Fault-Tracing Information

Fault-tracing

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 wiring and connectors

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

Checking the wiring and connectors
Check the connectors on the brake control module (BCM) and the wheel sensor in question sensor for contact resistance and oxidation.
Check the connectors and wiring insulation for damage.
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

Fault-tracing information
The fault should have been detected and remedied. As this is not the case fault-tracing has failed.
Exit fault-tracing for this diagnostic trouble code (DTC) or make another attempt.

Do you want to exit fault-tracing?

Yes - Exit fault-tracing

No - Attempt New Test
