B2619 BCM

Description

INFOID:0000000004216056

BCM requests IPDM E/R to supply power to steering lock unit. After receiving the power, the steering lock unit

transmits an ON signal to BCM.

B261A PUSH-BUTTON IGNITION SWITCH

Description

INFOID:0000000004216059

IPDM E/R transmits the push-button ignition switch status via CAN communication to BCM. BCM receives

push-button status by hardwire input. BCM compares the 2 signals for mismatch.

DTC DETECTION LOGIC

NOTE:

• If DTC B261A is displayed with DTC U1000, first perform the trouble diagnosis for DTC U1000. Refer to

SEC-28, "DTC Logic"

.

• If DTC B261A is displayed with DTC U1010, first perform the trouble diagnosis for DTC U1010. Refer to

SEC-29, "DTC Logic"

.
