DESCRIPTION AND OPERATION
STARTING SYSTEM (MANUAL TRANSAXLE)
The Power Distribution Center (PDC) supplies bat-
tery voltage to the engine starter motor solenoid
through circuit T40 when the coil side of the engine
starter motor relay energizes. Circuit A1 contains a
20 amp fuse, and feeds the contact side of the engine
starter motor relay. Both the 20 amp fuse and the
engine starter motor relay are located in the PDC.
The ignition switch supplies battery voltage to the
coil side of the engine starter motor relay on circuit
A41 when the key is moved to the START position
and the operator has pressed the clutch pedal to
CLOSE the clutch pedal position switch. Circuit Z1 is
the ground for the coil side of the engine starter
motor relay. When the coil side of the relay energizes,
the contacts CLOSE, supplying battery voltage to the
engine starter motor solenoid.
Circuit A0 (battery positive cable) supplies battery
voltage to the engine starter motor when the solenoid
energizes. Ground for the engine starter motor is
supplied through the starter motor case.
HELPFUL INFORMATION
• Check for blown engine starter motor fuse in
cavity 8 of the PDC
• Move the ignition key to the START position
and with the clutch pedal pressed, listen for the
starter motor relay to click. The engine starter motor
relay is located in the PDC
• Check for a good ground at the starter motor
STARTING SYSTEM (AUTOMATIC TRANSAXLE)
The Power Distribution Center (PDC) supplies bat-
tery voltage to the engine starter motor solenoid
8W - 21 STARTING SYSTEM
8W-21 STARTING SYSTEM
through circuit T40 when the coil side of the engine
starter motor relay energizes. Circuit A1 contains a
20 amp fuse, and feeds the contact side of the engine
starter motor relay. Both the 20 amp fuse and the
engine starter motor relay are located in the PDC.
The ignition switch supplies battery voltage to the
coil side of the engine starter motor relay on circuit
A41 when the key is moved to the START position
and the PARK/NEUTRALportion of the Transmission
Range Sensor (TRS) is CLOSED. Circuit A41 also
provides an ignition start input to the Transmission
Control Module (TCM).
Ground for the coil side of the engine starter motor
relay is supplied on the T41 circuit by the TRS,
which is case-grounded. The T41 circuit is also an
input to the Powertrain Control Module (PCM), cav-
ity 76, and the TCM, cavity 41. This input is used to
indicate when the vehicle is in the PARK or NEU-
TRAL positions.
Circuit A0 (battery positive cable) supplies battery
voltage to the engine starter motor when the solenoid
energizes. Ground for the engine starter motor is
supplied through the starter motor case.
HELPFUL INFORMATION
• Check for blown engine starter motor fuse in
cavity 8 of the PDC
• With the gear selector in the PARK or NEU-
TRAL position, move the ignition key to the START
position and listen for the starter motor relay to
click. The engine starter motor relay is located in the
PDC
• Check for a good ground at the starter motor
• The TRS is case-grounded and supplies the
ground for the coil side of the starter relay
