Transmission Range Switch

Transmission range switch is integrated in A/T assembly, and detects the A/T 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 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)
