Control unit for electronic selector lever module, task - GF27.19-P-5138-02NTL

The electronic selector lever module control unit (N15/5) receives analog and digital signals, it then actuates various components and sends corresponding data to various control units over the Controller Area Network bus Class C (engine compartment) (CAN-C).

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.

Internal input signals: 

• Selector lever position
• Transmission mode switch status (S16/5)
• Touch button +/-
• Voltage supply

Internal output signals: 

• R/P locking solenoid
• Circuit 58d (shift-gate illumination)

The following information is received via CAN-C: 

• sent from the instrument cluster (A1)
  • circuit 58 dimmed
• sent from the ESP control unit (N47-5)
  • Wheel speed and left rear direction of rotation
  • Wheel speed and right rear direction of rotation
  • Selected braking torque
• sent from EIS [EZS] control unit (N73)
  • Circuit 50
  • Circuit 15
  • Status of stop lamp switch (S9/1)
  • Stop lamp actuation feedback
  • Drive authorization system, stage 3 (DAS [FBS] 3) message
• sent from steering column module (N80)
  • Status of left steering wheel gear shifter (110/2) and right steering wheel gear shifter (S111/2) (up to 31.5.06)
  • Status of steering wheel gear shifter MINUS (S110/1) and steering wheel gear shifter PLUS (S111/1) (as of 1.6.06)
• sent from central gateway control unit (N93)
  • Diagnosis request

The following information is sent via CAN-C: 

• to the instrument cluster (A1)
  • Selector lever position for gear indicator (A1p12)
• to the CDI control unit (N3/9) (with diesel engine)
  • Selector lever position "P", "N"
• to the ME-SFI [ME] control unit (N3/10) (with gasoline engine)
  • Selector lever position "P", "N"
• to the EIS [EZS] control unit (N73)
  • Selector lever position for reversing lamp actuation
  • DAS [FBS] 3 messages (enable request)
• to the central gateway control unit (N93)
  • Selector lever position
  • Diagnosis request
• to the fully integrated transmission control (VGS) control unit (Y3/8n4)
  • Selector lever position
  • Status of transmission mode switch (S16/5)
