DESCRIPTION
The EBD system (Electronic Brake force Distribution) as a sub- system of the ABS system is to control the effective
adhesion utilization by the rear wheels.
It further utilizes the efficiency of highly developed ABS equipment by controlling the slip of the rear wheels in the
partial braking range.
The brake force is moved even closer to the optimum and controlled electronically, thus dispensing with the need for
the proportioning valve.
The proportioning valve, because of a mechanical device, has limitations to achieve an ideal brake force distribution
tothe rear wheels as well as to carry out the flexible brake force distribution proportioning to the vehicle load or weight
increasing. And in the event of malfunctioning, driver cannot notice whether it fails or not.
EBD controlled by the ABS Control Module, calculates the slip ratio of each wheel at all times and controls the brake
pressure of the rear wheels not to exceed that of the front wheels.
If the EBD fails, the EBD warning lamp (Parking brake lamp) lights up.
ADVANTAGES
a.Function improvement of the base - brake system.
b. Compensation for the different friction coefficients.
c. Elimination of the proportioning valve.
d. Failure recognition by the warning lamp.

MODULE INTRODUCTION
FAM/IPM/RAM consists of a power board and an electronic board. The power board contains circuit protection devices
and switching devices. The electronic board uses Intelligent Power Switching (IPS) for HS/LS load control, logic
functions and CAN/K- Line communication. The power board and electronic board are connected with pin blocks for
the Front Area Module (FAM) and VCD (Variable Connection Displacement) for the In- Panel Module (IPM) and the
Rear Area Module (RAM).
switch, the status of the ABS EBD warning, the status of the brake fluid sensor and the speed of the vehicle.
The IPM sends the park brake indicator control on the CAN network.
The indicator is lighted if the vacuum switch or ABS EBD warning are on or brake fluid sensor is low or park brake
switch is on.
If the speed of the vehicle is over 10 km/h and ignition switch is on the status RUN the park brake indicator control is
blinking at 50% duty in 0.6 second if Parking Brake switch Input is active. In this case Vacuum switch, ABS EBD
warning and Brake Fluid sensor are ignored.
The park brake indicator is blinking on the same time that the chime is ringing. If a CAN signal among Vacuum switch,
EBD warning or Brake Fluid Sens switch is INVALID, out of range or not received this CAN signal is considered to be
OFF.
If VehicleSpeed CAN signal is INVALID or not received, it is considered to be 0 kph.
Charging Voltage Control
The IPM receives on analog input the voltage of generator and sends a warning.
When the voltage of generator L pass strictly above 10V, the state of the CAN variable.
Turn Indicators Status
The status of the turn indicators are sent on the CAN network when the CAN network is available.
High Beam Status
The status of the high beam is sent on the CAN network when the CAN network is available.
Front Fog Lamp Status
The status of the front fog lamp (lightning and state of the bulbs) is sent on the CAN network when the CAN network
is available.
Doors Open Warning
The RAM receives on digital input the status of the driver door open switch and sends it on the CAN network.
The RAM receives on digital input the status of the passenger door open switch and sends it on the CAN network.
The RAM receives on digital input the status of the left sliding door open switch and sends it on the CAN network.
The RAM receives on digital input the status of the right sliding door open switch and sends it on the CAN network.
When vehicle speed is under 10 kph, with ignition key not inserted and any door OPEN, DoorsOpenWngCtrl stays ON
for 20 min and then is turned OFF.
Tailgate Open Switch Status
When vehicle speed is under 10 kph, ignition key is inserted and Tailgate open switch is OPEN, Tailgate Open
warning stays ON forever (IPM can enter sleep mode).
When vehicle speed is under 10 kph, with ignition key not inserted and lgate open switch is OPEN, Tailgate Open
warning stays ON for 20 min and then is turned OFF.
Chime Control
1.The chime warns the driver that a problem is occurred.
These warning are:
a. Seat belt
b. Parking on
c. Over speed
d. Key reminder
e. Light Warning
f. Doors Open
g. Tailgate open warning
2. Chime sound priority:
a. 1st : Seatbelt warning
b. 2nd : Overspeed warning
c. 3rd : Door open warning
d. 4th : T/Gate open warning
e. 5th : Key operated warning
f. 6th : Parking Brake warning
g.7th : Light ON warning
h. 8th : Key learning sound
3. If two different warning condition happen at the same time, chime should work only for the highest warning
condition.
4. Cluster indicators should work for two warning behavior.
