DESCRIPTION AND OPERATION
ANTI-LOCK BRAKES
Power for the Anti-Lock brake system is supplied
by two fuses. There is a 15 amp fuse located in the
fuse block cavity 10. This fuse supplies power to the
Controller Anti Lock Brake (CAB), and the ABS sys-
tem relay on the F12 circuit. The F12 circuit also
supplies power to the Powertrain Control Module
(PCM). Power for the fuse is supplied on the A21 cir-
cuit from the ignition switch. This fuse is HOT in the
START/RUN position.
The second fuse is located in the Power Distribu-
tion Center (PDC). It is a 40 amp fuse. This fuse is
HOT at all times and supplies power to the contact
side of the ABS pump motor relay.
There are three grounding points used in the ABS
system. One is a case ground on the CAB. The sec-
ond is the Z12 circuit at the CAB connector cavity 5.
This ground is spliced, and terminates at the left side
of the radiator closure panel.
The third ground is on the Z1 circuit. This ground
is used for the ABS hydraulic modulator, ABS system
relay, and the ABS pump motor. This ground, like the
Z12 ground splices and terminates at the left head-
lamp ground.
Additional information on the circuit function of
the ABS system is listed below. For diagnostic and
testing procedures, refer to the appropriate section of
the Service Manual or the Diagnostic Test Proce-
dures Manual.
ABS WARNING LAMP
The ABS warning lamp is an output from the Con-
troller Anti Lock Brake (CAB) and the ABS relay
box. It is used to alert the operator of a problem in
the ABS system. The G19 circuit from the CAB and
the ABS system relay is used to detect a problem. If
a problem is detected, the CAB grounds the G19 cir-
cuit and illuminates the lamp in the instrument clus-
ter.
Circuit G19 is also an output of the CAB to the
ABS system relay contact side.
ABS SYSTEM RELAY
The system relay is used for the operation of the
ABS system. Power for the relay is supplied on the
B57 circuit from cavity 57 of the Controller Anti Lock
Brake (CAB).
Ground for the relay is on the Z1 circuit. This
ground is spliced in with the pump motor and termi-
nates at the left headlamp ground.
When the system is operating normally power for
the contact side of the relay is supplied from the
CAB on the B57 circuit. It passes through the relay
to the Z1 ground and terminates at the left headlamp
ground. If a problem is detected in the system, the
contact side of the relay switches from the Z1 to the
F12 circuit. This causes the ABS warning lamp in
the instrument cluster to illuminate.
ABS PUMP MOTOR RELAY
The ABS pump motor relay controls when the
pump motor runs. Power for the coil side of the relay
is supplied from cavity 47 of the Controller Anti Lock
Brake (CAB) on the B47 circuit. This circuit also sup-
plies voltage for the contact side of the system relay.
The ground side of the coil is controlled by the B116
circuit. Circuit B116 connects to cavity 16 of the CAB
connector.
Circuit B120 from cavity 20 of the CAB connector
powers the ABS pump motor. This circuit is also used
as an input to the CAB for pump motor monitoring.
HYDRAULIC MODULATOR
The hydraulic modulator is used for the controlling
of the brake system pressure to the wheels. The mod-
ulator is made up of four solenoids.
Circuits involved are, B142 for the left front wheel,
B143 for the right front wheel, B146 for the left rear
wheel, and B148 for the right rear wheel.
The solenoids use a common ground on the Z1 cir-
cuit. There are two Z1 circuits from the modulator.
Both of these grounds terminate at the left headlamp
ground, and are spliced in with the ABS pump motor
and the ABS system relay.
8W - 35 - 6 8W - 35 ANTI-LOCK BRAKESPL
Downloaded from www.Manualslib.com manuals search engine WHEEL SPEED SENSORS
There are four wheel speed sensors, one at each
wheel. The sensors use a tone wheel to determine
wheel speed. Input to the Controller Anti Lock Brake
(CAB) is done on the following circuits. All of these
circuits are a twisted pair.
B8 and B9 for the left front wheel (cavity 8 and
cavity 9).
B6 and B7 for the right front wheel (cavity 6 and
cavity 7).
B3 and B4 for the left rear wheel (cavity 3 and cav-
ity 4).
B1 and B2 for the right rear wheel (cavity 1 and
cavity 2).
BRAKE SWITCH INPUT
Circuit L50 is an input to the Controller Anti Lock
Brake (CAB). The L50 connects to cavity 13 of the
CAB connector. Circuit L50 is spliced in with the
stop lamps and is used to provide the CAB with
information on when the brakes are being applied.
DATA LINK CONNECTOR
Circuit D21 is used for diagnostics of a fault with
the ABS system. It is spliced in with the Powertrain
Control Module (PCM) circuits and used as an output
from the Controller Anti Lock Brake (CAB). Circuit
D21 connects to cavity 51 of the CAB connector.
HELPFUL INFORMATION
²Check the 15 amp fuse located in cavity 10 of
the fuse block.
²Check the 40 amp fuse located in the PDC.
²Check for a good ground at the left headlamp
ground.
²Check the case ground on the CAB
²Refer to the appropriate section of the service
manual, or the Diagnostic Test Procedures Manual.

Downloaded from www.Manualslib.com manuals search engine There are two switches used in this system and
they are wired in parallel form. A parking brake
switch located on the parking brake mechanism will
illuminate the lamp if the normally OPEN switch is
CLOSED. This switch is case grounded.
The other switch used is the brake warning lamp
switch. This switch is normally OPEN. When the
brake system pressure is below a predetermined level
the switch CLOSES and completes a path to ground
from the G9 circuit at the cluster, through the
switch, to the left headlamp ground.
ANTI-LOCK WARNING LAMP
The Anti-Lock warning lamp is used to alert the
driver of a problem in the ABS system. When the
ABS controller determines a problem in the system it
grounds the G19 circuit and illuminates the lamp.
HELPFUL INFORMATION
²Check the 5 amp fuse in cavity 11 of the fuse
block.
²Check the 4 amp fuse in cavity 12 of the fuse
block.
²Check the Ignition-Off Draw fuse in the PDC.
²Check for a good ground at the instrument panel
left center support.
²For additional diagnostic tests refer to the
appropriate section of the Service Manual.
