Brake System Inspection
This inspection should be done when the wheels are re-
moved for rotation. Inspect the lines and the hoses for
proper hookup, binding, leaks, cracks, chafing, etc. In-
spect the disc brake pads for wear. Inspect the rotors for
surface condition. Inspect other brake parts, the parking
brake, etc., at the same time. Inspect the brakes more
often if habit or conditions result in frequent braking.
Steering, Suspension and Front Drive Axle
Boot And Seal Inspection
Inspect the front and rear suspension and the steering
system for damaged, loose or missing parts, signs of
wear or lack of lubrication. Inspect the power steering
line and the hoses for proper hookup, binding, leaks,
cracks, chafing, etc. Clean and inspect the drive axle
boot and seals for damage, tears or leakage. Replace
the seals if necessary.
Exhaust System Inspection
Inspect the complete system (including the catalytic
converter if equipped). Inspect the body near the ex-
haust system. Look for broken, damaged, missing, or
out -- of -- position parts as well as open seams, holes,
loose connections, or other conditions which could
cause heat buildup in the floor pan or could let exhaust
fumes seep into the trunk or passenger compartment.
Throttle Linkage Inspection
Inspect the throttle linkage for interference or binding,
damaged, or missing parts. Lubricate all linkage joints
and throttle cable joints, the intermediate throttle shaft
bearing, the return spring at throttle valve assembly, and
the accelerator pedal sliding face with suitable grease.
Check the throttle cable for free movements.
Engine Drive Belts
Inspect all belts for cracks, fraying, wear and proper ten-
sion. Adjust or replace the belts as needed.
Hood Latch Operation
When opening the hood, note the operation of the sec-
ondary latch. It should keep the hood from opening all
the way when the primary latch is released. The hood
must close firmly.
AT LEAST ANNUALLY
Lap and Shoulder Belts Condition and Operation
Inspect the belt system including: the webbing, the
buckles, the latch plates, the retractor, the guide loops
and the anchors.
Movable Head Restraint Operation
On vehicles with movable head restraints, the restraints
must stay in the desired position.
Spare Tire and Jack Storage
Be alert to rattles in the rear of the vehicle. The spare
tire, all the jacking equipment, and the tools must be se-
curely stowed at all times. Oil the jack ratchet or the
screw mechanism after each use.
Key Lock Service
Lubricate the key lock cylinder.
Body Lubrication Service
Lubricate all the body door hinges including the hood,
the fuel door, the rear compartment hinges and the
latches, the glove box and the console doors, and any
folding seat hardware.
Underbody Flushing
Flushing the underbody will remove any corrosive mate-
rials used for ice and snow removal and dust control. At
least every spring clean the underbody. First, loosen the
sediment packed in closed areas of the vehicle. Then
flush the underbody with plain water.
Engine Cooling System
Inspect the coolant and freeze protection fluid. If the
fluid is dirty or rusty, drain, flush and refill the engine
cooling system with new coolant. Keep the coolant at
the proper mixture in order to ensure proper freeze
protection, corrosion protection and engine operating
temperature. Inspect the hoses. Replace the cracked,
swollen, or deteriorated hoses. Tighten the clamps.
Clean the outside of the radiator and the air conditioning
condenser. Wash the filler cap and the neck. Pressure
test the cooling system and the cap in order to help en-
sure proper operation.

13. Remove the hydraulic pipe of power steering.
Notice:Completely drain the oil.
14. Discharge the refrigerant from A/C system, and dis-
connect the discharge pipe and suction pipe from
the compressor. Refer toSection 7B, Manual Con-
trol Heating, Ventilation, and Air Conditioning Sys -
tem.
15. Remove the fuel feed and return line.
Notice:Before removing the fuel lines, release the pres-
sure in the fuel system.

TROUBLE CODE DIAGNOSIS - DIESEL VEHICLE
TCM DIAGNOSTIC SYSTEM
OVERVIEW
Notice: To prevent Transmission Control Module (TCM)
damage. The ignition key must be OFF when
disconnection or reconnection the power to the TCM
(for example bttery cable, TCM pigtail connector, TCM
fuse, jumper cables, etc.).
When the TCM detects a system fault, a Diagnostic
Trouble Code (DTC) is set in the TCM. This code is
present while the fault conditions are met and is storedas a ‘History DTC’ until cleared. Condition for setting
and clearing each TCM DTC are provided in the relevant
sections.CLEARING TROUBLE CODES
TCM DTCs should be cleared after repairs have been
completed. Some diagnostic tables will tell you to clear
the codes before using the chart, which will help to
find the cause of the problem more quickly. Always
note the DTCs present before clearing - this information
may be helpful in the diagnostic process.

5A-78 AUTOMATIC TRANSMISSION
SSANGYONG MY2002
Circuit Description
The Air Conditioning Switch circuit indicates the state
of the air conditioning compressor clutch (on or off).
This signal is available to the TCM only on vehicles
fitted with air conditioning.
The DTC 1710 sets when an intermittent connection in
the air conditioning switch circuit has been detected.
The switch input is rapidly changing states and the
switching frequency is greater than 8.3 Hz.
Conditions for Setting the DTC
The mode switching frequency is greater than 8.3
Hz.
The above condition must be continuously present
for 4 state changes.
Action Taken When the DTC Sets
The TCM does not compensate for torque variation
due to air conditioning compressor clutch activation.
DIAGNOSTIC TROUBLE CODE (DTC) P1710
AIR CONDITIONING SWITCH CIRCUIT MALFUNCTION
Conditions for Clearing the DTC
The DTC will clear after 3 seconds without the fault.
A history DTC will clear after 40 TCM power-up
cycles with a warm transmission (>50 °C) and
without a fault.
History DTCs can be cleared by using a scan tool.
Diagnostic Aids
This fault is caused by too many changes in the
mode input signal over a period of time.
Typical causes would be an intermittent connection
in the switch or wiring or an intermittent short to
ground in the wiring.
