This fault is stored in the following cases:

1. Short circuit to ground or open circuit in the circuit between control module and servomotor for HBA, right,

2. Servomotor for HBA, right, is faulty

3. The control module is faulty

Elimination:

- Switch off ignition

Pull plug off the control module Pull plug off the servomotor for HBA

Check for open circuit in the supply leads to the servomotor for

Ohmmeter display < 5 Ohm

Check for short to B+ in the supply leads to the servomotor for HBA Ohmmeter connected to terminals 5, 6, 7, and 8; measure resistance

Ohmmeter display

Check for short circuits between the leads.

If no fault is detected in the wires, replace the servomotor for HBA.

Fault code 3

Axle position sensor, front (angle sensor for HBA)

1. Short circuit to voltage/ground or open circuit in the supply leads between the control module and angle sensor for HBA, front

2. The sensor linkage is disengaged or faulty

3. Angle sensor for HBA, front, is faulty

4. The control module is faulty Elimination:

Visually inspect the sensor linkage and check the plastic holder of Switch off ignition

Pull plug off the angle sensor for HBA, front Switch ignition on

Measure voltage between terminal 5 of the sensor plug and ground

Measure voltage between terminal 5 and terminal 1 of the sensor

Voltmeter display approx. 5 V

In the PST2 menu item Actual values, select Sensor voltage, spring

Connect a jumper to terminals 4 and 5 of the sensor plug PST2 display approx. 5 V

If no fault is detected in the wires, replace the angle sensor for HBA.
