COMPONENT PARTS
Component Description
INFOID:0000000006226152
A/T Shift Selector (Detention Switch)INFOID:0000000006226153
Detention switch detects that A/T sh ift selector is in the P position, and then transmits the signal to BCM and
IPDM E/R.
BCM confirms the A/T shift selector position with the following 5 signals.
 P position signal from A/T shift selector (detention switch)
 P/N position signal from TCM
 P position signal from IPDM E/R (CAN)
 P/N position signal from IPDM E/R (CAN)
 P/N position signal from TCM (CAN)
IPDM E/R confirms the A/T shift select or position with the following 3 signals.
 P position signal from A/T shift selector (detention switch)
 P/N position signal from TCM
 P/N position signal from BCM (CAN)
BCMINFOID:0000000006226154
BCM controls INTELLIGENT KEY SYSTEM (ENGIN E START FUNCTION), INFINITI VEHICLE IMMOBI-
LIZER SYSTEM-NATS [IVIS (NATS)], and VEHICLE SECURITY SYSTEM.
BCM performs the ID verification between BCM and Intelligent Key when the Intelligent Key is carried into the
detection area of inside key antenna, and push-button ignition s witch is pressed. If the ID verification result is
OK, push-button ignition switch operation is available.
