Solenoid SUZUKI SWIFT 2000 1.G RG413 Service Workshop Manual

0A-16 GENERAL INFORMATION
SHORT CIRCUIT CHECK (WIRE HARNESS TO
GROUND)
1) Disconnect negative (–) cable at battery.
2) Disconnect connectors at both ends of the circuit to be
checked.
3) Measure resistance between terminal at one end of circuit
(A-1 terminal in the figure) and body ground. If continuity is
indicated, it means that there is a short to ground between
terminals A-1 and C-1 of the circuit.
4) Disconnect the connector included in circuit (connector B)
and measure resistance between A-1 and body ground.
If continuity is indicated, it means that the circuit is shorted to
the ground between terminals A-1 and B-1.
INTERMITTENT AND POOR CONNECTION
Most intermittent are caused by faulty electrical connections or
wiring, although a sticking relay or solenoid can occasionally be
at fault. When checking it for proper connection, perform careful
check of suspect circuits for :
Poor mating of connector halves, or terminals not fully
seated in the connector body (backed out).
Dirt or corrosion on the terminals. The terminals must be
clean and free of any foreign material which could impede
proper terminal contact. However, cleaning the terminal with
a sand paper or the like is prohibited.
Damaged connector body, exposing the terminals to mois-
ture and dirt, as well as not maintaining proper terminal ori-
entation with the component or mating connector. NOTE:
If the circuit to be checked is connected to other parts
(1), disconnect all connectors of those parts.
Otherwise, diagnosis will be misled.

GENERAL DESCRIPTION
COMPONENTS/PARTS LOCATION AND BRAKE HOSE/PIPE ROUTING
The ABS (Antilock Brake System) controls the fluid pressure applied to the Wheel cylinder of each brake from
the master cylinder so that each wheel is not locked even when hard braking is applied.
This ABS has also the following function.
While braking is applied, but before ABS control becomes effective, braking force is distributed between the front
and rear so as to prevent the rear wheels from being locked too early for better stability of the vehicle.

ANTILOCK BRAKE SYSTEM (ABS) 5E-3
The main component parts of this ABS include the following parts in addition to those of the conventional brake
system.
Wheel speed sensor which senses revolution speed of each wheel and outputs its signal.
ABS warning lamp which lights to inform abnormality when system fails to operate properly.
ABS hydraulic unit/control module assembly is incorporated ABS control module, ABS hydraulic unit (actua-
tor assembly), fail-safe relay and pump motor relay.
–ABS control module which sends operation signal to ABS hydraulic unit to control fluid pressure applied to
each wheel cylinder based on signal from each wheel speed sensor so as to prevent wheel from locking.
–ABS hydraulic unit which operates according to signal from ABS control module to control fluid pressure
applied to wheel cylinder of each 4 wheels.
–Fail-safe relay (solenoid valve) relay which supplies power to solenoid valve in ABS hydraulic unit and
pump motor relay.
–Pump motor relay which supplies power to pump motor in ABS hydraulic unit.
G sensor which detects body deceleration speed. (For 4WD model only)]
This ABS is equipped with Electronic Brake force Distribution (EBD) system that controls a fluid pressure of rear
wheels to best condition, which is the same function as that of proportioning valve, by the signal from wheel sen-
sor independently of change of load due to load capacity and so on. And if the EBD system fails to operate prop-
erly, the brake warning lamp lights to inform abnormality.

DTC C1063 (DTC 63) – ABS FAIL-SAFE RELAY CIRCUIT
DESCRIPTION
ABS control module monitors the voltage at the terminal of solenoid circuit constantly with ignition switch turned
ON. Also, immediately after ignition switch is turned ON, perform initial check as follows.
Switch fail-safe relay in the order of OFF → ON and check if voltage changes to Low → High. If anything faulty
is found in the initial check and when the voltage is low with ignition switch turned ON, this DTC will be set.
INSPECTION
1. Ignition switch 3. ABS hydraulic unit/control module connector 5. To pump motor relay
2. ABS hydraulic unit/control module assembly 4. To solenoid valves 6. Fail-safe relay
Step Action Yes No
1 Check battery voltage. Is it about 11 V or
higher?Go to Step 2. Check charging system
referring to “CHARGING
SYSTEM” section.
2 Check ABS main fuse and connection.
Is it in good condition?Go to Step 3. Repair and/or replace
fuse.
3 1) Ignition switch OFF.
2) Disconnect ABS hydraulic unit/control mod-
ule connector.
3) Check proper connection to ABS hydraulic
unit/control module at terminal “E19-25”.
4) If OK, then measure voltage between con-
nector terminal “E19-25” and body ground.
Is it 10 – 14 V?Substitute a known-good
ABS hydraulic unit/con-
trol module assembly and
recheck.“WHT/BLU” circuit open
or short to ground.

7) With diagnosis switch terminal (1) of monitor coupler (2) con-
nected to ground terminal (3) using service wire (4), turn
ignition switch ON and check if ABS warning lamp indicates
DTC 12.
If malfunction DTC is indicated, repair it first.
8) Turn ignition switch OFF.
9) Perform the following checks with help of another person.
Brake pedal (1) should be depressed and then ignition
switch (2) turned ON by one person and wheel (3) should be
turned by another person’s hand. At this time, check that :
Operation sound of solenoid is heard and wheel turns only
about 0.5 sec. (Brake force is depressurized).
Operation sound of pump motor is heard and pulsation is felt
at brake pedal.
10) If all 4-wheels cannot be checked during one ignition cycle
(OFF → ON), repeat Steps 8) and 9) till all 4 wheels are
checked.
If a faulty condition is found in Steps 9) and 10), replace
hydraulic unit/control module assembly.
11) Turn ignition switch OFF and remove service wire from mon-
itor coupler.
