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).
