GF42.45-P-5118RIT ESP Control Unit, Component Description

GF42.45-P-5118RIT ESP control unit, component description
- with CODE (P99) Special model "AMG Black Series"

Component Identification:

Location
The ESP, SPS [PML] and BAS control unit is located in the right rear of the engine compartment.

Task
The ESP, SPS [PML] and BAS control unit controls the following systems:
^ Adaptive Brake (ABR)
^ Speed-sensitive power steering (SPS [PML])
^ Limiter (except code (494) USA version)
^ Cruise control (CC [TPM])

The ESP, SPS [PML] and BAS control unit is the master control unit for the Electronic Stability Program (ESP) and has the following tasks:
^ Reading in of sensors, pickups and signals
^ Evaluating input factors
^ Actuation of components

Reading in of sensors, pickups and signals
The input factors are read in with the following connections:
^ Direct line
^ Engine compartment CAN (CAN C)
^ Sensor CAN (CAN H)

Direct line
The following signals are read in via a direct line:

- Circuit 30
- Circuit 31
- Brake light switch (S9/1)
- Left front rpm sensor (L6/1)
- Right front rpm sensor (L6/2)
- Left rear rpm sensor (L6/3)
- Right rear rpm sensor (L6/4)

Engine compartment CAN
The ESP, SPS [PML] and BAS control unit is a subscriber on the engine compartment CAN It communicates for instance with the following control units:

- Central gateway control unit (N93)
- ME-SFI [ME] control unit (N3/10)

Sensor CAN
The data from the following components are read in via the sensor CAN:

- Yaw rate and lateral acceleration sensor (B24/15)

Evaluation of input factors
The input factors that have been read in are evaluated by the integrated microprocessor and the affected components are then actuated.

Actuation of components
Components are actuated with the following lines:
^ Direct line
^ Engine compartment CAN

Direct line
The following components are actuated via a direct line:

- Rear SAM control unit (N10/8) (brake light actuation)
- SPS [PML] solenoid valve (Y10)
- Yaw rate and lateral acceleration sensor (power supply)

Engine compartment CAN
The ESP, SPS [PML] and BAS control unit is a subscriber on the engine compartment CAN It sends for instance signals to the following control unit:

- Instrument cluster (A1)
