Control Unit For Electronic Selector Module, Task

The electronic selector lever module control unit (N15/5) receives digital and analog input signals, actuates various components or transmits information to various control units via the Controller Area Network bus Class C (engine compartment) (CAN-C). See Fig 1.

The selector lever positions and touch shifts carried out are detected in a non-contact manner by means of optoelectronic switches. A photoelectric barrier is closed or interrupted each time the position of the selector lever is changed.

Input signals:

• Transmission Mode Switch (S16/5)
• Kick-Down Switch (S16/6) (Up To 5/31/02)
• Touch Shift Module +/- (96)
• Voltage Supply (Circuit 87)

Input and output signals:

• Data Link Connector (X11/4)

Output signals:

• R/P Locking Solenoid (89)

Via CAN-C there is a connection to the:

• Instrument Cluster (A1)
• ME-SFI
• ETC Control Module (N15/3)
• ESP & BAS Control Unit (N47-5)
• EIS [EZS] Control Unit (N73)

The following information is received via CAN-C.

ESP and BAS control unit (N47):

• Wheel Speed And Right Rear Direction Of Rotation
• Wheel Speed And Left Rear Direction Of Rotation
• Set Braking Torque
• Brake Pedal Depressed

Electronic ignition switch control unit (N73):

• Circuit 50 Engine Start Switch (Circuit 50)
• Circuit 15 Voltage Supply Switched UB (Battery Voltage) (Circuit 15)
• Stop Lamp Feedback

The following information is transmitted via CAN-C:

Instrument cluster (A1):

• Selector Lever Position For Gear Display (A1p12)

Motor electronics control unit (N3/10) or CDI control unit (N3/9):

• Selector Lever Position "P/N"

ETC [EGS] Control Unit (N15/3):

• Selector Level Position
• Transmission Mode Switch (S16/5)
• Kick-Down Switch (S16/6) (Up To 5/31/02)
• Touch Shift Module +/-
• R/P-Locking Magnet (89) Energized

Electronic ignition switch control unit (N73):

• Selector Lever Position For Actuation Of Backup Lamp
