VQ37VHR: Component Description
| Component part | Description |
|---|---|
| TCM | TCM supplies power to the starter relay and starter control relay inside IPDM E/R when the selector lever is shifted to the P or N position. |
| BCM | BCM controls the starter relay inside IPDM E/R. |
| IPDM E/R | CPU inside IPDM E/R controls the starter control relay. |
| 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. |

System Description
- When selector lever is P or N, power is supplied to starter relay and starter control relay by TCM. And BCM and IPDM E/R (CPU) detect selector lever P/N condition by the inputted signal.
- When starter operating condition is satisfied, IPDM E/R turns starter control relay ON by starter control relay control signal.
- When engine cranking condition is satisfied, BCM turns starter relay ON by starter relay control signal.
- Then battery power is supplied to starter motor ("S" terminal) through starter control relay and starter relay. And IPDM E/R (CPU) detect starter relay condition by the inputted signal.

Description
The "B" terminal is constantly supplied with battery power.
The starter motor magnetic switch is supplied with power when the ignition switch is turned to the START position while the selector lever is in the P or N position.
