GF27.19-P-5138-02NRL Control Unit For Electronic Selector Lever Module, Task

GF27.19-P-5138-02NRL Control unit for electronic selector lever module, task
- TRANSMISSION 722.9
- with CODE (428) Steering wheel shift buttons
- up to model year 08


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, SPS [PML] and BAS 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
- 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 (S110/2) and right steering wheel gear shifter (S111/2) (vehicles up to 31.5.06 with code (428) Steering wheel shift buttons)
- Status of steering wheel gear shifter MINUS (S110/1) and steering wheel gear shifter PLUS (S111/1) (model 171.473 and vehicles as of 1.6.06 with code (428) Steering wheel shift buttons)

^ 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

^ to the ME-SFI [ME] control unit (N3/10)
- 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)
