A/T Shift Selector (Detention Switch)

Detention switch detects that A/T shift 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 selector 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)
