Description

BCM

BCM sends a starter request signal to the CPU of the IPDM E/R 
over the CAN communication lines.

IPDM E/R

CPU inside IPDM E/R operates the starter relay at the request of 
the BCM over the CAN communication lines.

Starter motor

The starter motor plunger closes and the motor is supplied with 
battery power, which in turn cranks the engine, when the “S” ter-
minal is supplied with electric power.
