Transmission Range Switch

COMPONENT PARTS

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)
