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.

2B-4 WHEEL ALIGNMENT1. Perform wheel alignment preliminary inspection.
2. Check the brakes for dragging.
3. Road test the vehicle.Does the vehicle lead/pull?
1. Cross switch the front tire and wheel assemblies. 2. Road test the vehicle. Does the vehicle lead/pull? 1. Check the front wheel alignment. Is the alignment within specifications?
1. Compare the front camber and front caster to specifications.Are they within specifications?
1. Check the vehicle frame. Is the frame bent?
1. Straighten the frame. Is the repair complete?
1. The probable cause is the tires.
2. Switch the left front tire and wheel assembly with
the left rear tire and wheel assembly.
3. Road test the vehicle. Does the vehicle still lead/pull?
1. Switch the left front tire and wheel assembly with the left rear tire and wheel assembly and replace theleft front tire. Does the repair complete?
1. Switch the right front tire and wheel assembly with
the right rear tire and wheel assembly.
2. Road test the vehicle. Does the vehicle still lead/pull?
1. Switch the right front tire and wheel assembly with the right rear tire and wheel assembly and replace the right front tire. Is the repair complete? Action

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.

ANTILOCK BRAKE SYSTEM 4F-7
ABD SYSTEM DESCRIPTION
General: The Automatic Brake Differential Lock (ABD) is a traction system by means of brake intervention only, available in a low speed range (< 60kph). It workes on µ-split roads with sidewise different friction coefficients.
The spinning driven wheel is braked and the drive torque can be transferred to the wheel on the high- µ side.
During ABD active, the ABD information lamp is blinking.The temperature of the brakes is calculated by a mathematical model and ABD is switched passive if the calculated temperature is greater than a threshold value(500 °C).
ABD is permitted again, when the calculated temperature is less than 350 °C.
Control Algorithm: The input signals for the control algorithm are the filteredwheel speed signals from the ABS speed processing. With the speed difference of the driven wheels, the control deviation is calculated. If the control deviation exceeds a certain threshold value,
the wheel with the greater slip is braked actively. The threshold value depends on the vehicle speed:It is reduced with increasing vehicle speed down to a constant value.
Pressure Modulation: Depending on the control deviation and the wheel acceleration of the spinning wheel, pressure increase, hold and decrease are made.
The pressure modulation is done with the conventional control with the valves. ASV, USV, EV and AV according the the following table:
Speed Range: ABD is available in the speed range 60 kph.
Above 60 kph vehicle speed, ABD is passive. It is possible to initiate ABD operation up to a vehicle speed of 55kph.
