Push-Button Ignition Switch

PUSH-BUTTON IGNITION SWITCH

Description

BCM transmits the change in the power supply position with the push-button ignition switch to IPDM E/R via the CAN communication line. IPDM E/R transmits the power supply position status via CAN communication line to BCM.


Component Function Check


1. CHECK FUNCTION

1.Select "PUSH SW" in "Data Monitor" mode with CONSULT.
2.Check the push-button ignition switch signal under the following condition.
