DTC DETECTION LOGIC

NOTE:

• If DTC B2618 is displayed with DTC U1000, first perform the trouble diagnosis for DTC U1000. Refer to

PCS-51, "DTC Logic"

.

• If DTC B2618 is displayed with DTC U1010, first perform the trouble diagnosis for DTC U1010. Refer to

PCS-52, "DTC Logic"

.

DTC CONFIRMATION PROCEDURE

B261A PUSH-BUTTON IGNITION SWITCH

B261A PUSH-BUTTON IGNITION SWITCH

Description

INFOID:0000000004219166

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.
