DESCRIPTION AND OPERATION
IGNITION SWITCH
In the RUN position, the ignition switch connects
circuit A1 from the Power Distribution Center (PDC)
to circuit A21. A 30 amp fuse in the PDC protects cir-
cuits A1 and A21. Circuit A21 feeds a bus bar in the
fuse block. The bus bar feeds circuits G5, F12, and
F15.
²Circuit G5 powers the gauge cluster warning
lamps and the daytime running lamp (DRL) module.
Fuse cavity 11 (5 amp) in the fuse block protects cir-
cuit G5.
²Circuit F12 splices to the Powertrain Control
Module (PCM), duty cycle purge solenoid, EGR sole-
noid, ABS system, and a bus bar in the PDC. The
bus bar in the PDC feeds the coil side of the radiator
fan relay, A/C compressor clutch relay, and the fuel
pump relay. A 15 amp fuse in the fuse block, cavity
10, protects circuit F12.
²Circuit F15 feeds the Airbag Control Module
(ACM). A 10 amp fuse in the fuse block, cavity 9, pro-
tects circuit F15.
BATTERY FEED
Circuit A14 from the Power Distribution Center
(PDC) supplies battery voltage to cavity 46 of the
Powertrain Control Module (PCM). A 20 amp fuse in
the PDC protects circuit A14.
HELPFUL INFORMATION
Circuit A14 connects to a bus bar in the PDC that
the battery feeds. Circuit A14 powers the AutomaticShut Down (ASD) relay and fuel pump relay. The
A14 circuit also splices to the data link connector.
POWER (DEVICE) GROUND
Circuit Z12 connects to cavities 10 and 50 of the
Powertrain Control Module (PCM). The Z12 circuit
provides ground for PCM internal drivers that oper-
ate high current devices like the injectors and igni-
tion coils.
Internal to the PCM, the power (device) ground cir-
cuit connects to the PCM sensor return circuit (from
circuit K4) and the signal ground circuit (Z11).
HELPFUL INFORMATION
Circuit Z12 which supplies ground for the PCM
high current drivers, has the same termination point
as circuit Z11. The termination point is the left side
of the radiator closure panel.
If the system loses ground for the ganged circuits,
at the left side of the radiator closure panel, the vehi-
cle will not operate. Check the connection at the
ganged ground circuit eyelet.
SIGNAL GROUND
The signal ground circuit Z11 connects to cavity 47
of the PCM. The Z11 circuit provides ground for the
sensors that provide inputs to the PCM. Internal to
the PCM, the signal ground circuit connects to the
PCM sensor return circuit (from circuit K4) and the
power (device) ground circuit (Z12).
The termination point for circuit Z11 is an eyelet
attached to the left side of the radiator closure panel.

Circuit Z12 which supplies ground for the PCM
high current drivers, has the same termination point
as circuit Z11. The termination point is the left side
of the radiator closure panel.
If the system loses ground for the ganged circuits,
at the left side of the radiator closure panel, the vehi-
cle will not operate. Check the connection at the
ganged ground circuit eyelet.
DATA LINK CONNECTOR
Circuit A14 supplies battery voltage to the univer-
sal data link connector. Circuit A14 originates in the
Power Distribution Center (PDC) and connects to a
battery fed bus bar. A 20 amp fuse protects circuit
A14.
A twisted pair of wires, circuits D1 and D2, from
the Airbag Control Module (ACM) connect to the uni-
versal data link connector.
Ground circuit Z12 splices to two cavities of the
data link connector. The Z12 circuit also connects to
cavities 10 and 50 of the PCM connector.
Circuit D20 connects to cavity 75 of the PCM and
to the universal data link connector. Circuit D20 is
the SCI receive circuit for the PCM.
Circuit D21 connects to cavity 65 of the PCM and
to the universal data link connector. Circuit D21 is
the SCI transmit circuit for the PCM. The D21 cir-
cuit splices to the ABS module.
HELPFUL INFORMATION
The grounding point for circuit Z12 is the left side
of the radiator closure panel.
Circuit Z12 also supplies ground for the PCM high
current drivers and has the same termination point
as circuit Z11.
If the system loses ground for the ganged circuits
at the left side radiator closure panel the vehicle will
not operate. Check the connection at the ganged
ground circuit eyelet.
AUTOMATIC SHUT DOWN RELAY
The Automatic Shut Down (ASD) relay is located
in the Power Distribution Center (PDC). Power for
the coil and contact side of the relay is supplied on
circuit A14. This circuit is HOT at all times and pro-
tected by a 20 amp fuse located in the PDC.
The Powertrain Control Module (PCM) controls the
ground path for the coil side of the relay on circuit
K51. This circuit connects to cavity 67 of the PCM.
When the PCM supplies the ground path on circuit
K51 the contacts in the relay CLOSE connecting cir-
cuits A14 and A142. The A142 circuit is spliced and
supplies power to the generator, fuel injectors, PCM,
ignition coil, and heated oxygen sensors.
HELPFUL INFORMATION
²Refer to group 14 Fuel System, for additional
information.
²Check the 20 amp fuse located in the PDC.
FUEL PUMP MOTOR
Circuit A14 is a bus bar in the Power Distribution
Center (PDC) and connects to battery voltage. The
contact side of the fuel pump relay connects circuit
A14 and circuit A141. A 20 amp fuse in the PDC pro-
tects circuits A14 and A142.
Circuit A141 supplies voltage for the fuel pump
motor. Circuit Z1 provides ground for the fuel pump
motor. The grounding point for circuit Z1 is the right
rear wheel house.
Circuit F12 supplies voltage to the coil side of the
fuel pump relay. The Powertrain Control Module
(PCM) controls the ground path circuit for the coil
side of the fuel pump relay on circuit K31. Circuit
K31 connects to cavity 74 of the PCM.
HELPFUL INFORMATION
Circuit F12 originates in the fuse block where it
connects to a bus bar fed by circuit A21. In the
START and RUN position, the ignition switch con-
nects circuit A1 from the PDC to circuit A21. A 30
amp fuse in the PDC protects circuits A1 and A21.
Circuit F12 splices to feed the ABS control module,
EGR solenoid, Torque Converter Clutch (TCC) sole-
noid, leak detection pump, and the EVAP/Purge sole-
noid.
Circuit F12 also connects to a bus bar in the PDC.
The bus bar supplies voltage to the coil side of radi-
ator fan relay and A/C clutch relay, as well as the
fuel pump relay.
VEHICLE SPEED SENSOR
Circuit K7 supplies 8 volts from the Powertrain
Control Module (PCM) to the Vehicle Speed Sensor
(VSS). The K7 circuit connects to cavity 44 of the
PCM connector.
Circuit G7 from the VSS provides an input signal
to the PCM. The G7 circuit connects to cavity 66 of
the PCM connector.
The PCM provides ground for the VSS signal (cir-
cuit G7) through circuit K4. Circuit K4 connects to
cavity 43 of the PCM connector.
HELPFUL INFORMATION
Circuit G7 splices to the speedometer and odome-
ter in the instrument cluster.
Circuit K7 splices to supply 8 volts to the camshaft
position sensor and crankshaft position sensor.
Circuit K4 splices to supply ground for the signals
