ESP Sensor Unit -G419-

The transverse acceleration sensor -G200-, rotation rate sensor -G202- and the longitudinal acceleration sensor -G251- are installed in one housing, together with the electromechanical parking brake control module -J540- under the center console.

After replacing the ESP sensor unit with the electromechanical parking brake control module, the ABS control module -J104- must be coded and a basic setting of the "Brake system" (Electromechanical Parking Brake) must be performed.

WARNING:

Excessive shaking (for example, dropping, impact) may damage the ESP sensor unit. The ESP sensor unit must then no longer be used.

Removing

-- Remove the center console. Refer to "Storage Compartments, Covers and Trim" in Removal and Installation .

-- Disconnect connector -1- from the ESP sensor unit.

When installing ESP sensor unit, be sure it is properly seated on the bracket and is free of tension.

NOTE:

Never force ESP sensor unit into position using nuts.

-- Tighten the nuts to 9 Nm.

-- Code the ABS control module with the vehicle diagnostic tester in "Guided Fault Finding".

A steering angle sensor -G85-, transverse acceleration sensor, brake pressure sensor 1 -G201- and longitudinal acceleration sensor basic setting must be done.

-- Perform basic setting for "Brake system" (Electromechanical Parking Brake).
