Transmission Range Switch

Transmission range switch is integrated in CVT assembly, and detects the CVT shift selector position.

TCM receives the transmission range switch signal and then transmits the P/N position signal to BCM and IPDM E/R.

BCM confirms the CVT shift selector position with the following 5 signals:

• P (Park) position signal from CVT shift selector (park position switch)
• P/N position signal from TCM
• P (Park) 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 CVT shift selector position with the following 3 signals:

• P (Park) position signal from CVT shift selector (park position switch)
• P/N position signal from TCM
• P/N position signal from BCM (CAN)
