CVT Shift Selector (Detention Switch)

Detention switch is integrated into CVT shift sector, and detects that selector lever is locked in the P position, then transmits ON/OFF signal to BCM and IPDM E/R.

BCM confirms the selector lever position with the following 5 signals.

• P position signal from CVT shift selector (detention switch)
• P/N position signal from transmission range switch
• 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 selector lever position with the following 3 signals.

• P position signal from CVT shift selector (detention switch)
• P/N position signal from transmission range switch
• P/N position signal from BCM (CAN)
