Parking Brake Control Module: Service and Repair

Electromechanical Parking Brake Control Module

The electro-mechanical 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, 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.

- Remove the three nuts - arrows -.





- Disconnect the connector - 1 - from electro-mechanical parking brake control module.

- Remove electro-mechanical parking brake control module.

Installing

- Installation is in reverse order of removal.

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

• Do not use the securing nuts to forcibly position the electro-mechanical parking brake control module.

- Tighten the nuts to 9 Nm.

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