Checking the wheel sensor and pulse wheel




- Ignition off.
- Remove the wheel for better access.
Check that wheel sensor in question is tight against spindle or hub. Check that there is no dirt between the sensor and mating surface.
Check that the magnetic pulse wheel is correctly secured and free of damage, scratches (for example scratches, deformation).

Were any defects found?

Yes - Verification

No - Checking the brakes and wheel bearings

-------------------------------------------------

Checking the brakes and wheel bearings

Hint: A binding brake may block some or both wheels when driving. This will mean that the wheel sensor signal is not transmitted.

Check that the brake calipers are not sticking and locking the wheels.
Check the wheel bearing on the relevant wheel for play. Check that the wheel rotates freely and is not sticking.
Check that the wheel sensor cables are not too close to sources of interference.
Remedy as necessary.

Verification

Hint: After carrying out the repair, check that the fault has been remedied.








- Ignition off.
- Restore components and connectors.
- Ignition on.
- Test drive the vehicle following:
Check the ABS warning lamp during the test drive. If the fault has been remedied the lamp will go out when the speed exceeds 20 km/h. If the warning lamp does not go out, return to the workshop and read off the diagnostic trouble codes (DTCs).

Does the ABS warning lamp go out and remain unlit?

Yes - FAULT FOUND

No - Fault-tracing information
