Active Engine Mount Control Unit, Component Description - GF22.10-P-2001MNB

Engine 178.9 In Model 190 

with code 466 (Active engine mount) 

Shown on model 190.377 

Location 

The active engine mounts control unit is located on the passenger side in the footwell.

Task 

The active engine mount control unit has the following tasks:

• Reading in sensors and signals 
• Evaluation of input factors 
• Actuation of assembly parts 
• Output of signals 

Reading in sensors and signals 

The input factors are read in via the following connections:

• Direct line 
• AMG CAN (CAN AMG) 

Direct line 

The active engine mount control unit reads in signals from the following assembly parts over direct lines:

• Left active engine mount pressure sensor (Y123b1)
• Right active engine mount pressure sensor (Y123/1b1)

AMG CAN 

The active engine mount control unit receives, amongst other things, the following information via AMG CAN:

• Circuit status
• Engine running status
• Active engine mount, request
• Mode, request

Evaluation of input factors 

The input factors that have been read in are evaluated by the integrated microprocessor and the relevant assembly parts are then actuated.

Actuation of assembly parts 

The active engine mount control unit actuated the following assembly parts over direct lines:

• Left active engine mount coil (Y123l1)
• Right active engine mount coil (Y123/1l1)

Output of signals 

The active engine mount control unit transmits, amongst other things, the following information via AMG CAN:

• Status of left active engine mount coil
• Status of right active engine mount coil
• Driving situation
• Recorded road surface
• Signals from left active engine mount pressure sensor
• Signals from right active engine mount pressure sensor
