1998 SSANGYONG MUSSO warning

0B-12 GENERAL INFORMATION
OWNER INSPECTIONS
AND SERVICES
WHILE OPERATING THE VEHICLE
Horn Operation
Blow the horn occasionally to make sure it works. Check
all the button locations.
Brake System Operation
Be alert for abnormal sounds, increased brake pedal
travel or repeated puling to one side when braking. Also,
if the brake warning light goes on, or flashes, something
may be wrong with part of the brake system.
Exhaust System Operation
Be alert to any changes in the sound of the system or
the smell of the fumes. These are signs that the system
may be leaking or overheating. Have the system
inspected and repaired immediately.
Tires, Wheels and Alignment Operation
Be alert to any vibration of the steering wheel or the
seats at normal highway speeds. This may mean a wheel
needs to be balanced. Also, a pull right or left on a
straight, level road may show the need for a tire pressure
adjustment or a wheel alignment.
Steering System Operation
Be alert to changes in the steering action. An inspection
is needed when the steering wheel is hard to turn or
has too much free play, or is unusual sounds are noticed
when turning or parking.
Headlight Aim
Take note of the light pattern occasionally. Adjust the
headlights if the beams seem improperly aimed.
AT EACH FUEL FILL
A fluid loss in any (except windshield washer) system
may indicate a problem. Have the system inspected and
repaired immediately.
Engine Oil Level
Check the oil level and add oil if necessary. The best
time to check the engine oil level is when the oil is warm.
1. After stopping the engine, wait a few minutes for the
oil to drain back to the oil pan.
2. Pull out the oil level indicator (dip stick).
3. Wipe it clean, and push the oil level indicator back
down all the way.
4. Pull out the oil level indicator and look at the oil level
on it.5. Add oil, if needed, to keep the oil level above the
lower mark. Avoid overfilling the engine, since this
may cause engine damage.
6. Push the indicator all the way back down into the
engine after taking the reading.
If you check the oil level when the oil is cold, do not run
the engine first. The cold oil will not drain back to the
pan fast enough to give a true oil level reading.
Engine Coolant Level and Condition
Check the coolant level in the coolant reservoir tank
and add coolant if necessary. Inspect the coolant.
Replace dirty or rusty coolant.
Windshield Washer Fluid Level
Check the washer fluid level in the reservoir. Add fluid if
necessary.
AT LEAST TWICE A MONTH
Tire And Wheel Inspection and Pressure
Check
Check the tire for abnormal wear or damage. Also check
for damaged wheels. Check the tire pressure when the
tires are cold ( check the spare also, unless it is a
stowaway). Maintain the recommended pressures. Refer
to “Tire and Wheel” is in section 0B.
AT LEAST MONTHLY
Light Operation
Check the operation of the license plate light, the
headlights (including the high beams), the parking lights,
the fog lights, the taillight, the brake lights, the turn
signals, the backup lights and the hazard warning flasher.
Fluid Leak Check
Periodically inspect the surface beneath the vehicle for
water, oil, fuel or other fluids, after the vehicle has been
parked for a while. Water dripping from the air
conditioning system after use is normal. If you notice
fuel leaks or fumes, find the cause and correct it at once.
AT LEAST TWICE A YEAR
Power Steering System Reservoir Level
Check the power steering fluid level. Keep the power
steering fluid at the proper level. Refer to
Section 6A,
Power Steering System.
Brake Master Cylinder Reservoir Level
Check the fluid and keep it at the proper level. A low
fluid level can indicate worn disc brake pads which may
need to be serviced. Check the breather hole in the
reservoir cover to be free from dirt and check for an
open passage.

2A-6 SUSPENSION DIAGNOSIS
DAMPING FORCE CONTROL LOGIC
Control Logic that applies on damping force variable suspension is comprised of road sensing driving comfort control
logic to increase driving comfort and vehicle speed sensing control logic, anti-roll control logic and anti-dive control
logic to secure control safety.

NORMAL CONTROL
Initial Stage
When ignition switch is "ON", system initialization will be performed for approx. 3 seconds. During this time, warning
lamp will stay ON and damping force will be switched to Hard status. After 3 seconds, warning lamp will turn off and
normal control status will be restored.
Normal Damping Force Control Establishment
Damping force will have Soft®Medium®Hard status in AUTO mode and Medium®Hard status in SPORT mode.
When double control items are satisfied at the same time it will be Hard®Medium®Soft in order.
Normal Damping Force Control Release
Control mode release will be "Hard®Medium®Soft"or "Medium®Soft". In case that returned from Hard status to
Medium status during control, it will be done after elapse of setting times. Returning from Medium status to Soft status
will be done immediately without delay.

Temperature Model:
ABD operation is a high thermal load for the brakes.
To avoid any damages at the brakes, the disk temperature is calculated with a mathematical model for each driven
wheel separately. After ignition on, the calculation starts with 30°C and then three different phases are evaluated
separately and added:
ABD operation, braking and coling phase.
If the temperature is highter than 500°C, ABD is disabled for this wheel.
It is permitted again, if the model has calculated down the 350°C.
Lamp Concepts:
The system is equipped with an ABD information lamp, which is blinking during ABD operation.
The activation of the EBD, ABS warning lamp and the ABD info lampo is summarized in the following table:

REBUILD WARNINGS
Prior to rebuilding a transmission system, the following warnings
are to be noted.
lEnsure that, before replacing a transmission the cooler
lines are flushed out to remove any debris. This can be
done by applying compressed air to the rear cooler line
forcing oil and any contaminants out of the front cooler
line.
lThe cooler flow should be checked after the transmission
has been fitted. With the front cooler line connected
and the rear line run into a suitable container, measure
the flow over 15 seconds with the vehicle idling in park.
lThe flow rate should exceed 1 liter in 15 seconds.
lBe wary of any situation where water enters the
transmission. This may result in fluid foaming and leaking
through the breather.
lEnsure that both earth straps (one at the batted terminal
and one on the vehicle body) are connected in the
vehicle before connecting the positive side of the
battery.
lFollow the throttle position calibration procedure in
section 7 of this manual if the powertrain control module
transmission control unit (PCM/TCU) is swapped.
DISASSEMBLY PROCEDURE
Transmission
Notice
Remove the inhibitor switch before washing the transmission
in solvent or hot wash.
It is assumed that the transmission fluid has been drained
when the transmission was removed from the
vehicle and that the ‘special tools’ quoted are available.
The transmission is dismantled in a modular fashion, and the
details of disassembly for each module are given under the
appropriate subject. Refer to table 9.10 in section 9.6 for details
of all special tools required when performing disassembly
procedures.
Technicians overhauling these transmissions will also require
a selection of good quality Torx bit sockets, in particular
numbers 30, 40 and 50, and an 8 mm,10 mm and 12 mm
double hex socket.
To disassemble the transmission, proceed as follows:
1. Remove the converter and the converter housing.
2. Mount the transmission on the bench cradle
No.0555-331895.
3. Remove the sump and the sump seal.
