Fault code 5: 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
Voltmeter display approx. 5 V
- Measure voltage between terminal 5 and terminal 1 of the sensor plug.
- Voltmeter display approx. 5 V
- In the PST2 menu item Actual values, select Sensor voltage, spring travel 1 .
- 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 or control module, replace the angle sensor for HBA, front.
If fault code 5 reappears after the plug has been removed from the angle sensor for HBA, front, there is a fault in the supply lead to the angle sensor for HBA, rear. Proceed as follows in this case:
- Pull plug off the angle sensor for HBA, rear .
- Measure voltage between terminal 5 of the sensor plug and ground.
Voltmeter display approx. 5 V
- Measure voltage between terminal 5 and terminal 1 of the sensor plug.
Voltmeter display approx. 5 V
- In the PST2 menu item Actual values, select Sensor voltage, spring travel 2 .
- 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 or control module, replace the angle sensor for HBA, rear.
