A/T Shift Selector (Detention Switch)
Detention switch detects that A/T shift selector is in the P position, and then transmits the 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)
