Manual +/– Steptronic Switch The manual +/– switch is located on the left hand side of the selector lever assembly. The switch comprises a housing which provides the location fora sliding contact. When the selector lever is moved to the manual/sport position, a dog on the lever engages with a slotted abutment on the switch sliding contact. When the lever is moved to the + or – position the dog moves the switch completing a momentary earth circuit with one of two microswitches at each end of the switch which correspond to the + or – positions. This momentary signal is received by the EAT ECU which, on first operation of the switch, initiates manual mode and operates the transmission in the selected gear. In this position, a spring will move the selector lever to the centre position when released.
