or
the transaxle for repairs.
Road Travel Noise
Many noises that appear to come from the transaxle may
actually originate with other sources such as the:
S Tires.
S Road surfaces.
S Wheel bearings.
S Engine.
S Exhaust system.
These noises may vary according to the:
S Size of the vehicle.
S Type of the vehicle.
S Amount of insulation used in the body of the ve-
hicle.
Transaxle Noise
Transaxle gears, like any mechanical device, are not ab-
solutely quiet and will make some noise during normal op-
eration.
To verify suspected transaxle noises:
1. Select a smooth, level asphalt road to reduce tire
and resonant body noise.
2. Drive the vehicle far enough to warm up all the lu-
bricants thoroughly.
3. Record the speed and the gear range of the trans-
axle when the noise occurs.
4. Check for noises with the vehicle stopped, but with
the engine running.
5. Determine if the noise occurs while the vehicle op-
erates in:
S Drive – under a light acceleration or a heavy
pull.
S Float – maintaining a constant speed with a light
throttle on a level road.
S Coast – with the transaxle in gear and the
throttle partly or fully closed.
S All of the above.
Bearing Noise
Differential Side Bearing Noise
Differential side bearing noise and wheel bearing noise
can be confused easily. Since side bearings are pre–
loaded, a differential side bearing noise should not dimin-
ish much when the differential/transaxle is run with the
wheels off the ground.
Wheel Bearing Noise
Wheel bearings produce a rough growl or grating sound
that will continue when the vehicle is coasting and the
transaxle is in NEUTRAL. Since wheel bearings are not
pre–loaded, a wheel bearing noise should diminish con-
siderably when the wheels are off the ground.
Other Noise
Brinelling
A brinelled bearing causes a ”knock” or ”click” approxi-
mately every second revolution of the wheel because the
bearing rollers do not travel at the same speed as the
wheel. In operation, the effect is characterized by a low–
pitched noise.
A brinelled bearing is caused by excessive thrust which
pushes the balls up on the pathway and creates a triangu-
lar–shaped spot in the bearing race. A brinelled bearing
can also be caused from pressing one race into position
by applying pressure on the other race.
A false indication of a brinelled bearing occurs as a result
of vibration near the area where the bearing is mounted.
Brinelling is identified by slight indentations, resulting in a
washboard effect in the bearing race.
Lapping
Lapped bearing noise occurs when fine particles of abra-
sive materials such as scale, sand, or emery circulate
through the oil in the vehicle, causing the surfaces of the
roller and the race to wear away. Bearings that wear loose
but remain smooth, without spalling or pitting, are the re-
sult of dirty oil.
Locking
Large particles of foreign material wedged between the
roller and the race usually causes one of the races to turn,
creating noise from a locked bearing. Pre–loading regular
taper roller bearings to a value higher than that specified
also can result in locked bearings
Pitting
Pitting on the rolling surface comes from normal wear and
the introduction of foreign materials.
Spalling
Spalled bearings have flaked or pitted rollers or races
caused by an overload or an incorrect assembly that re-
sults in a misalignment, a cocking of bearings, or adjust-
ments that are too tight.
After completing these checks, refer to the ”Diagnosis
Chart” in this section.

SIR DIAGNOSTIC SYSTEM CHECK
Notice : If the vehicle interior has been exposed to exten-
sive water intrusion such as water leaks, driving through
high water, flooding, or other causes, the sensing and
diagnostic module(SDM) and SDM connector may need
to be replaced. With ignition OFF, inspect the area around
the SDM, including the carpet. If any significant soaking or
evidence of previous soaking is detected, the water must
be removed, water damage repaired, and the SDM and
the SDM connector must be replaced. Before attempting
any of these repairs, the supplemental inflatable re-
straints(SIR) must be disabled. Refer to ”Disabling the
SIR” and ”Sensing and Diagnostic Module(SDM)” in this
section for instructions on how to disable the SIR and re-
place the SDM.
The SIR Diagnostic System Check must always be the
starting point for any SIR diagnosis. The Diagnostic Sys-
tem Check reveals diagnostic trouble codes(DTCs)
through the use of scan tool. The diagnostic procedures
used in this section are designed to find any repair SIR
conditions. To get the best results, it is important to use the
diagnostic charts and follow the sequence listed below.
1. Perform the SIR Diagnostic System Check, which
reveal diagnostic trouble codes(DTCs) through theuse of scan tool.. It also checks for proper airbag
indicator operation.
2. Refer to the proper diagnostic chart as directed by
SIR Diagnostic System Check. Bypassing these
procedures may result in extended diagnostic time,
incorrect diagnosis, and incorrect parts replace-
ment.
3. Repeat the SIR Diagnostic System Check after any
repair or diagnostic procedures have been per-
formed to ensure that the repair has been made
correctly and that no other malfunction exists.
Circiut Description
When the ignition switch is first turned to ON, ignition volt-
age is supplied from airbag fuse to find the SDM at input
terminal A1. The SDM responds by flashing the airbag in-
dicator seven times and then turning it off while the SDM
performs tests on the SIR.
Diagnostic Aids
The order in which DTCs are diagnosed is very important.
Failure to diagnose the DTCs in the order specified may
result in extended diagnostic time, incorrect diagnosis,
and incorrect parts replacement.
SIR Diagnostic System Check
CAUTION : The sensing and the diagnosis module
(SDM) can maintain surfficient voltage to deploy the
airbags and pretensioners for 1 minute after the igni-
tion is OFF and the fuse has been removed. If the air-
bags and pretensioners are not disconnected, do not
begin service until one minute has been passed after
disconnecting power to the SDM. Otherwise, injury
could result.
CAUTION : During service procedure, be very careful
when handling the SDM. Never strike or jar the SDM.Never power the supplemental inflatable re-
straints(SIR) when the SDM is not rigidly attached to
the vehicle. All SDM mounting bolts must be carefully
tightened , and the arrow on the SDM must be point
toward the front of the vehicle to ensure proper op-
eration of the SIR. The SDM could be activated if it is
powered when it is not rigidly attached to the vehicle,
resulting in unexpected deployment and possible in-
jury.

SENSING AND DIAGNOSTIC MODULE (SDM) INTEGRITY
CHECK
The following diagnostic chart must be used when all cir-
cuitry outside the sensing and diagnostic module (SDM)
has been found to operate properly, as indicated by follow-
ing the appropriate diagnostic trouble code(DTC) chart.
The chart verifies the need for SDM replacement.
Circuit Description
When the SDM recognizes ignition voltage greater than 9
volts at terminal A1 of the SDM, the airbag indicator
flashes seven times to verify operation. At this time the
SDM performs turn–on tests followed by resistance mea-surement tests and continuous monitoring tests.
When malfunction is detected, the SDM sets current DTC
and illuminates the airbag indicator.
When the malfuncation is no longer detected and/or the
ignition switch is cycled, the SDM will clear current DTCs
and move them to a history file, except for the DTCs 51
and sometimes 71. DTCs 51 will not be cleared by scan
tool because these codes require replacement of SDM.
The SDM must be replaced only after the malfunction that
set the DTC has been repaired.
Sensing and Diagnostic Module (SDM) Integrity Check
CAUTION : The sensing and diagnostic module
(SDM) can maimtain sufficient voltage to deploy the
airbags and pretensioners for 1 minute after the igni-
tion is OFF and the fuse has been removed. If the air-
bags and pretensioners are not disconnected, do not
begin service until one minute has passed after dis-
connecting the power to the SDM. Otherwise, injury
could result.
CAUTION : During service procedure, be very careful
when handling the SDM. Never strike or jar the SDM.Never power the supplemental inflatable re-
straints(SIR) when the SDM is not rigidlyattached to
the vehile. All SDM mounting bolts must be carefully
tightened , and the arrow on the SDM must be point
toward the front of the vehicle to ensure proper op-
eration of the SIR. The SDM could be activated if it is
powered when it is not rigidly attached to the vehicle,
resulting in unexpected deployment and possible in-
jury.
