Transmission Range Switch

COMPONENT PARTS

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)
