Fault Code 0023
Fault code 0023HBA (Xenon) angle sensor, rear compression (for steel springs only)
NOTE:
- This fault can also be caused by a faulty fuse. Given this, it is advisable to check the fuse first before starting to check the wiring and components.
- This fault can also be caused by a mechanical fault, e.g. the transmission linkage or the holder for the sensor is bent or loose.
Diagnostic conditions
- Ignition and light switched on
- Internal HBA (Xenon) control module function test (once ignition and dipped beam headlight are on, a reference run is performed: headlight swivels up, down and slightly up again)
Possible causes of fault
- Signal lead to HBA angle sensor (rear compression) faulty
- Power supply to HBA angle sensor faulty
- HBA angle sensor, rear compression faulty
- Mechanical faults, linkage or holder loose
Affected pins
- Headlight mounting plate plug: pin 1
- HBA (Xenon) control module plug: pin 3
- Rear HBA angle sensor plug: pin 1, pin 2, pin 4, pin 5
