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.

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.

DESCRIPTION AND OPERATION
INSTRUMENT CLUSTER
The Instrument Cluster, located on the right side
of the instrument panel, provides the operator with
gauges and warning lamps relating to vehicle opera-
tion. All gauges in the standard and optional cluster
are magnetic type and logic driven.
Battery voltage for the clusters warning lamps and
gauges is provided on the G5 circuit. This circuit con-
nects from the fuse block and is protected bya5amp
fuse located in cavity 11. The cluster is powered only
when the ignition switch is in the START or RUN
position. The cluster is also powered on initial driv-
er's door opening.
Illumination lamps, internal to the cluster, receive
battery voltage on the E2 circuit from the 4 amp fuse
located in cavity 12 of the fuse block. This circuit is
HOT only when the headlamp switch is in the ON
position. Grounding for the cluster is provided on the
Z3 circuit and terminates at the instrument panel
left center support.
The M1 circuit also feeds the cluster through a 10
amp fuse in the Power Distribution Center (PDC).
This fuse is HOT at all times and also used to power
the underhood lamp, and the interior lamps. The
fuse is also lifted OPEN during vehicle shipping to
reduce battery draw.
SPEEDOMETER
The speedometer and odometer receive their infor-
mation on the G7 circuit from the Vehicle Speed Sen-
sor (VSS) on manual and 3±spd automatic
transmission applications. The G7 circuit also pro-
vides a signal to the Powertrain Control Module
(PCM).Logic internal to the instrument cluster adjusts the
position of the gauge pointer to the correct vehicle
speed using the signal on the G7 circuit.
TACHOMETER
The tachometer is connected to the Powertrain
Control Module (PCM) on the G21 circuit. It uses
solid state circuity to decode the ignition pulses
received from the PCM to adjust the gauge pointer to
the proper position.
ENGINE COOLANT TEMPERATURE GAUGE
The temperature gauge is connected to the engine
coolant temperature sensor on the G20 circuit. The
engine coolant temperature sensor for the gauge is a
combination unit. One side of the unit is used for the
Powertrain Control Module (PCM) and the other side
for the cluster. The sending unit is case grounded to
the engine.
The logic driven gauge moves in response to the
measured resistance of the engine coolant tempera-
ture sending unit.
FUEL GAUGE
The fuel level gauge is connected to the fuel pump
module on the G4 circuit. The fuel pump module con-
tains the fuel pump and a variable resistor for the
gauge. Grounding for the fuel pump module is pro-
vided on the Z2 circuit and terminates at the left
rear wheel house.
The logic driven gauge moves in response to the
measured resistance of the fuel tank sending unit.
The fuel level sensor contains a variable resistor.
As the position of the float arm on the level sensor
changes, the resistor changes the current flow
through the fuel gauge circuit. A change in current
flow alters the magnetic field in the fuel gauge which
changes the pointer position.

PLR04302978W-1

Downloaded from www.Manualslib.com manuals search engine 8W-43 AIRBAG SYSTEM
DESCRIPTION AND OPERATION
AIRBAG CONTROL MODULE (ACM)
Two different circuits supply battery voltage from
the fuse block to the Airbag Control Module (ACM),
F15 and F25. The F15 and F25 circuits are connected
to separate bus bars internal to the fuse block. Dif-
ferent circuits from the Power Distribution Center
(PDC) and ignition switch supply battery voltage to
the fuse block bus bars.
The F25 circuit supplies battery voltage to the
ACM only when the ignition switch is in the RUN
position. The F15 circuit powers the ACM when the
ignition switch is in either the START or RUN posi-
tion.
An internal bus bar in the ignition switch connects
the A1 circuit from the PDC to the A21 circuit when
the switch is either the START or RUN position. The
A21 circuit supplies battery voltage to the bus bar in
the fuse block that feeds the F15 circuit. A 30 amp
fuse in the PDC protects the A1 and A21 circuits. A
10 amp fuse in the fuse block, cavity 9, protects the
F15 circuit.
When the ignition switch is in the RUN position, it
connects the A2 circuit from the PDC to the A22 cir-
cuit. The A22 circuit supplies battery voltage to the
fuse block bus bar that feeds the F25 circuit. A 40
amp fuse in the PDC protects the A2 and A22 cir-
cuits. A 10 amp fuse in the fuse block, cavity 5, pro-
tects the F25 circuit.
Circuits D1 and D2 are connected to the CCD Bus
and the ACM. The CCD bus is used to provide com-
munications between modules and the universal data
link connector.
The ACM has a case ground and an external dedi-
cated ground, circuit Z6. The dedicated ground con-
nects to the instrument panel right center support.
AIRBAG IMPACT SENSOR
The Airbag system uses a sensor internal to the
Airbag Control Module (ACM) to detect impact. For
information regarding operation of this sensor, refer
to the appropriate group of the Service Manual.
AIRBAG SQUIB (AIRBAG IGNITER)
DRIVERS SIDE AIRBAG
Two circuits, R43 and R45, connect the ACM to the
drivers side airbag module squib (igniter) after pass-
ing through the clock spring connector. Circuit R43
from cavity 3 of the ACM 4-way connector connects
to the squib. Circuit R45 from cavity 4 of the ACM
4-way connector connects to the squib. R43 and R45
are a twisted pair of wires.
PASSENGERS SIDE AIRBAG
Two circuits, R42 and R44, connect the ACM to the
passengers side airbag module squib (igniter). Circuit
R42 from cavity 1 of the ACM 4-way connector con-
nects to the squib. Circuit R44 from cavity 2 of the
ACM 4- way connector connects to the squib. R42
and R44 are a twisted pair of wires.
Circuits R50 and R51 are connected from the ACM
to the passangers airbag. These circuits are used to
monitor the pressure switch.
AIRBAG WARNING LAMP
The Airbag Warning lamp is used to alert the oper-
ator of a problem with the Airbag system. The lamp
is illuminated when the Airbag Control Module
(ACM) grounds the R41 circuit. Refer to the appro-
priate section of the Service Manual or Diagnostic
Test Procedures Manual to diagnosis this system.
HELPFUL INFORMATION
²Check for blown fuses in the circuit that connect
to the ignition switch and those that connect to the
ACM.
²While the bus bars in the fuse block power the
ACM, they also feed additional components on sepa-
rate fuse protected circuits.
²The ACM has a case ground and an external
dedicated ground. The dedicated ground connects to
the instrument panel right center support.
