Esp Sensor Unit

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

After replacing the ESP sensor unit -G419- with the electro-mechanical parking brake control module, the ABS control module -J104- must be coded and a basic setting of the brake system (Electro-Mechanical Parking Brake) must be performed.

CAUTION:

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

Removing

-- Remove the center console. Refer to Removal and Installation

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

-- Remove the three nuts -arrows-.

-- Remove ESP sensor unit.

Installing

-- Installation is in reverse order of removal.

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

NOTE:

Do not use the nuts to forcibly position the ESP sensor unit.

-- Tighten the nuts to 9 Nm.

-- Code the ABS control module 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 (electro-mechanical parking brake).
