Fault code

5 V supply for axle position sensors (angle sensors for HBA)

This fault is stored in the following cases:

1. Short circuit to voltage/ground in the supply leads between the control module and angle sensors for HBA

2. Angle sensor for HBA is faulty

3. The control module is faulty Note:

The 5V supply voltage for the sensors is ensured via terminal 14 on the HBA control module. A fault in this supply lead affects both angle

Elimination:

- Switch off ignition

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

Read the fault memory and observe whether fault code 5 reappears.

If fault code 5 does not reappear, the supply lead to the angle sensor for HBA, front, is faulty. Proceed as follows in this case:

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
