Component Parts: TCM

TCM transmits the shift position signal (P/N position) to BCM and IPDM E/R via CAN communication.

BCM confirms the CVT shift selector 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 CVT shift selector 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)
