DESCRIPTION AND OPERATION (Continued)
HELPFUL INFORMATION
• Refer to group 14 of the Service Manual or the
appropriate Diagnostic Test Procedures Manual for
additional information.
POWER STEERING PRESSURE SWITCH
The power steering pressure switch opens and
closes circuit K10 between the Powertrain Control
Module (PCM) and ground. Circuit K10 connects to
cavity 45 of the PCM connector.
Circuit Z1 provides a ground for the power steering
pressure switch. The ground is terminated at the
Body Control Module (BCM).
DUTY CYCLE EVAP/PURGE SOLENOID
Circuit F18 supplies battery voltage to the duty
cycle EVAP/Purge solenoid. This circuit is HOT in
the START and RUN position only. It is also spliced
and provides power for the Anti-Lock warning lamp,
A/C clutch relay, and high speed radiator fan relay.
Circuit F18 connects to the PDC, cavity 9, and is
protected by a 10 amp fuse. Power for the fuse is
supplied on circuit A21 from the ignition switch. Cir-
cuit A1 provides power for the A21 circuit and is pro-
tected by a 20 amp fuse located in cavity 8 of the
Power Distribution Center (PDC).
The Powertrain Control Module (PCM) controls the
ground path for the solenoid on circuit K52. Circuit
K52 connects to cavity 68 of the PCM connector.
HELPFUL INFORMATION
• Refer to group 14 and group 25, for system oper-
ation
• Check the 10 amp fuse located in cavity 9 of the
PDC.
• Check the 20 amp fuse located in cavity 8 of the
PDC
ELECTRONIC EGR TRANSDUCER (EET) SOLENOID
Circuit A142 supplies voltage to the EET solenoid.
The Powertrain Control Module (PCM) controls the
ground path for the solenoid on circuit K35 and con-
nects to cavity 40 of the PCM connector.
Circuit A142 is spliced and connects with the fuel
injectors, generator, and the Automatic Shut-Down
(ASD) relay. This circuit is HOT when the ASD relay
is energized.
HELPFUL INFORMATION
• Refer to Group 14, for system operation.
VAPOR CANISTER LEAK DETECTOR
Power for the vapor canister leak detector is pro-
vided on circuit F18. This circuit is protected by a 10
amp fuse located in cavity 9 of the junction block.
Power for the fuse is supplied on circuit A21 from the
8W - 30 FUEL/IGNITION SYSTEM
ignition switch. Circuit A21 is HOT in the START
and RUN positions only.
The Powertrain Control Module (PCM) controls the
ground path for the leak detection pump solenoid and
leak detection pump switch.
Circuit K106 is connected to cavity 77 of the PCM
connector and to the leak detection solenoid.
Circuit K107 is connected to cavity 72 of the PCM
connector and to the leak detection pump switch.
HELPFUL INFORMATION
• Check the 10 amp fuse located in cavity 9 of the
junction block.
• Refer to the appropriate section of the service
manual, or the diagnostic test procedures manual.
PARK/NEUTRAL SWITCH INPUT
When CLOSED the Transmission Range Switch
(TRS) provides an input to the Powertrain Control
Module (PCM) on circuit T41. This circuit connects to
cavity 76 of the PCM connector. The T41 circuit is
spliced and provides a ground path for the engine
starter relay, and the Transmission Control Module
(TCM).
CCD BUS
The CCD Bus is used to allow the Powertrain Con-
trol Module (PCM) and other modules to communi-
cate with each other and the universal data link
connector.
Circuit D1 is used for CCD (+) and connects to cav-
ity 59 of the PCM connector. Circuit D2 is used for
CCD (-) and connects to cavity 60 of the PCM con-
nector.
