5A-20 BRAKE CONTROL SYSTEM

Electronic Brake-force Distribution (EBD) System

ABS has the EBD function. EBD is a function which
controls braking force distribution of a front wheel and a
rear wheel, and makes brake fluid pressure of a rear
wheel the optimal. If the rate of a slip of a rear wheel
becomes large more than fixed compared with a front
wheel about the rate of a slip in order to perform
braking force distribution of a front wheel and a rear
wheel, the brake fluid pressure of a rear wheel will be
controlled. EBD enables it to always utilize the braking
power of a rear wheel for the maximum according to
the load change concerning the back axis by vehicles
loading states (No luggage, loading, etc.), deceleration,
etc. Brake fluid pressure control to a rear wheel is
performed by the EBD function which used the ABS
function without the mechanical proportioning valve.
C05L300016
Brake Pedal Travel
Vehicles equipped with the Anti-lock Brake System may
be stopped by applying normal force to the brake pedal.
Although there is no need to push the pedal beyond the
point where it stops or holds the vehicle, by applying
more force the pedal will continue to travel toward the
floor.
This extra brake pedal travel is normal.

General Diagnosis
General Information
ABS troubles can be classified into two types, those
which can be detected by the ABS warning lamp and
those which can be detected as a vehicle abnormality
by the driver.
In either case, locate the fault in accordance with the
“BASIC DIAGNOSTIC FLOWCHART” and repair.
Please refer to Section 5C for the diagnosis of
mechanical troubles such as brake noise, brake judder
(brake pedal or vehicle vibration felt when braking),
uneven braking, and parking brake trouble.

NOTES FOR WORKING ON ELECTRICAL ITEMS
Battery

BATTERY CABLE
Disconnecting the Battery Cable
1. All switches should be "OFF" position.
2. Disconnect the battery ground cable.
3. Disconnect the battery positive cable.
CAUTION:
It is important that the battery ground cable be
disconnected first.
Disconnecting the battery positive cable first can result in
a short circuit.














Connecting the Battery Cable
Follow the disconnecting procedure in the reverse order to
connect the battery cables.
CAUTION:
Clean the battery terminal and apply light coat of grease to
prevent terminal corrosion.




CONNECTOR HANDLING
Disconnecting the Connectors
Some connectors have a tang lock to hold the connectors
together during vehicle operation.
Some tang locks are released by pulling them towards you
1.
Other tang locks are released by pressing them forward
2.
Determine which type of tang lock is on the connector being
handled.



Firmly grasp both sides (male and female) of the connector.
Release the tang lock and carefully pull the two halves of the
connector apart.
Never pull on the wires to separate the connectors.
This will result in wire breakage.

ELECTRICAL-BODY AND CHASSIS 8A-7


Pin Tang Lock Type
1. Insert a slender shaft 3 into the connector housing open
end
4.
2. Push the tang lock
8flat (toward the wire side of the
connector).
Pull the wire
6 with pin 7free from the wire side of the
connector.



Connector Pin Insertion
1. Check that the tang lock 8 is fully up.
2. Insert the pin
7 from the connector wire side 9.
Push the pin in until the tang lock closes firmly.
3. Gently pull on the wires
6to make sure that connector pin
is firmly set in place.



Fuse Replacement
The replacement fuse must have the same amperage
specification as the original fuse.
Never replace a burn out fuse with a fuse of a different
amperage specification.
Doing so can result in an electrical fire or other serious circuit
damage.



Parts Handling
Be careful for parts handling and any part should not be
dropped or thrown, otherwise short circuit or disorder may
result.



Wiring Harness
1. When assembling the parts, be careful not to bite or wedge
the wiring harness.
2. All electrical connections must be kept clean and tight.

Caution:
Never push or tow the vehicle in an attempt to start it.
Extensive damage to the emission system and other
vehicle parts will result.
(Only catalytic converter vehicle)
Treat both the discharged battery and the booster battery
with great care when using jumper cables.
Carefully follow the procedure outlined below.
Always be aware of the dangers of sparking.
Failure to follow the following procedure can result in:
a. Serious personal injury, specially to your eyes.
b. Extensive property damage from a battery explosion,
battery acid discharge, or electrical file.
c. Extensive damage to the electronic components o
f
both vehicles.
Do not use a 24 volt booster battery.
Serious damage to the vehicle's electrical system and
electronic components will result.

Jump Starting Procedure
1. Set the parking brake on both vehicles.
2. If one or both vehicles is equipped with a manual
transmission, place the gear shift in the "NEUTRAL"
position.
3. Turn off the ignition on both vehicles.
4. Turn off all vehicle lights and accessories.
5 Be sure that the two vehicles are not touching.

Attach the end of one jumper cable to the booster battery
positive terminal.
6
Attach the other end of the same cable to the discharged
battery positive terminal.
7. Once again, check that the booster battery has a 12 vol
t
rating.
8.
Attach one end of the remaining booster cable to the
booster battery negative terminal.
9.
Attach the other end of the booster cable to a solid ground
(such as the air conditioner compressor mounting bracke
t
or the alternator mounting bracket) in the engine room o
f
the vehicle with the discharged battery.
Be sure that the ground connection is at least 500 mm (20
in) from the discharged battery.
