Control Module

The electromechanical parking brake control module -J540- and the ESP sensor unit -G419- are installed in one housing under the center console.

After replacing the electromechanical parking brake control module with the ESP sensor unit -G419-, 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. 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 .

-- Remove the three nuts -arrows-.

-- Disconnect the connector -1- from the electromechanical parking brake control module.

-- Remove electromechanical parking brake control module.

Installing

-- Install in reverse order of removal.

When installing electromechanical parking brake control module make sure it is correctly seated in its mounting and is free of stress.

NOTE:

Do not use the securing nuts to forcibly position the electromechanical parking brake control module.

-- 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 -G200-, brake pressure sensor 1 -G201- and longitudinal acceleration sensor -G251- basic setting must be done.

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