Transmission Reverse Switch

Scroll Prev Top Next More

Used to send a transmission Reverse event to the following functions:

BMW DCT gearbox control in DCT shifter emulation mode.





Used to send a REVERSE shift signal to the DCT gearbox in DCT shifter emulation mode.


Note: Even if the TCU is preventing a REVERSE engagement with it's own logic, we added extra logic into the code to prevent this signal from being transmitted to the BMW TCU.

Only sent when DCT GEAR is GEAR 1, NEUTRAL or PARK, and vehicle speed below 10km/h and the brake input is active.
