LL10 Possible Conditions Not Checked

At this point the following have been verified or are true if the above steps are complete:

- Sensor strength is OK.

- Tone ring is intact with no damaged teeth and is correctly seated against the rotor hub.

- Air gap is within allowable limits and is consistent as the wheel rotates.

- Wiring between speed sensor and anti-lock brake control module is intact.

- The anti-lock brake control module has been replaced.

- The speed sensor has been replaced. The following are time consuming and should be performed only after all previous options have been exhausted.

- Verify Circuits 521 (T/O) and 522 (T/BK) are twisted throughout the wire loom. If the wires are not twisted, the anti-lock brake control module may be sensitive to any outside interference.

- Excessive axle vibration, especially over rough road can cause this issue. Verify front axle is not excessively noisy or otherwise performing abnormally.

NOTE: Blips or fallout indicate intermittent issue.

- Does signal rise consistently and evenly?

YES -- Stop. Repair is complete.

NO -- Go to LL8. LL8 Check If All Steps Have Been Completed
