M/T Model

WARNING: This page is about a different car, the 2002 Nissan Altima. However, it is still accessible from the selected car via links, so may be relevant.

Power is supplied at all times through 40-amp 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 Intelligent Power Distribution Module (IPDM) terminal No. 11.

With the ignition switch in the "ON" or "START" position, power is supplied through 10-amp fuse [No. 12, located in the fuse block (J/B)], to IPDM terminal No. 43.

When the clutch pedal is depressed, ground is supplied to IPDM terminal No. 46 through the clutch interlock switch and body grounds El5 and E24.

Provided that the IPDM receives a starter relay "ON" signal from the BCM over the CAN lines, the IPDM is energized and power is supplied from terminal No. 4 of the clutch interlock relay, 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, the IPDM will continue to receive a starter relay "ON" signal from the BCM as long as the ignition switch remains in the "START" or "ON" positions.
