STOP AND START SYSTEM Stop and Start Cancel Switch Circuit

DTC Code DTC Name
Stop and Start Cancel Switch Circuit

DESCRIPTION

Stop and start control can be disabled by pressing the stop and start system cancel switch (ecorun cancel switch assembly (w/o Pre-crash Safety System) or combination switch assembly (w/ Pre-crash Safety System)). The stop and start system cancel switch (ecorun cancel switch assembly (w/o Pre-crash Safety System) or combination switch assembly (w/ Pre-crash Safety System)) is a momentary-type switch that switches between on and off when the switch is pressed. While stop and start control is disabled, the stop and start cancel indicator light is illuminated to inform the driver.
