M9 Check If All Steps Have Been Completed

- This step requires that a valid diagnostic trouble code has been obtained, all prior diagnostic steps have been completed, and the affected wiring integrity has been verified.

CAUTION: If the above is not complete, chances are that replacement of this or any other system component without specific direction will not, in most circumstances, resolve the concern and will consequently result in customer dissatisfaction.

- Have all prior diagnostic steps been completed as described above?

YES -- Replace speed sensor. Go to M10 for system verification. M10 Check For DTC Repeatability

YES -- If no resolution, replace anti-lock brake control module. Go to M10 for system verification. M10 Check For DTC Repeatability

NO -- GO to last diagnostic step completed and continue.
