Electronic Selector Lever Module ESM Control Module, Task

Task 

The electronic selector lever module control module (N15/5) receives digital and analog input signals, converts these signals and controls various components or transfers information to various control modules via CAN.

In selector lever position "D" lateral touch movements in the "+" or "-" direction are detected by the electronic selector lever module control module (N15/5) via two contacts and are conveyed to the ETC control module (N15/3) via the engine compartment bus. See Fig 1 and Fig 2 .

The selector lever positions are determined by the slider position of the potentiometer and transferred to the electronic selector lever module control module 90 (N15/5).

The selection diagram symbols (shift pattern display) are illuminated by means of LEDs when low beam is switched on.

Input signals: 

• Selector Lever Position (From Potentiometer (90))
• Touch Button +/-
• Voltage Supply (Terminal 87)
• Power Supply For Reverse Lamp (Terminal 15)
• Signal For Shift Gate Illumination (Terminal 58D)
• Kickdown Switch (S16/6)
• Stop Light Switch (S9/1)

Input & Output Signals: 

• Datalink connector (X11/4)

Output Signals: 

• R/P locking solenoid (89)
• Power supply and ground for potentiometer
• Reverse lamp (via the light module (N7-1)).

Via The Engine Compartment Bus, There Are Connections To The: 

1. ETC (EGS) Control Module (N15/3)
2. Traction System Control Module (N47)

The Following Information Is Received: 

Traction system control module (N47)

• Rear Right Wheel Speed
• Rear Left Wheel Speed

The following information is sent: 

ETC (EGS) control module (N15/3)

• Selector lever position
• Kickdown switch (S16/6)
• Touch button +/-
