Lateral Accelerometer: Service and Repair

ESP Sensor Unit

The Electronic Stabilization Program (ESP) sensor unit consists of the transverse acceleration sensor and the rotation rate sensor. They are installed in one housing under the front passenger's seat.

After replacing the ESP sensor unit, a basic setting of the transverse acceleration sensor must be performed.
