SUSPENSION DIAGNOSIS 2A-5
INPUT & OUTPUT DEVICES AND DAMPING FORCECONTROL LOGIC
INPUT & OUTPUT DEVICES Damping force of shock absorber will rotate shock absorber control rod in 3 modes by driving actuator on the upper shock absorber when signaled from ECS. Rotary valve in the shock absorber will control hydraulic flow according to rotation of control rod to adjust damping force of shock absorber in SOFT MEDIUM HARD.

Removal & Installation Procedure
1. Remove the stop lamp switch connector.
2. Remove the clevis pin and disconnect the brake boosterpush rod. Notice
Install in the upper hole (1), in case of Mando brake and
in the below hole (2), incase of PBR brake.
Install the snap pin fully in the hole of clevis pin.
Apply the grease around the hole of clevis pin.
3. Loosen the nut (4EA) and bolt (2EA) and remove the brake pedal.
4. Installation should follow the removal procedure in reverse order.
Tightening Torque 8 - 18 Nm

HYDRAULIC BRAKES 4A-11
Adjustment Procedure
1. Pedal HeightNotice If pedal height is not in specified value, loosen the stop lamp nut (B) and adjust the pedal height.
2. Pedal Stroke
Height (A) 150 mm (From the carpet)
Notice If pedal stroke is not in specified value, loosen the stop bolt and lock nut (F) and adjust the pedal stroke.
3. Free Play
Stroke (C) Mando : 138 mm
PBR : 132mm
Notice
To adjust, depress the brake pedal several times until there is no more vacuum left in the vacuum line.
To adjust, loosen the lock nut (D) of the push rod and turn the rod.
Free Play (E) 1 - 4 mm
Inspection Procedure
1. Inspect the wear of bushing.
2. Inspect the warp and bend of brake pedal.
3. Inspect the return spring of brake pedal.
4. Inspect the conductivity when connecting the tester to the stop lamp switch connector.

Phenomenon “4L ” lamp on cluster continuous blinking and can not go off,
when operated 4H/4L switch as 4L « 4H.
CauseShifting failure.
1. Stop the vehicle
2. Return the 4H/4L switch to first position (before
operating).
- The blinking of 4L indicator lamp is stopped.
NoteIf the first position before switch operating is ‘4L ’ ,
lamp goes on after stopping blink, otherwise it is ‘4H ’ lamp goes off.
3. Reoperate 4H/4L switch to 4H 4L on the below
condition. Positioned Auto T/M to neutral.
 At this time, keep the neutral position for 2 second.
 Stop the vehicle (The R.P.M of front & Rear propeller
shaft is below 80).
4. ‘4L ’ lamp blinks based on 0.3 second.
5. When the shifting is engaged, the blinking of ‘4L ’ lamp
is stopped.
-4H 4L : goes on ‘4L ’ lamp
-4L 4H : goes on ‘4L ’ lamp
6. When the ‘4L ’ indicator lamp continuous blinking,
repositioned to first position and diagnose the system and then fix it. Ye s
