A/T Models

Power is supplied at all times:

• through 40A fusible link (letter m  , 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 (PNP) switch terminal 1 (with 4 A/T) or terminal 5 (with 5 A/T).

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

• through PNP switch terminal 2 (with 4 A/T) or terminal 1 (with 5 A/T)
• to IPDM E/R terminal 53.

Provided 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. In the event that the CAN communication line fails between the IPDM E/R and the BCM, the IPDM E/R will default to a starter relay request ON signal as long as the ignition switch remains in the START or ON position.
