Fault Code 5

Fault code 5

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

Diagnostic conditions
- Ignition on
- Terminal 58 on

Possible cause of fault
- Short circuit to voltage/ground in the supply leads between the control module and angle sensors for HBA
- Angle sensor for HBA is faulty
- The control module is faulty

NOTE:
- The 5 V supply voltage for the sensors is ensured via pin 14 on the HBA control module. A fault in this supply lead affects both angle sensors. Moisture in the angle sensors plug can lead to a fault entry.

Affected terminals
Terminals 14 and 17
