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:
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.

On board diagnostic (OBD) system
Diagnosis Description
This system is an on board diagnostic system that records exhaust
emission-related diagnostic information
and detects a sensors/actuator-related malfunction. A malfunction is indicated
by the malfunction indicator
lamp (MIL) and stored in ECU memory as a DTC. The diagnos ...
