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.
How to set srt code
Description
OUTLINE
In order to set all SRTs, the self-diagnoses as in the “SRT ITEM” table must
have been performed at least
once. Each diagnosis may require actual driving for a long period of time under
various conditions.
