DESCRIPTION AND OPERATION (Continued)
• Circuit K39 connects to cavity 57 of the PCM
connector.
• Circuit K40 connects to cavity 48 of the PCM
connector.
• Circuit K59 connects to cavity 58 of the PCM
connector.
• Circuit K60 connects to cavity 49 of the PCM
connector.
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 Z12 provides ground for the power steering
pressure switch. The grounding point for circuit Z12
is the left side of the radiator closure panel.
TORQUE CONVERTER CLUTCH SOLENOID (TCC)
The Powertrain Control Module (PCM) operates
the TCC solenoid by providing a ground path on cir-
cuit K54. Circuit K54 connects to PCM cavity 79.
Circuit F12 supplies battery voltage to the TCC
solenoid. Circuit F12 connects to a bus bar in the
fuse block fed by circuit A21. A 15 amp fuse in the
fuse block, cavity 10, protects circuit F12. Circuit F12
connects to cavity 20 of the PCM connector.
HELPFUL INFORMATION
Circuit F12 splices to feed the ABS control module,
PCM, EGR solenoid, leak detection pump, and the
duty cycle EVAP/Purge solenoid. The F12 circuit also
connects to a bus bar in the PDC that supplies volt-
age to the coil side of radiator fan relay, A/C clutch
relay, and fuel pump relay.
In the RUN or START position, the ignition switch
connects circuit A1 from the fuse block and circuit
A21. Circuit A1 connects to battery voltage and is
protected by a 30 amp fuse in the PDC.
DUTY CYCLE EVAP/PURGE SOLENOID
Circuit F12 supplies battery voltage to the Duty
Cycle EVAP/Purge solenoid. The Powertrain Control
Module (PCM) switches ground path for the solenoid
ON and OFF through circuit K52.
Circuit F12 connects to a bus bar in the fuse block
fed by circuit A21. A 15 amp fuse in the fuse block,
cavity 10, protects circuit F12. Circuit F12 also con-
nects to cavity 20 of the PCM connector.
Circuit K52 connects to cavity 68 of the PCM, and
cavity 1 of the solenoid connector.
HELPFUL INFORMATION
Circuit F12 splices to feed the ABS control module,
PCM, EET solenoid, leak detection pump, and the
TCC solenoid. The F12 circuit also connects to a bus
bar in the PDC that supplies voltage to the coil side
of radiator fan relays, A/C clutch relay, and fuel
pump relay.
8W - 30 FUEL/IGNITION SYSTEMS
In the START or RUN position, the ignition switch
connects circuit A1 from the fuse block and circuit
A21. Circuit A1 connects to battery voltage and is
protected by a 30 amp fuse in the PDC.
