INPUT/OUTPUT SIGNAL CHART
*: With Intelligent Key system SYSTEM DESCRIPTION
When rapid deceleration occurs during engine runs or idle speed decreases due
to heavy load conditions,
ECM detects a decrease in idle speed and restarts the engine to secure
reliability in handleability by transmitting
a cranking request signal to IPDM E/R for activating the starter motor under the
following conditions:
• Selector lever: P or any position other than N
• Idle switch: ON (Accelerator pedal not depressed)
• Brake switch: ON (Brake pedal depressed)
Models with no Intelligent Key System transmit a control signal directly to IPDM E/R. On the other hand, models with the Intelligent Key System transmit a control signal to IPDM E/R by way of BCM via CAN communication.
IPDM E/R detects an operating state of the starter motor relay and the starter motor control relay and transmits a feed back signal to ECM via CAN Communication.
