System Description

Power is supplied at all times:

• to starter motor terminal B, and
• through 40A fusible link (letter k  , located in the fuse and fusible link box)
• to ignition switch terminal B.

  With the ignition switch in the START position, power is supplied:

• from ignition switch terminal ST
• to IPDM E/R terminal 4.

  With the ignition switch in the ON or START position, power is supplied:

• through 10A fuse [No. 12, located in the fuse block (J/B)]
• to park/neutral position (PNP) switch terminal 1.

  With the selector lever in the P or N position, power is supplied:

• through PNP switch terminal 5
• to IPDM E/R terminal 53.

  Ground is supplied at all times:

• to IPDM E/R terminals 38, 50 and 60
• through body grounds E9, E15 and E24.

  Provided that the IPDM E/R receives a starter relay request ON signal from the BCM over the CAN lines, the IPDM E/R grounds the starter relay and power is supplied:

• from terminal 3 of the IPDM E/R
• to terminal S of the starter motor windings.

  The starter motor plunger closes and provides a closed circuit between the battery and the starter motor. The starter motor is grounded to the cylinder block. With power and ground supplied, the starter motor operates.
