Component Identification:

Location
The Electronic Stability Program control unit is located in the left front of the engine compartment.

Task
The Electronic Stability Program control unit contains the control for the following systems:
^ Start-off assist
^ Anti lock brake system (ABS)
^ Acceleration Slip Regulation (ASR)
^ Brake Assist (BAS)
^ Electronic brake force distribution (EBV)
^ Electronic Stability Program (ESP)
^ Electronic Traction System (ETS)
^ Engine braking regulation control (MSR)
^ Limiter (not and not)
^ Speed-sensitive power steering (SPS [PML]) (with code (213) speed-sensitive power steering) Tire pressure loss warning
^ PRE-SAFE (with code (299) PRE-SAFE) Cruise control
^ Trailer stabilization (with code (550) Trailer hitch)

Discrete inputs
^ Circuit 30
^ Circuit 31
^ Stop lamp switch (S9/1)
^ Left front axle rpm sensor (L6/1)
^ Right front axle rpm sensor (L6/2)
^ Left rear axle rpm sensor (L6/3)
^ Right rear axle rpm sensor (L6/4)

Discrete outputs
^ Stop lamp actuation via rear SAM control unit with fuse and relay module (N10/2)
^ Speed-sensitive power steering solenoid valve (Y10) (with code (213) speed-sensitive power steering)
^ Power steering pump pressure regulator valve (Y10/1) (on engine 271)

Voltage supply
