Component Description
| Component part | Description |
| 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. |
| Transmission range switch | Supplies power to the starter relay and starter control relay (inside IPDM E/R) when the selector lever is shifted into the P or N position. |
| IPDM E/R | CPU inside IPDM E/R operates the starter relay when the ignition switch is in the start position. |
| Clutch interlock switch (M/T Models) | Clutch interlock switch supplies power to the coil side of the starter when the clutch pedal is depressed to crank the engine. |
| ECM | ECM controls the starter relay inside the IPDM E/R. |

STARTING SYSTEM (WITHOUT INTELLIGENT KEY) : System Description
CVT MODELS
- When the selector lever is in the P or N position, power is supplied to starter control relay by the transmission range switch. The IPDM E/R (CPU) detects selector lever P/N condition by the inputted signal.
- When engine cranking condition is satisfied, then battery power is supplied to starter motor (“S” terminal) through starter control relay.
M/T MODELS
When the clutch pedal is depressed, battery power is supplied to starter motor (“S” terminal).
