Component Description
| Component part | Description |
|---|---|
| TCM | TCM supplies power to the starter relay inside the IPDM E/R when the selector lever is shifted to the P or N position. |
| 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" terminal is supplied with electric power. |
