What Does the B2109 Infiniti Code Mean?

The steering lock relay ON signal is transmitted to the Intelligent Power Distribution Module (IPDM) Engine Room (E/R) by Body Control Module (BCM) via the Controlled Area Network (CAN) communication. IPDM E/R turns the steering lock relay ON and transmits the release of the steering to BCM. The OBDII code sets when the IPDM E/R detects that the relay is stuck at OFF position for about 1 second even if the IPDM E/R receives steering lock relay ON/OFF signal from BCM.
