Component Parts: TCM

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