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: Other than P and N (CVT models)
- Shifter lever: Other than neutral position (M/T models)
- Idle switch: ON (Accelerator pedal not depressed)
- Brake switch: ON (Brake pedal depressed)
ECM transmits a control signal to IPDM E/R via BCM by 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.

Precaution
Precaution for supplemental restraint system (srs) "air bag" and "seat
belt pre-tensioner"
The supplemental restraint system such as “air bag” and “seat belt pre-tensioner”,
used along
with a front seat belt, helps to reduce the risk or severity of injur ...
